Color of Flash-light

As now, photography is open to anybody and bast majority of the camera user has no

interest to the technical aspects surrounding the photography, while expecting the

manufacturer provide everything what they needs perfect.  

Hence, they don’t even care whether it is DSLR or Phone-camera.  

[]

So, everybody believing flash-light is the flash-light and all same.   Though, it is not true

—– some are more blue.  Even a professional studio photographer may not noticed but

just believing “As long as they buy reputed studio flash, it is the industrial standard”.  

In certain extent, it is true.   The quality of the flash has been really improved. (and

became very cheap.)  😉

[]

The photo above, they are the flash-tube, most left came from Bowens. (are they still exists ?) 

Second is Balcar’s  —– (mind you this tube alone costed £200 !)   Third is for ring flash-light.

(This is the Ring-flash I made for the photos which was published in the Zoom Magazine.

= Ring Flash for Fish-eye Lens. —– Since, the subject was over-shadowed by the camera itself,

it was necessary to illuminate !    Still, the lens has 180 degree of view, flash has to be exactly

in the same plain of the lens-front. = If the flash was before the lens, it will be in the picture.  

If it was behind the lens, the shadow of the lens will appear in the picture.  😀 )

[]

Though, this flash-tube was very blue (about 6500 K) I needed to use a Kodak Color

Compensation Filter inside of flash. — Most of the flash produces  6000 K Color-temperature.

Though, the standard of the Printing Industry is 5500 K,  so that photo above, Bowens tube was

gold color tinted to warm-up the color a bit.  This slight difference makes the skin-tone better.

= So, you may try to tinker the flash-light, such as stick a cello-tape on the flash face and put a

red line of maker-ink (never draw an ink direct) —– it would make

the faces in a party looks more drunk.  😀

 

Gauzed Image or in a Reflection — My Answer to Elena’s Paintings

When I saw the paintings in a fantastically talented artist Elena Caravera’s blog, of which

a girl’s portrait was overlaid by gauze like white, I found there is somewhat similar psyche

exists in the mind of the painter  = in order to give a psychological depth, intentionally cover

the painting and make the image fuzzier.

[] 

Strangely you may think, I’ve been creating “Not sharp” photos intentionally over 40 years.  

Since I started my photography taking the photos of Nature, and the close-up photography had

become my part-time job when I was in my Uni’,  to make clear sharp image became a norm

and a routine, then I started to go further departing from cosy home of normal photography.    

In our generation, some photographers gone to the rough-grain image such as Moriyama

or the subject the society despised such as Araki, etc.  but I was rather enchanted by the

ghost of the image, which we can’t see, or hidden behind of fuzzy or double images. 

Since then, I tried Soft-focus lens, Improvised, modified lens, Lens from an old folding camera on

a handmade camera etc. to see fuzzy image or the image on a reflective surface —– see through

a distorted glass material etc. —– I got thousand of this kind of photos.

[]

Photography is a COPY of the subject.  = The more realistic and the closer to the reality of the

subject, it become mere substitute of the real thing.  It’s better to see the real thing if possible.  

But when its reality was lost, its image started to have its own mind.  Whether it is in fact my

own mind or the curse to the image, it start to assert its own voice = the photo became

independent of the subject.  —– or, that’s what I’m thinking.  😉  

Though, I don’t know, what Elena is thinking.  😀

Slide Dupe by D810 HDR

Since many of my old films came out of boxes, I tried to make some digital dupe of them.

The main reason why I bought canon 5D Mk-III was that it has HDR (High Dynamic Range) built-in. —– (Though, it turned out to be unusable unless it was processed in PC with their DPP program. ( PS : It was the result of first test, hence I’ve given-up to use though, I tested again further and I found that it works in the most of the subjects = so, fair to say it was NOT unusable = some of the lighting condition and a combination of the lens may show unsatisfactory result. )   In contrast, Nikon D810 seems to be a bit subtle but it is quite useful as the camera alone gives processed image on the spot.  (Even hand-held shot, if the exposure difference was within 3 stops, it works reasonably — not perfect though, don’t ask too much = effect is somewhat similar to put a big reflector to brighten-up the shadow.)

———- (Photo Left :  Straight Copy.      Photo Centre :  with HDR.      Photo Right :  HDR and + 1/3

———- Which one to choose would be depending on one’s tastes ? )    ( St. German-de-Pre, in Paris)

So, the sample photos here are the Digital Copy of the Film slide.  The Originals were the Kodachrome ISO 25 film.  (Almost  40 years old.)

Copy Camera was Nikon D810 with Micro Nikkor 50 mm, and using their HDR setting.

What ever a way when Copy was made,  whether by film or Digital means,  the range of the tones would be lost and became higher contrast. 

Photo Left : This was a straight Copy and the Right : was with HDR.

(Original Dynamic Range of the Kodachrome was squeezed into narrower range, hence lost its original sparkle = photo looks dull now) —– Mind you, the  original Kodachrome 25 has the detailed tone in its highlight and in the shadow as well. = Otherwise, where the details on Music Score came from. —– (Camera couldn’t create, if no image was there.)  😀

—– In this extent, the resolution of Digital Camera may surpassed the resolution of such as  Ektachrome film though, the Dynamic Range of the Kodachrome yet. 

= With the use of HDR, they may just come closer to emulate the film.

 []

(This Dupe was made using Flash-light and Canon 5D Mk-III without HDR, and the photo was brighten-up a bit on after tinkering process.  —– not much difference to above HDR photo.)

[]  There is a funny misunderstanding among the people  —– People has been fooled by a word / technical term such as “Number of BIT” = To express color depth by 8 bit or 12 bit etc. those number is an indicator of “How finely divided” (Say, 2 bit mean Black or White.  8 bit mean, the staircase of darkest Black to brightest White was divided into 256 steps, that all).  

From darkest to the brightest, how many times (in exponential scale) brighter is the Dynamic Range or in old term, Latitude. 

The B/W film was known to have a Latitude of 7 stops  ( = in metaphor, a grey become Black on F 22 but if the aperture was open 7 stops to F 2 the same grey will be captured as white.)  And the Color films and TV Cameras got only 5 stops of Latitude. (That’s why TV needs many lights.)

Even after the digital revolution, the situation hasn’t been changed much, since there is NO such things like a digital sensor = the sensors and the display units are all in analogue. !   All due to the limitation of those electronic components.  

(You know, the darkest black you can see on the screen is the darkness when you switch off your device. —– Is it dark ?  😀 )

(Usable linear part of their character is limited by such as quantum mechanics. ) 

[]The most of ignorant photographer who “worship” Raw File is believing it has more though, it is like a 1′ scale and a 30 cm scale.  Metric scale looks divided finer than inch scale, Raw is a bit finer that’s all.  Lossless JPEG compression wouldn’t make so much difference to Raw.

Raw doesn’t have extended Black outside of  30 cm or White on top.  

The total length is still the same.

[]The wide coverage of  the ISO setting in a DSLR was achieved by the higher amplification of the output from the censor = if the sensor was designed for low-light,  the highest output under bright light was also lower.  = Because, the sensor has almost the same latitude or dynamic range.  I wonder, if any DSLR which has 2 stops more Dynamic Range come to the market ?  

(Of cause with one exposure.   I don’t mind if it got digital signal process built-in for this purpose.  —– Or are they expecting the people resort with after process ? —– ( PS : Some information educated me.  Now such as Panasonic’s Lumix camera and their image processing program is even correcting the aberration of the lens = It is really the electronic company’s answer to the optical problem = not by the optical design but by their own trick = electronics !  )

Google Search

It seems that from the eyes of Google, I may fallen into a category of the least useful

data in their business.    Despite the fact that the owner of WordPress (is Google)

putting quite big companies AD into my blog and making money, still my own  “Profile”

and ID are useless such as my Mail address, user name on Youtube, not mention this

very Yoshizen couldn’t be congregated to one ID.

To define the ID can make the Person (with all the associated Information, even oversaw

history of search record, the contents of Email) as a clear target of AD = convincing

profile to target an particular AD to a potential buyer of their product.

Not only my ID but also the theme or contents of this blog is too wide-spread = hard to

define the main subject, not just peaceful Buddhism, not necessary the Art, or simply a

Photography —– and why the strange Cooking here ? ? ?

[]

Until a year ago, to find my post by Google Search was very easy, just type search-term

such as  [Tree of the Life],  [Bodhi-tree] etc. would lead to my post on the first page of

Google list, if not on the top, reflecting the number of hits of which people has made.

(It was automatically done by their Search-engine algorithm.)

Then Google has changed it, and [Tree of the Life] [Bodhi-tree] were disappeared and more 

commercial items such as selling books or an AD of a Tour visiting India got the priority.

It seems, [Cooking Daikon Zen] is still coming up on top of Google-search though,

the other one such as  [Cooking aduki-bean Oshiruko]  which used to came on top too

had almost completely disappeared while showing thousands of other items which got

just a single word [aduki] or [oshiruko] even contain just [Cooking].   Otherwise, only

searching by  [Cooking aduki-bean Oshiruko Yoshizen blog]  will show my post.

Read a screen shot above “ No results found for Cooking Oshiruko Yoshizen Blog”  looks

very funny isn’t it = their automatic search algorithm couldn’t see the title of my post.

— Really ?   (What sort of manipulation behind here ?)  😀

—– Is this because of they thought I’m not a profitable customer (who isn’t very cooperative

for their business term.) ?    Regardless, a quality of the information of which my post got.

(Please read it = How do you think — and try to test the  Google-search  by yourself =

you may see,  next target could be you.)

[]

Funny fact was, when I found that the Google Image was showing the miner picture of

[St.Lucia] laying on the sand (?) instead of the main figure which was receiving lightning,

I mocked them “Haven’t they got the eyes to see the Art ?” and posted the photo on Google+

(as I suspected that the people who didn’t join G+ may be getting a raw-deal )

—– then the post [St.Lucia] started to came-up on the top page of 13,700,000 items on their list.

—– Why funny wire figure came above much more important picture of the religious paintings

of the old masters’ in the museum.

This signified the fact that the Google listing was not operating neutrally by the

automatic algorithm like what they says, but by the people who got a certain intention.

Google might be aiming to become the force in the “Big brother’s System” = The Ruler

though, it is a direct confrontation with the Dharma / Law of the Universe or just

obvious common sense.  

Who do they think they are ?    Are they thinking, they are the auditor of the world ?

[]

PS :  Yet more funny story was, after I’ve put this post, my friend who tested this, found

that my post  [ Cooking Oshiruko]  came back to the top page again.  😀 —- Who is watching ?

[]

The company who cross the line to become too greedy seemed to get a punishment of the

Dharma.   Such as a company even I, a small man on the street disliked because of their

over-stepping business practice,  get their own cause boomerang-back.

10 years ago I really hated Microsoft. —– Then, they tumbled down, being accused of their

monopolizing business practice.   And the Apple who I really hated, saw the same fate.

( remember what happened to Steve Jobs.)   It seems this is the turn of the Google —–

I’m very very interested in to see what would happen to them.   😉

(It may not necessary come from the front door straight to their business tactics such as

from the rival businesses, but it could come even from the back.)

(PS:  Funny coincidence —– I just found this article in the Wall Street Journal =

Yahoo tops the net traffic over Google) = When I think, everybody think the same too !

[]

In principle, the Dharma should be the all the existences which is in the invisible “Void”

without having Self or its own mind.

It is like a huge machine operating in rational interaction, —– though, in its invisible

unknowable part of the Dharma still seems to have a will to determine our fate.

Though, this “Will” kind is not whimsical or impartial, but simply tells wrong is wrong,

right is right —– to the larger and longer term extent and to the balance of whole Universe.

Because we human-being is too small to know whole extent of the mechanism of the

Universe, we have to leave it as unknowable still, simply it is “Yet we know the whole”.

We are discovering more and more, still we never found anything irrational =

everything down to the sub-atomic particles to our mind mechanism still keeping its

rational cause and the effect linkage. = nothing bore-out from nothing miraculously.  

So, simply, when we (even a company) did something wrong, it creates a distortion in

a balance of the Dharma ===> causing repercussion which we called Punishment.

This mechanism is the System Principal of the Cause and the Effect,

the Linkage mechanism which was called Karma and they are the very Teaching of  

Lord Buddha.

Grown-up with Pain

It seems the Politicians are arguing about yet another law to deal with “Dangerous Dog”

after many cases of the children (even Policemen) were attacked, even by their family dog.

[]

To my eyes, there lies a fundamental problem of our society’s attitude toward the animals

and the nature in general.

I’ve seen a very small child run to cuddle even a big dog which is somebody else’s dog.

May be as a civilized people, we should be friendly with animal etc. though, animal is

the animal for ever.  May be thousands of hart-warming story of the friendship between

human and animals, though, we shouldn’t forget that we are only a part of the Fauna,

and other part of the member never belong to us, let alone dictated by us.

Our apparent dominance is just a superficial pictures.

[]

Be friendly but cuddling them like a Soft Toy is totally different matter. —– have you

ever seen the dogs hugging each other ?   Or does cats do it ?   Only Primates hug !

Even if it is familiar picture to a dog, suddenly a small child who’s smell is totally

unknown, come close and start hugging, the dog react their own way —– could

bite-back, scream and the smell of blood only excite them.

We shouldn’t mistake, “Be friendly” doesn’t mean “THEY also act like Soft toy made

by human” — we need to distinguish and treat them as another member of the Fauna

who could still be dangerous.

[]

Same misconception is in the education, publication etc. = with a sort of

“Humanitarian Ideas” = treat others as equal, not to be violent, etc. or talking about

not giving “Psychological Trauma” etc. (even seek a damage compensation against it).

(Worst is in Japan, in the children’s book all the fearful image of such as Wolf or any

Dangerous animal has been disfigured into cuddly cute “Figure” and even the

carnivorous Ogres became just another member of a democratic society!

(Ogre is the symbol who AGAINST the society = counter reference = they got to be bad !)

In the other hand, a Manga or Game Hero uses all sorts of lethal weapons to kill

enemies in the most violent way, was not checked.

So, a kids grown up without learning a pain (to the self = to the others) does the most

horrifying killing when he or she (these days, women has been committing really

dreadful killing = it seems they really found the equality) commits a murder.)

[]

NO! Grown up is a process to learn with Pain.  Its trauma is the basis of the imperative

memory “What we have to pay attention” and the teachings of DO and NOT DO.

—– We intelligent civilized people “can” understand what was told or written, is false.

The notice or warning was for the excuse of the liability of the Authority. = I told you.

(Please note, I’m not advocating a teacher, instructor sort, resorting with a physical

violence or harassment in order them to enforce their “idea” to the students.)

[]

Respect the Nature is to accept that they got their own Karma hence rightfully exists in

this Planet = Respect WHAT THEY ARE, not impose our idea such as faithful cuddly dog

or beautiful song bird etc.   To lean this without pain, it wouldn’t be sublimated to the

bottom of our subconscious, and reflect it to our behaviour or perception.

—– In most of the situation, our behaviour, perception were not controlled by our

civilized conscious thinking but invisible subconscious.  We only think after.

( —– by the way, I don’t intend to offend the unfortunate victim mowed by the dog.  

I really feel sorry for them. —– especially, me too, can’t get on well with the dog

= as, I’m a cats person. 🙂 )

Mind in the Syber Space (and Under the Hormone)

There was a rather sad news on the radio that a girl committed a suicide after bullied on SNS.

In reality, it was only a line of letters on a screen, still we take it as a message from somebody

and interpret it in a certain context —– some time too seriously.

(And in this case it even caused a girl to hang herself.) 

[]

With Twitter accounts in my name  (though, whether they are “mine” or not is arguable since

they are created by somebody else. :-))  I used to receive a lots of direct massages to my Email,

of which most of them were saying  “Somebody spreading dreadful rumour about you ~> See

this”  or  “lol, I laughed so much of this picture of you ~> See this”   and lure to get virus or 

see AD —– (Though, I only guess, since I never ever clicked and open. I don’t know what’s there.

Then I set a filter “Twitter, Direct massage” automatically go to the bin.)

= The reason is that there is absolutely no possibility, somebody I don’t know can make any

serious rumour about me, or post a photo with my name on it (since, all of my ID is fake.)

Other reason is, if it was true, it must be a fun to other people = enjoy it yourself.

Make the world smiley place is a good things, why not ?

If anybody doing it on behalf of me, I’m very much thankful. 😀  

[]

To deal with Syber Space, I prepared to the worst scenario, hence I don’t give real ID as

much as I can.   As I got friends who are (were?) Anarchist, Hacker, (ex?) Terrorist, etc etc. and

know a bit of computer, I’ve seen a program which can generate all the combination of possible

Password and hack-in etc etc. = I don’t trust so-called Security at all.

So, if I got to do Net-shopping I use a bank account which got only just-enough balance left.

False ID to each registration prevents two information joint together.

(You know, First name + Post code can find “Who you are and the full address”. To add DOB can

access NHS data. From here, to hack-in to Banking data is just a matter of keyboard. etc etc.

—– And on top of those, such as Google is keeping all of our Net history in their side.

A hidden file of Picasa is keeping extract sample photos of naughty site you’ve visited.(not me) 🙂

—– search your HDD, [Photograph, Picasa, Information] or check ALL the files in your Picasa!

—- and those information has been given to the National Security.  You remember?  ! ! !)

We are completely naked in the Net.  = So, remember to use snail-mail if you are dealing with

something dubious.   Utilize a convenience of Internet, free of cost, having certain trade-off.

 

We human being is a social animal, and rather vulnerable existence, hence very susceptible to

the environment and the social-environmental condition.   Therefore, we were genetically

programmed to pay attention to others, though, to take other’s words too serious is a trouble of

the person who read it. = It is a juggling work.   To listen what other’s say might be important, but

in the same time, to detached from it, is also important.  Other’s words could be crucial though,

just put a distance and think “Who the person bother to send such a message is ? And what’s the

intention ? Hasn’t this person got anything else to do ?” = such observation will shed a light to

the situation. —– And much more importantly this detached mind-set prevent us

to be deflected by the emotion.

[]

Still, to take an other’s message in certain context is depend on the mind of who read it.

In a philosophical view, the things in the world is not really existing but only in the mind,

let alone such as a message in the Net. = It is an indirect-indirect flimsy existence.

And physically they have no danger. Just delete it.

And the Buddhists may not believe the Self is even a real existence = if the Self is not there,

why afraid to be harmed or lost in a Syber bulling.

[]

 Yet still, if you take matter in a mind too seriously, this article may show you the reality,

Mind is not a kind of Holy existence in a mysterious sanctuary.    There may not even be a

so-called spirituality.    They might be all in a delusion.

The two faces of the “love hormone”

By Brian Dodson

August 6, 2013

Often called the love hormone, oxytocin has shown the ability to enhance social bonding,

decrease anxiety and encourage an overall feeling of satisfaction with life. A new study out of

Northwestern University, however, finds that this ancient hormone has a dark side, and is capable

ofstrengthening unpleasant memories, fear, and anxiety. This Jeckyll and Hyde behavior results

from the fact that oxytocin has a general strengthening effect on social memories, without regard

to their polarity.

Although discovered in 1906, study of the emotion-altering effects of oxytocin are still in their infancy.

Experiments on humans as well as animal models strongly suggest that oxytocin is associated with

pair bonding, social recognition, ethnocentricity (the “in group” effect), increasing trust, decreasing fear,

and even improved wound healing. An interesting example of this class of effects can be found in a

2012 study which showed that oxytocin caused men in a monogamous relationship to maintain

four to six inches more space between themselves and an attractive woman in a crowd, while

having no effect on single men.

Other, less positive properties of oxytocin dosage have also begun to be reported.

For example, a study from the University of Haifa found that the emotions of envy and

Schadenfreude (pleasure in another’s misfortune) were increased by internasal administration of

oxytocin. Further research suggests people with borderline personality disorder, whose major

symptom is a tendency to withdraw from social interactions, exhibit less trust when treated with

oxytocin. This was particularly true in those who were sensitive to rejection. Clearly, oxytocin’s

effects on people’s emotions are not as simple as originally suggested.

This new study from Northwestern University demonstrates that oxytocin is associated with

emotional pain. In increasing the strength of social memories, it may be the reason that stressful

social situations (bullying, abuse, ridicule, rejection) can easily be brought to mind long after the event.

The intensity of such memories can be such that the memory feels almost like living through the

original event every time you think of it.

The Northwestern study, carried out by Dunbar Professor Jelena Radulovic’s group, found that

during a stressful social experience, oxytocin is released and activates a part of the brain that

intensifies the memory. Oxytocin also increases the susceptibility to feeling fearful and anxious during

stressful events going forward. It seems likely that oxytocin also intensifies positive social memories,

but this has not explicitly been examined as yet.

Professor Radulovic’s study is the first to link oxytocin to social stress and its ability to increase

anxiety and fear in response to future stress. The researchers also discovered the brain region

responsible for these effects – the lateral septum – and the pathway or route oxytocin uses in this

area to amplify fear and anxiety.

The findings surprised the researchers, who were expecting oxytocin to intensify positive emotions

in memory, based on its long association with love and social bonding.

“Oxytocin is usually considered a stress-reducing agent based on decades of research,” said

Yomayra Guzman, a doctoral student in Radulovic’s lab. “With this novel animal model, we showed

how it enhances fear rather than reducing it and where the molecular changes are occurring in our

central nervous system.”

Far from a simple “cuddle hormone,” oxytocin appears to have the same complex interaction with

human health and behavior as most other hormones. While a good deal of progress has been made,

there is still work to do when it comes to to unknotting the tangled ball of yarn that is oxytocin’s effects.

PS:  If you are a hard-core Spiritualist, you may not happy with this kind of materialistic

view though, this view doesn’t conflict with Lord Buddha’s teachings at all. Far from it, 

Lord Buddha’s fundamental teaching of the Karma = Cause and Result is nothing but a

Scientific Rationalism.   Hence, when one dies, its mind, spirit goes with.  No Atman exists.

Nutrition of the soil and the water with plenty sun, the plants grows.

This is nothing but the science.  Hence, the Testosterone in a body drive a man to do the sex.  

So, here the Physiologists talked about how Oxitocin causes in our body and gives the effects

to the mind. ——  This is the Very mechanism of the Karma.

Zen in Action (3) — Latent Thinking

At moment, I’m in chaos of shifting the mountain of boxes again. Some of the regular readers

may remember, I said the same before, though it was for fitting new window but this time it

is for electric re-wiring. It’s mean, I have to shift those to the window-side to vacate the

wall-side for the electrician to access all the power-points, switches etc. (I’m not happy at all.

= so-called Electric safety standard has been changed and they say all the system has to be

kept-up, blah blah = keep industry busy to make money, but I’m dubious about

why the contract has gone to this company.)

So that, fortunately or unfortunately, I had to dig-up the boxes berried to the bottom which

I haven’t seen since when I moved to here.

[]

In common-sense, people only has what is essential to the own immediate life, the essential

for the daily life. —– ideally a Buddhist remained in their bare minimum though it’s the matter

of how the person define who he is = a Buddhist bikku (literally a beggar who forsaken all his

possession for a sake of seeking the truth) may needed to have one cloth to cover his body and

one bowl to receive food (then to drink, and take a water to wash himself etc.)

—– in this context when I found that the followers of

Lord Buddha had umbrella, I was very surprised (let alone the umbrella had been already

invented then ! —– this sort of analysis would lead to see the timing when Agama Sutras was

written, or its authenticity.)

[]

In fine day, still carry an umbrella for if it starts a rain, or carry a bowl in case if anybody

offer a food are all in the speculation (may happen but not on that moment) = in other words,

it’s only in the mind.     I wonder what Lord Buddha instructed to this matter to his followers ?

So, the teaching of “Live in the Moment” include the situation “Could happen next moment” too.

So, I carry a mountain of material to make something which could happen in any moment. 😀

[]

Don’t cling to your thought but leave the matter to the Dharma (occurrence of the Karma).

This “thought” meant be a kind of thinking we are doing in lingual form. —– as a matter of fact,

as Neuroscientists found that 90% of our thinking has been done subconsciously without convert

it to the lingual form. Even when we are in Mushin and totally occupied by one action, our Brain

is still in full working state unless we choose to have meditative state.

This “subconscious thinking” is no other than what we call [intuition], [hunch], and often giving

an [insight], or [inspiration] and those are the very “Latent Thinkings”.

[]

In comparison, what we learned in lingual form such as somebody’s words or what we learned

from the books will stay as the lingual memories.

We can say “I understood” is in fact, lexical understanding of an abstract notion of the word and

its meanings but not what it is in practice.

But what we experienced and learned in real life always carries the tag of emotion yet this

emotion is very difficult to convert and express in the words, because the tag in the emotion is

a part of the said “Latent Thinkings”.     In most of the case, lingual memory stay like a distant

objects and not necessary relate to the emotion hence, it is not necessary takes a part

in the “Latent Thinkings”.

The words “Be careful, it’ll bite you” stay as the words until after you were actually bitten =

Then, it will be imprinted into your subconscious with a pain, and “Be careful” become part of

your “Latent Thinking”.

[]

This is the very reason why actual practice or experience is so important to our life, and what

Lord Buddha said “Don’t believe  what others said but think yourself”

(better still through experiences).

—— (One of my Kinetic Sculpture “Cupidon / Archer” which was made mostly discarded material

—— I’ve picked-up, such as aluminium angles etc.  Except an Air-pomp (yellow one) I bought.  

—— The motor came from a Cooling-fan ) (Moving image is in youtube —> Click right column)

—– through experiences since my childhood, I knew, such as an aluminium angle is so useful

to make a structure, or such as a discarded printer contain very useful motor etc. = I collected

and stashed them in my room = hence made mountains of junks. So, when like this unexpected

situation occurs, I have to work hard to shift the boxes.

—– bad still, it’s an unusually hot summer.

Close-up Lens on EF-Macro Lens

Well, those top two photos were taken by Canon EF Macro 100mm F2.8 Lens alone.

This Macro lens has internal focus system and it will be focused down to the life-size.

 For general macro work,  it is convenient to use though, for me,  life-size is often just

not close enough.  So that I specially made additional Proxer / Close-up lens my self.

As I detailed in the post, By using the Proxer, the Lens can close to  x2 size, and

in addition, it creates almost phenomenal out-of-focus Bokhe.

The Bokhe created by this additional lens looks almost like Air-blush Graphic work.

Still, since this Proxer was made out of the front element of a Zoom Lens, it got double

lens Achromatic construction, no Chromatic aberration was appeared and the focused

image is quite sharp, corner to corner, even when the lens aperture was fully open.

All those photos, except top two,  F-aperture was set to F2.8 and the Camera was

set to AV mode.  Auto focus does work though, as the nature of this kind of

close-up work, I used manual focus.

Ultra heavy Proxer — Close-up Lens from TV Zoom

Those photos were taken by Zeiss 85 mm F 1.4 lens, with my handmade Proxer was

attached to it.  The Proxer = Close-up lens was  in fact, a front element of a Canon

TV-Zoom lens which I’ve cannibalized from a broken lens.  (hence cost nothing  😉 )

As the original lens was a very expensive TV  lens,  it has a very high-quality

Achromatic lens.  ( Even ED glass may have used in its construction.)

In most of the case, it is not very difficult to disassemble the lens —– in this case,

after unscrew 14 small screws, the front Lens was disengaged from its focusing helicoid.

—– then it was glued to a 67 mm filter ring.  (filter glass was removed beforehand)  

Front-element of this lens works as a close-up lens, hence with 85 mm lens it act like

a life-size Macro converter.  —– And with large 1.4 F-aperture, it gives very shallow

depth of field. (and very big Bokhe ! — Still, the focused image itself is quite sharp ! )

——(Metric ruler was shot in 45 degree.  Left: F1.4  /  Center: F2.8  /   Right: F5.6)

Though, this 3 cm thick solid glass in a solid metal helicoid is really heavy, almost

the same weight of 85 mm lens itself.   😀 

(The photo above :  Left was taken F1.4,    but Right photo was F5.6 )

(In those photos, look at how the single hair of fluff was captured on F 1.4  

= Please click and enlarge twice)

As you can see from the photos above, off-focused Bokhe is a bit too much for

most of the people’s taste though, that is what I’ve been after.

(This effect couldn’t be mimicked by PS ! ) 

—– to get this effect, I tried many Soft Focus lenses, Filters, Pinhole Photo,

Double-density Pinhole, even Double Focus in Double exposure.  

But there is no sharp core in a Pinhole photo, and the Double exposure has

the trouble to keep the subject exactly in the same position etc etc.  

= After many many years of attempt,  now I think, I got what I wanted.  

Only a problem is, this TV-Zoom Proxer gives only life-size close-up image.  

May be I need to find another lens which got longer focal length.  😀

Still, it’s a start.

Ultra Proxer — Recycled from Old zoom lens

Proxer is an old name to call Close-up lens which attach on front of the lens.  

The lens I’m talking here is a front lens element  I’ve scavenged from an old zoom lens 85~210 mm F 3.8,  sold under many different names —– the photo was in the previous post (first photo, Front lens was near the left end).

Most of the close-up lens consist simple convex, single meniscus lens mounted on a filter frame.   Same idea to put a magnifier before camera lens and take close-up  photo.  It was convenient to have a small adapter lens to take closer picture, as in the old days there was no such things like a macro setting on the Primary lens (Standard lens).  

—– To make a high-performance Proxer,  I did some cut and bonding works with epoxy glue, which was worthwhile to create a treasure out of junk.  🙂 

Photo left :  Don’t hesitate to hack-saw a lens barrel.  Once disassembled and the glass was removed, even a precision optical device, is a piece of metal.   = What it used to be is only in your mind.  On this moment you are dealing the work to create something new.  What required here is a careful but very simple and boring push and pull work.  😀  

Center photo :  To the front lens, hack-sawed front barrel (which got 58mm  filter screw )  was screwed back and a filter ring was bonded to its rear side with epoxy glue.  

Photo right :  The finished close-up lend was attached on the front of the Canon EF 100 mm  Macro lens, which also has  58 mm filter size.

You might be wondering,  while having macro lens already, and having a skill to use the lens in reverse etc.  = all sorts of close-up trick, why do I need to have yet  another close-up lens. —– well, all of my Macro lenses were down to the life-size, in other words, they take a picture of  36mm x 24mm is the closest.  I simply wanted to close a bit more.  (My attention tend to go rather small things.  🙂 )

—– And a real intention was to have much more exaggerated out of focus Bokhe.  (I’m tired with clear images which is everywhere and too easy to come by today.)     

Photo left :   With this close-up lens, when the master lens,  100 mm Macro lens was set to the infinity,   a small dole (36 mm tall) looks like this. (taken F 2.8)

Center Photo :  With close-up lens, when the Master Macro lens was set to the life-size, it produces  x2 larger image (dole’s head is 10mm).   Have look the Bokhe in F 2.8 = max open).  (This Bokhe is quite close to the Olympus Zuiko 50 mm F 2 Macro lens ! )  

Photo right :  A small beetle who happen to came to my room (it’s too hot these days,  the window was fully open) this photo was taken with a bounced flash-light with F 11.

Unlike most of the Proxer, this home-made close-up lens has double lens chromatic structure,  and fully coated. = Think, a cost of common cheap Proxer, and a Front lens which is the most crucial part of the lens structure in a  zoom lens.  

= Difference of quality is obvious.     As you can see it in those sample photos.  

A photo of a moth parched on the wall in my room, taken by EF 100 mm Macro with the handmade Proxer. = With F 2.8 the depth of focus is really shallow still, in the focused area, the image is very sharp.

This is a test shot of the screen of a Tablet (a photo of my umbrella).  This close-up lens maintained very high quality of the image = Very even, corner to corner.  And this is at F 2.8 ! (See details, by click it, and again)

Left photo is Macro lens alone and about  1/2 size.   Right photo is, with close-up lens but Master lens was set to Infinity.   Hence this combination can take photo from infinity to  1/1  and with this Proxer to  x2.  (By the way, Canon 5D mk-III has dreadful red-color cast when ISO was set to 6400.   In AWB and in any setting.  Though, at  ISO 100 much better.  = See the photos below)

(Photo left :  5D but Mk-II.   Photo Right :  The ISO setting was  100  = Much better !)(Those are hand-held photos = only for Color reference.)  To be fair,  I show you the photos by Nikon D810’s color  in similar setting.

(Photo Left :  Nikon D810 — ISO 3600    Photo Right :  Same but ISO 100   Both with Micro Nikkor 55mm F3.5 — 1/2 )

Higher ISO setting mean, very low out-put of image sensor has to be amplified electronically to its limit.    While amplifying to such extent, still linearity has to be maintained, while the out-put of each BGR may not having exactly the same character.

= Can of warm is opened.  🙂   In the same time, higher amplification also amplify the noise as well.  

—– I admire and praise  the people who managed it and brought the benefit of very high ISO setting even if it was not (yet) perfect.
