500 mm Macro lens ?

The other day I tested an 800mm Mirror lens of which my friend just obtained.

In fact it was a gift from his Daughter.  Lens was for Canon DSLR though, funnily enough

he got no Canon SLR.  —— that’s why I was asked to test, whether for a sake of that lens,

is it worthwhile to buy a camera body.  🙂     These days, people seeing even a small compact

camera started to have extremely high zoom ratio, such as Panasonic’s  x60 zoom

(equiv’ 20 ~ 1200 mm)  they no longer “fear” long telephoto lens.

—– That lens was (amazingly !) good.     So, he is going to become a bird photographer.  🙂

I hope him to become an expert of  “800 mm” lens and capture a lots of bird photos.

As a matter of fact, I got a Mirror lens too, but not  800 mm, my one is  500 mm.

“Naturally”, not very often used though, it was a Tamron F8 Mirror lens = once dabbed

as the second best mirror lens among the 500 mm mirror lens after the Zeiss.  (mind you,

Zeiss Mirrotar 500 mm carries a price of  5 million yen —– but Tamron was 50,000 yen

—– I got it in second hand for 20,000 yen.  😉 )

Not just sharp, Tamron 500 mm was designed to produce good close-up image as well, 

hence its closest distance comes down to  1.7 m and able to take  x 1/3 close-up !

This is a clopped part of the photo. Depth of the field is so shallow still, not too bad isn’t it,  

considering it was nearly  2 m away.    (Can you imagine to look into the reflecting pattern

of batterfly’s eye from  2 m distance ! ) —– (Only when if we could manage extremely

critical focus under F8  darkness of view-finder ! ) 

( Fish-eye photo was an extra —– just for fun.  😉 )

Another trouble is, because of the angle of view is less than  5 degree = quite difficult

to know  “Where AM I watching ?”  especially, when the image was out of focus.  😀

As out of focus Bokhe become funny ring pattern —– you may hate, or some time

they looks more decorative. —– it’s a character.    It could be a good fun to play with !

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.  😀

 

Slide Duplication / Digitization using Flash-light

They are the samples, which were Digitized on fluorescent light-box = I talked about before. 

But photos above were digitized using a TTL flash-light.

( They are in large size = click to enlarge and see the details (but ignore the dust ) 😉

It’s not too bad in highlight tone. ( in the shadow, some noises due to “Brighten-up” )

If anybody visited here twice, you may noticed that the photos are different from before.

—– I’ve changed them, in fact three times as I was not happy with the color of Dupe. 

What I wrote about [Home-made Light-box] —– as a Slide-viewer, it was correct though,

to use it for Duplication was wrong.   Color was far from ideal = in fact, dreadful. 😀

[]

I tried to tinker the color temperature etc. still not suticefied, and tried to use LED light

though,  fundamentally fluorescent light and White LED has the same characteristics.  

Whitish color of LED was emitted by the mixture of fluorescent compound, excited by

LED’s near UV light = same as the Fluorescent light tube.  Since it was produced by a mix

of BGR light, its light spectrum has the typical light-spike from its chemical, hence color is

never perfect.  –—- on the end, I came to the conclusion = it’s better to use a flash-light =

its Xenon discharge light which has a continuous light spectrum is much more natural.  

Unlike easily fooled human-eyes, an image sensor in a DSLR pick-up those

peaks and the spikes and produce wrong color which is harder to eliminate.    

 

To use a flash-light for Slide-duplication is not a complicated business.  

Just place a flash under the white perspex (may be 4″ / 10 cm away). —– I cut a 2″ (5 cm)

square hole in the center of 8″ high card-board box then put white perspex on top, and placed

a flash-light inside.  (of cause, flash is aiming to the cut-out hole straight.)

I put some layers of white tissue over the flash face to diffuse and reduce the light.  

I used Canon 430EX-II in the TTL mode but on -1/3 setting. (For High-contrast original, expose -1

and brighten up with after process might be better)  Flash and the Camera was connected by

an “Off camera cable“.  With this set-up, the exposure will be controlled in TTL though, to make

it a bit brighter or darker, it is easier to use a flash with manual setting (with minimum power

setting ) and adjust the exposure by changing F-aperture or ISO setting, as it can be done from

the camera side.  ( To change the setting on the back of flash is more awkward.)

While testing this, what I noticed interesting was that a dupe made by D800 with HDR seemes

not much different from a dupe made by C’ 5D Mk-III with flash-light (only one exposure) of

which the shadow was brighten-up by common photo program. = Canon’s image sensor and

their processing engine seemed to have wider Dynamic Range in the first place than Nikon.

(To see the comparison in this post.)  To be fair, this matter needs to have more critical test.

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 !  )

Hand-held Photo for 1 second

This photo was taken in a church in Schwetzingen, Germany when I visited and listened  

hundred of Pipe Organ in Europe.

As far as I remember, this photo must be the best usable Hand-held photo (which got an

evidence), in my entire life.  —– how can I say this ?  =  The film was Kodachrome  ISO 25.  

The lighting condition like this = if it was ISO 400,  1/30 or 1/15,  F2.8.  —– just count on

your fingers, it became  1/2 ~ 1 second for ISO 25 Film.  But the lens was Pentax  17 mm F4.  

It was in deed 1 second F4.    Please look into the mirror above the organ key-board. =

The image in the mirror was me holding camera = no tripod.

Still you can read (well more or less) the music score.

Not too bad isn’t it for Hand-held for one second ?

—– (Knack to hold the camera is,   1) Close armpit and put elbow solidly on the chest.

2) Don’t push button with pointing finger alone but do it as if you are squeezing all the

finger inward.    3) Relax, never been tensioned.  Just hold breath and release the shutter.)

(Because of an Organist who is facing the key-board, hence couldn’t see the progress of a 

mass service behind of him, it is necessary to have a mirror there to see the timing.)  

—– Well, it was a long time ago,  when I had a muscle.   😀

Home-made Light-box

Whether you believe or not, this is my Light-box.   It was made out of a Japanese cookie’s

wooden box.   Into the box, I put  a small fluorescent tube and a mirror board under the tube,

then covered with white perspex = So, it became a Light-box.  (So easy and cheap.  😉 )

In ostentatious principle, the light-box should have a Print organisation’s standard light souse,

5000K etc. though in practice non of the so-called Natural Light fluorescent tube got perfect

color balance anyway.   And all the light-box in the market were too big and heavy.  

I wanted to make it small and easy to carry, since non of my client has got one as they are just a

business office, not like an editorial room of a publisher.  When I deliver the photos of the

assignment and to show the transparency to them,  I needed to bring my own Light-box.

[]

Of course, a Light-box “was” an essential tool to a “Film” photographer, but not only that, it

is a very useful tool in general.  When I needed to analyse electronic circuit, I used a reverse

print of circuit track and a photo of component side, two prints together on the Light-box to

see through the connection.  😉 —–  And this time, I used it to copy the old transparencies.

Those photos were taken at the Spring Festival in Seville in Spain.  (1974 ! )

On the duped 35 mm Kodachrome ISO 25 (my regular film then) apparently lost some tone

and I may need to refine more though, still it is usable for a net-communication.

—– PS :  (Usable but, since I was not happy with its color, I made another copy using

flash-light instead of this fluorescent light.  😀 —– I’ll write about it soon. )

I can not stop imagining, these young  Guapa Chiquita now must be the good granny.   😀

They must have had a joyful life.  (Good dancer has less worry.  😀 )

———- (This is the Pipe Organ of the St. Michel Church in Hamburg, Germany.  

———- Taken by Pentax 17 mm Fish-eye lens on Nikon FE ) 

For some high contrast image, even a dupe on Home-made cheap Light-box, using 5D Mk-III

with 100 mm EF Macro is not too bad.

 I’m really happy, after almost 40 years Kodachrome retained its original color.  

(you may say “So, What”  😀 )

Home-made Light-stand (2) — Copper Clad Cable Spiral Lamp

This Spiral cable Lamp was the earliest I made in England.   While stay in London, I used a

Film Labo’ where many Japanese photographer were taking their film to be processed.  

Photographer is the observer of the world and the human life.   And the people who is

developing  their films are yet another kind of the observer.  —– By watching the subjects

in my film, the owner of the Labo’ seemed to have noticed who I am, and asked me  

“Do you know electronics ?”  “Yah, a bit”  “Do you know about this machine ?  Can you repair ?”

—– It was a hefty spot welder.   Hefty because of it got really hefty transformer inside, still

its structure is rather simple.   “OK, I’ll check it with my tool tomorrow”. = Next day, I found

the welder’s brake down was caused by a micro-switch in the timer controller and I replaced it.

= Here, working again.   The owner was very impressed,  not only a photographer carrying a

test equipment but actually able to repair the machine.   (He knew, knowing and able to do is

not the same thing.)   “OK, in exchange, you develop those  10 films free”  “Oh, sure”  

I like a kind of relationship which doesn’t involve a money =  I help you, so you help me.

And I started to use their small room in their studio as my office and in exchange,  if

anything repair kind of needs happened, I’ll help them.  Almost like an in-hose engineer.  🙂

(That’s how I got an experience to deal with 2500 V,  5000 WS studio type flash etc )

But to carry out some repair, in a awkward corner of the big studio space, or under the film

processing line,  I needed to have a work-lamp.  I made this Spiral Lamp of which all the

materials were piled up in a corner of the studio where used be a huge vegetable storage

in a corner of  “used to be the Covent Garden Flower and Vegetable Market”.  

(So, I know the Before and After of the Covent Garden Market !  🙂 )

[]

Copper Clad Cable is not common Japan where the main voltage is 100 V.   So, I first seen it in

this country.   The cable was covered by a copper tube hence it is quite solid and fire resistant,

still having certain flexibility or able to bend.  Most of work lamp was wire caged to protect

glass light bulb = so, I got an idea to use this cable itself to make protective cage around the bulb

—– then wall mount switch-box was fixed as its base. (Socket was fixed to the end of the cable

using Epoxy glue).  —– this is yet another minimalist’s approach though, all what we need are

there and perfectly functioning.  It may looks odd and a bit awkward to change a bulb though,

it worked perfect for my purpose.   Is there anything  wrong with it ?

[]

PS :  A quite few people, even the electrician who came to my room to re-wiring and the readers,

questioned me, how I could make the Spiral so neat ?  = Cable (Piro) was first close wound around

a gutter-pipe about 8 cm, then it was pulled and expanded.   Then both end was bent to the

wanted shape.  (Of course, the both end, the copper tube was peeled off and the conductors =

two cable were covered with proper  insulator sleeves and made proper electric connection.)

Though, I wouldn’t encourage the reader to do this kind of work, unless the person got enough

skill like a qualified electrician.  To play with main power is a very dangerous business.  It kills.

Home-made Light-stand (1)

This is one of my home-made Light-stand, second simplest one, which I found in a box

I’ve stashed it away 20 years (?) ago. (the most simplest one was using a bent single pipe.)

Light housing was made out of  7 mm pipe of which the top was rounded by tapping and bent.

Photo Left : Originally it was using very small tungsten bulb for an indicator though, those

bulb doesn’t last long, not mention a problem of heat-up.  

So, in this occasion, I changed it to a wite LED (Photo Center) .  In this kind of design, the matter

is the “Adjustable Pipe Clamp” = here they were made using shallow Aluminium C-channel,

bent to U-shape.  = One screw can loose and tighten everything at once. (Photo Right)

Thanks to LED, it can light up pretty long time from three AA batteries hidden under the base.

[]

Don’t ask  “What is for ?” = You may not ask a painter  “Why you sketch this land scape ?”

To see an aluminium pipe and think how to use and to make them into a certain shape and

appropriate structure is a game of creativity.  —– simply it is a fun.  🙂

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. 🙂 )
