Shallow Focus — Pan Focus (with tilting lens)

Some sharp eyed reader quizzed me, the photos of Dandelion seed are odd on previous post.

Very good eyes and the knowledge on photographic image !  —– So, I reveal the trick behind.

There is no such things [Lens Rivers Adapter for Canon EF lens].

But it is just a lens mount ring with a male filter thread on the other end.  That’s all.

If Canon is not selling,  make it ourself.   Why not  😀

Anyone can put two together with glue !   What’s the hands for ?  (not much brain needed ) 😀

But to make it,  I wouldn’t just glue together straight —– I glued them in 40 degree in angle !

(I wanted to make it 45 degree though, it was too much, and caused image-cut off = I had to

compromise though, the photo is using the image to the edge, quality became pretty low )

—– With this tilted lens, Focused field is 80 degree in angle to the camera = much easy to have

a light and able to creates Pan-Focus effect.  (Photo above, Left)

But, when it was tilted to the opposite angle,  focused field is perpendicular to the object, hence

it shows very shallow focus and exaggerated off-the-focus “Boke“.  (Photo above, Center)

[]

In fact, I’ve been using this Pan-Focus effect since I created Yoshi-Handy and Conica-Tilt

40 years ago, long before Canon TS lens. (You can see both cameras in an old post = Link here)

unlike this Tilted Revers Ring on 5D,  Conica Tilt gave a Pan-Focus from lens front to infinity.

———————- (Without the Lens lock pin, lens was secured by a crow inside, operated by the top-left round lever)

———————- (Incidentally, the Iris was automatically operated by a solenoid on the moment of shatter release)

To have a pan-focus to infinity in one shot, one side of the lens has to sink into the camera body,

so that, the camera front had to be Huck-sawed,  giving a margin of lens movement.

(See the inside detail in a photo right —– to do this kind of work = to prevent the camera

mechanism jammed by the metal dust, all the mechanism had to be removed

= it’s mean, camera had to be completely disassembled and made it to an empty shell).

[]

With this modification, lens can tilt 30 degree max, and one side of the lens is effectively

extended 18 mm = with such extension  to 15 or 16 mm lens meant, it is effectively

life-size macro !   (As I was an original member of  PCW (Personal Computer World Magazine,

until they were bought up by I.P.C) this tilting lens camera enabled to produce a photo 

“Foreground  is a CPU chip, and background is the computer company’s building, in one shot”)

[]

I’m planning to make yet another lens tilting camera using Canon 5D body (though, I have to

do its hack-saw work without disassembling the camera body   😀  )   May be I Just Do It. 

( It is a Zen in ACTION !   With open-minded way, there is no prohibition.  Only, Do the best  :-))

This is a photo of a Canon EOS Body.   Although this is the Body of EOS RT,  as most of the

camera designer in the same company are using the same layout of  the mechanism, even

using the same frame die-cast,  (since the position of Switch, lens-lock-pin are all same)

it wouldn’t be so different on 5D body.  = to modify the body to tilting-lens body only needs

to remove the metal frame marked between yellow stickers. ( —– in theory.   😀 )

[]

How shallow the Focus can be

This is yet another attempt to create  [Not necessary sharp nor pretty photos] and in here

they are the technical samples.

Lens used was Canon EF 28mm F2.8 but mounted on Canon 5D with Rivers Adapter.

As electronically there is  no connection to the body, F-aperture was fully opened  F 2.8.

And this is not purposely designed Macro Lens  (Macro Lens was designed to give the best

performance at  1/10  of Magnification ratio = if it was 50 mm lens, at the distance of 50 cm

to the object), with fully opened F-aperture, image quality is no way near to a sharp image.

With popular belief, you may be thinking that the Wide-angle lens has deeper depth of field. 

This is only true to the Object side, but not to the image side. 

Think, —– 50 mm lens needs to move 5 mm forward from infinity position to focus 50 cm

distance, but for 28 mm lens, from infinity to 28 cm object (at 1/10),  it needs only 2.8 mm shift. 

In other words, if lens was used in reverse direction, depth of field would be even shallower,

and the out-of-focus image, “Boke” would spread much wider, as you can see in the photos.

But, whether it has any significance to the photography is a matter of individual taste.  😀

The reason why I’m showing this is, this optical effect is a sanctuary in the photography,

away from a hand of Photoshop,  unless a photo was completely repainted pixel by pixel with

human brain.  Make a photo looks sharper is easy but very difficult to reproduce 3D “Boke”.

If anybody think otherwise, Please send me the Sample = Before and After, created by Photoshop.   😀

What is Natural — Tea-bag Story

Many years ago I needed to filter out crystallized residue in a photo-chemical solution.

On that time, I improvised a paper of a tea-bag = it is quite strong not like a tissue paper, neither

it would disintegrate in a liquid.   (If it was in my school time, I could have proper filter paper for

chemistry, and till decade ago, a blotting paper was in a stationary shop, but not in these days. )

—– anyhow the matter is neither type of paper or chemical solution, but

what I found in the contents of a tea-bag = powdered tea of cause. But something

annoyed me was, I found looks like a thread or a sort of fiber sticking out of the

tea powder. It can be a broken jute rope or a sack, or it could be even a fiber from

a cow-dung, came to a floor stuck to a sandal of worker.

[]

Before the invention of tea-bag, the powder or dust of tea, flying out of tea processing machine

was only recycled in a small scale as a give-away to the poor people working there.

But when somebody got very very good idea to utilize those dust, put it into a paper

bag and sell it as Tea-bag, the more convenient way to make a cup of tea, then the

dust was collected using a vacuum-cleaner, hence the dust on the floor as well.

—– (I heard this story, first from a man used to work in a tea packaging factory, and again from

a daughter of an English manager used to be there )

Still, to design an automated machine to make such a bag without using glue was a good effort, but

it was a bit expensive way= hence, to make a round flat tea-bag with one stump process was

another step to make yet more profit = insatiable appetite to satisfy their greed.

[]

There was a report, about the coming food-shortage and “Then, why not eat the insect” story

—– in the story, there was a statistics “the average person eating so-much-so amount of

insects comes with food without knowing”—— yeah, I’ve noticed this many times, while

eating such as vegi salad, I had funny taste.   As I used to collect the insects to make a collection of

specimen, I knew a certain insect gives off particular smell. It was that kind. But, anyhow it was

too late and so far there wasn’t any detrimental trouble I’ve ever had. = So, it should be OK. 😀

[]

In the same context, is there anybody ever thought about, —– in the processed food such as

mince-pie, fig-role or jam kind of milled fruits, packed into a sweets or in a jar, what is in there ?

Are you expecting in a food factory where the one end, truck lord of fruits was through into the

machine and on the other end, packed jam is coming out in a jar, whether individual fruits was

inspected for insect and rejected one by one ? —– (So that, there is a law giving the allowance

for such kind of food can contain so-much-so number of the insects)

[]

The question is, what is natural ?

It is not an issue of credibility of the manufacturer, but ourself.

= If we are believing the quality or its purity

—– Isn’t it our wishful imagination or indulging illusion ?

After all, in reality, nature is not necessary friendly, or the conditions of our life may not so ideal,

we should better accept it as it is, instead to project our idea and create frustration.

[]

To become aware who I am (of whom never be perfect or ideal) is what we need to

have, as the first step to become a bit wiser. (not mention to get enlightened 😀 )

To accept or appreciate a hint of cow-dung in a tea, might be the crucial step

to be a broad minded Buddhist 😀 😀 —– (Do remember, this is the way, how our

immune system was developed = hence, it enabled us to live in this bacteria, virus infested world

= dirt is our part of the life 😀 )

So, keep yourself reasonably clean for not to have too much bacteria, but in the same time never

become compulsory cleansing fanatics. Happiness lays in between = in a so-called Middle Way 🙂

Enjoy your happy day, and a nice cup of Tea as well.

Win win – Musashi the Sword Master

There was the most strange quote of Sword Master Musashi Miyamoto.

When he was asked what is a secret to keep winning the fight, he replied,

“ Never fight with a man stronger than me” —– !

( I wasn’t there to hear this myself, so I’m not sure whether this quote is true or not though,

from the level of Zen he reached, this word sound quite likely his own word. )

[]

Enlightenment in Zen liberates one’s mind = Liberate mean, free one’s mind from

all the restriction and the bondage of the ideas.

Free from pretence, rules, stereotypical beliefs even one’s own Ego.

So that, here is a contradiction, why Musashi needed to win ?

Why he needed to avoid to fight stronger opponent ?

But, before that, there was a preceding condition, why needs to fight ?

To seek a fight is driven by an intention from the Ego, Greed for the fame etc etc,

but once he reached to the level of the Enlightenment, he no longer had an impetus to fight.

( But Sword Mastery is not came from the will, but instinctive body reaction = if it

was needed to react in the situation, he could have done without having a will to fight

= it was not him fight, but the Dharma does ).

So that, once Musashi reached to this level, even the other sword master as good as him dear to

challenge him because even if challenge was successful, fight would cost a limb or two = a life of

sword mastery would be lost for ever = no point to challenge Musashi — and it never happened.

[]

Still the remaining question is, why Musashi uttered such words to spoil the game.   😀

It was because, what the Zen and its natural choice = Middle Way was.

Once enlightened, to cling the idea of Zen disappeared too.

(Conscious idea doesn’t need to be there because everything were controlled unconsciously).

So that, on the occasion, chattering with young novice, what situation required (= a task on front

of Musashi, on that moment ) was to have a good, cheerful conversation.

Why needs to be so serious.  He just took a Mickey out of serious novice.

(To his eyes the people in Sword Mastery or Zen seemed more like a caricature figure then)

Go, Middle way.   So that, the life can have much more fun. 😀

Relax !

Delusion or Common Sense

In a good sense, we human is a very creative people by which it had lead the

advancement of our civilization.

In the same time we are the most deluded creature on the earth.

What is common between creative and deluded is, its thinking process, think beyond the fact

which was known or widely accepted, or believe to be exist, or true.

Our cognition and its assessment of the fact are always following after the event or encounter.

To compensate this time-rug, our judgement is projecting time ahead.

In another word, speculative.

—– When you see a cockroach running on the floor, you wouldn’t hit the place where it WAS, but

look under the bed where it has disappeared. —– and put a cockroach trap expecting if it comes

again, the trap should catch it.

[]

Audiophile is the people who is the most speculative kind of people apart from the delivertive

or commodity trader 😀 —– of cause, they would say, it is not a speculation but

the fact of what their ears hear.   Here, fundamental speculation is that they are

believing their ears are correct. —– Once I was an audiophile (in meager scale 😀 ) hence,

I tested Audio-amp, Class A, B, AB etc with different transistor etc. ( On the end, I was convinced

that it would be fruitless attempt which never able to achieve the quality of live music = I decided to

listen the original sound at the original place where the recording was made = so, I came to Europe.)

[]

Time to time, people asking me to repair their audio amp.   In most of the case it was a kind,

a professional repairman has forsaken, such as a transistor had been exploded hence the name of

component was lost (and it would be too expensive to ask the maker to give a service, if they still

exist at all, but often not — in such case, analyze the circuit and find what to replace it best)

So, I have ample experiences to see the realities in the audio amp design = how far it is, from

the belief or deluded wishful thinking of the people buying it. = It is a fraud.

( Go too deep into the technical detail is not in an aim of this blog. So, I’ll show a point in a level of

secondary school common sense —– I think you can understand)

——————————————————————————————— (Photo right/ Yellow mark pointing burnt out track )

A photo above is said to be a car audio amp for sub-woofer speaker. Apparently, it was solidly built

hefty amp which is saying 500 W ! — Who believe it ? (obviously a man who bought it did )

To use an audio amp in the car, the power is a car battery which is 12 V.

Every body remember, the Ohm’s Law which I learned in the secondary school Physics, they are

few lines of very simple formula like as [ R x I = V, hence V/I = R and V/R = I ] V=Voltage,

R=Resistance, I=Current.   And in addition [ I x V = W ] W=Wat.

(In fact, it is more of the definition. The unit were defined as it is. = from 1 V source, the current

run through 1 Ohm wire was defined as 1 A —- I admire the scientist who measured then).

[]

As a car audio amp, the supply Voltage is 12 V.  = To out-put 500 W, the amp needs to draw

500/12 = 42.6 ( A  ampere ) —– though, a fuse fitted was mere 15 A.

Assuming, the amp was able to draw 15 A without blowing the fuse.  = 12 V x 15 A = 180 W.

—– within safer operation, it may not more than 150 W.   Then, to consider the efficiency of any

electric devises, they never be 100 %.   In a case of audio amp = every body knows, the amp is

getting quite hot = the power was wasted to make heat = and that was why this amp has such heavy

heat-sink and needed to make it so solid. But this amp is designed rather new Class G like design (but

without having additional power supply line) —– so, the out put power is 120 W  in its best.

—– still the person who was using this amp has been enjoying to be a proud owner

of what he believed to be 500 W car audio system.

[]

It is more like a religion.  It was out of school level common sense though, is it a matter for him ?

—– Like a people, believing so-called power of crystal with pretty happy feeling, “what is the truth”

may not be a matter for them.   Feeling happy might be more important. —– Is it ? ? ?

Pretty picture on a sham-doctor’s beauty potion might give better dream than the truth in reality.

After all, we human is a people living on the dream.   Even a placebo effect of false

belief still able to give some positive results.  What’s wrong to be deluded ? ? ?

The question is should I tell the truth what is the real power of this Amp ?

Keep him happy or make him wiser ?   (Good question ! )

Thought on MARATHON — SUFFERINGS

Tomorrow, tens of thousand of people will run for London Marathon.

Quite few of my friends did it and till some years ago, I was thinking I’ll do too though,

I’m becoming aware, better not.

( I can invent hundreds of the excuse not to do = it’s mean to think about itself is utterly a waste of

time.= So that, in accordance to my Zen Moto [Just do it] => Just think not. Ha ha ha 😀

Therefore, in my peaceful mind — Marathon ?  What Marathon ?   What a nice day !

[]

Why people run for such enduring action which is not even their imperative, which is,

some said useless action.  = Of cause, some are running for the Champion Medal and some are running

for Charity though, bast majorities are running for a sake of just running, or even for a fun.

What is a fun while giving 50 km or so torturing, punishing task to the own body ? —– of cause, as

I used to be a member of the Alpine Club, I know what it is, as we did similar training and above all,

we did pretty similar body punishing long walk in the mountain, often carrying 40, 50 kg of lord on

our back. —– and we mountain climbers were always making joke

“ What silly things we are doing 😀 ”

[]

Then give a thought or two. —– ? ? ?

Have I, have we ever had an easy life ever ? —– We, the greedy creature, the human,

always assess an action in comparison to the gain though, is this kind of view true ?

For a sake of convenience and to have an quick answer, we Buddhists having a tendency and good

excuse to end the argument, we have pretty nice story to convince ourselves into contented, which

called Enlightenment 😀

—– See this in reverse. = Need to have an excuse to have a peace of mind is,

because it is not in a peace at all isn’t it. 😀

[]

In Lord Buddha’s teachings, life was defined as SUFFERING (how nice). Yes in deed, this is true.

So, a training is the training for this unavoidable enduring life. = training for the Marathon but the

Marathon itself is a training to face a situation in the life.

June in every year, we members of our High School Alpine club had a special stamina training for a

preparation for a summer climb while carrying 40 kg of stones to a 900 m high mountain top,

starting 6 o’clock morning, reaching the top about mid day.

It was on a ridge called Baka o-ne in Oh-yama, west of Tokyo. Why it called Baka o-ne, Nut’s ridge

is, it is just one continuous boring climb, no respite = makes anybody just fed-up.

[]

While carrying 40 kg of utterly useless stones, I cursed every single step “What am I doing.

How silly I am. Ok, on the next step, I’m going to through this stones away and shout to the leader

“ Kill me here, I’m out” — on the end we reached to the top AND came down with empty ruck-sack,

that was all.  (Since many clubs are doing this many years, the mountain top having tens of tons of

round shaped river stones, which makes innocent walkers just puzzled.  “How come ?” 😀 )

( Soon or later, I tired to complain = after all, to join the club and came to the mountain was my

choice.  I’ve gained a kind of contemplation [Just walk] otherwise I shouldn’t have born to this

world. — And I continued this, while keeping Mountain shelter as a volunteer, we had to carry-up

the food staff for the lodgers of up to 300 people a night, without receiving any money, far from it,

we had to spend our own money to get there  Kita Yatsuga-take.)

[]

Anyhow, the life is the suffering  😀     But, if we have a training while having heavy punishment

to the physics and to the mental strength, we obtain good resilience to a cause of those sufferings.

To over-come the endurance of Marathon, the person gain the proof in the fact, I did.

And this proof gives the person a confidence = I can do, because I have done.

This confidence brings a peace of the mind = Don’t worry too much, it may not

as bad as the Marathon. 😀

So, it is a good news, it wouldn’t be in vain.

Enjoy a running.   Have a good Marathon 🙂

Mushin – Panya Paramita – Dharma (in [Z-band] )

Hidden between the line of funny Cat’s story, the paragraph ;

The stories of the Zen Buddhist communicating with other animal may have

the basis in this phenomenon = silencing the noise of thinking in the Brain

mean, it is to be in a state of  Mushin.

Not in thinking but having a deepest perception of  friendliness in the

primeval Limbic feeling = This feeling is the common language with any

living form.

= Here is a good insight to understand what the Panya Paramita and the Dharma is.

[]

To make the story easy to understand, let’s use a metaphor = assuming the [common language]

quoted above is a kind of signal in certain frequency, to say [Z-band].

Like Internet system, all the Spiritual communication and the information are exchanged through

this [Z-band] channel.

This channel is inherent to all the existences include the all the life form, it’s mean this is the

communication system of the Dharma.

All the life form mean it’s include us too.   Therefore everybody having born with

the Dharma with in (born with a Receiver and Transmitter) hence, the person

should able to receive the signal.

But, unfortunately, because of us, only us human got hugely out grown brain, thanks to the evolution,

our brain and its activity is creating too much noise, and this noise is

masking the [Z-band] signal.

[]

Since we evolved like an “add-on extension” on top, we still retain old system in the base.

The process how we were developed in the Mother’s womb, from a single-cell organism = egg to

fully grown human body, showing this fact.  = (Once, you were a fish —– remember ?)

In other words, we are retaining whole evolutionary history together with its DNA (and memory).

In our expanded brain / neural system, the old part is known as the Limbic system.

This Limbic system is common with another animal.   So that, we (our far ancestor) were

using this Limbic system with pretty small brain.  But, as there was no huge noisy brain then, all the

signal we were using for communication was in the [Z-band]. As all the existences are using

this [Z-band] too, we were able to communicate with other animal and the nature.

Life and the survival was relying on this system.

[]

You may feel strange though, this communication in [Z-band] is existing even in a photography.

In WordPress Blog, such as [draw and shoot] (link here) I noticed, the author, Karen is communicating

with nature in this [Z-band] as her photos are showing it.  Hence, I often commented saying her, her

eyes are the eyes of Zen. = No wonder, her Blog was selected as one of the great blog for Earth Day.

(Incidentally, Radio Communication is using X-band for Satellite channel but not Z-band yet.  So, I

made up a word Z-band = Z after Zen  😀 )

[]

Unlike so-called intelligence and our signal processing system in the current brain, which got only

few hundred thousand years history, this [Z-band] has been used and refined in the hundreds of

millions of years in the history since then the Universe was created.

Because of this, this is the channel, where the information of  Dharma, even the

activities of such as this Planet was broad casted.

(Hence animal can sense the coming Earthquake or foresee the weather).

[]

To listen this [Z-band], it is essential to silence the noise of the brain.

The Buddhist’s practice is a way to obtain this silence = Mushin.  Then, in Mushin,

what we are able to listen is, what Dharma is telling = This is the Panya Paramita.

But this signal is not an abstruct message such as the God’s words, but live broadcast of the

situation we are facing. = It’s like a latest Drive Information system. You can see all the

meter-readings and the SatNav information of trafic condition though, it wouldn’t tell you

the destination or Philosophy in driving.    Read it and what to do is up to you.

[]

Lord Buddha’s teachings are all about “How to get it” = the way and the Practice, not an

abstract answer.   The Answer has to be found by the person = [Think yourself], as it is different

in situation by situation, person to person, as each person has own Karma.

To see its situation and respond to it,  live in its moment is the matter.   It can only be found

by [mindful clear eyes] of the person, obtained through the learning. —– This was why

Lord Buddha didn’t answar “General view or belief” like what the Dharma is = Because

the Dharma is a moving mechanism, working in its rationality ( of which we only able

to analyze its small corner, not in its total dynamics, and WHY) = The important matter for us,

is to see the Fact in meter-reading, not a belief or a fancy illusion which exist only in the mind.

Lord Buddha didn’t teach anything supernatural.  But, this Panya Paramita in the [Z-band]

came to the edge of it.  For him, it is the FACT though in the same time, he knew it is audible

to only few people who can hear = no need to explain to them since they knew it, but impossible

to make sense of who couldn’t.  It’s like a pain of Kidney stone = only the people who got it knew.

This was the reason why he taught only the way to get it ( I mean not Kidney stone  😀 ). 

And this was what

Lord Buddha found and taught.

Humble Lens (?) for Canon Camera = Pinhole Photo / BGR Tri-Pinholes Photo

You might think the Photo here is yet another bloody Soft Focus lens.

It’s not by Soft Focus lens. —– In fact it was not even a lens at all.

——– ( Like latest  5D Mk-III,  5D Mk-II also has Light-leak or it might have caused by the internal reflection

———  on a shiny surface of a parts.   Canon can say, it is not in a normal use what camera was designed for)

This is a Pinhole Photograph on Hi-Tech DSLR —– ! ! !

You might be surprised —– or bemused ?

(End of this post, you can see  3-pinhole photo with BGR color-filter for each pinhole )

—————— ( Cutty Sark in Greenwich —– Hand held Pinhole camera, F250, 1/15th Second, ISO 3200 )

One of the best advantage of the Canon EOS cameras is, their Light-measuring

function works  without any lens attached on the body. = Light was

measured on the light actually came into the sensor, and the exposure value

was calculated on So-called Stop-down Metering.

In comparison, other cameras are guessing the exposure based on the

information came from the lens, mounted on the camera. Its mean, their

camera was designed to work only with a ROM memory hidden inside of the

lens which gives the information of lens ID, what is the current setting of

focal length on Zoom, F-aperture setting (in a case such as Nikon which allow

you to use an old manual lens) etc, with an assumption of the lens would

work accordingly.  (If the lens was F4 in full open, calculates how many stops

needs to close in this lighting condition.  Canon measure actual light instantly,

when F-aperture was closed, then select the shutter speed).

The reason why other manufacturers are using this design was, to prevent

the use of a lens other than their genuine products.

(The ID of lens would direct a correction program,  such as to brighten up

the corner-fall-off of the wide-angle lens).

——–  — ( Cutty Sark in Greenwich ) ——— ( There was a Cinema Film Shooting at Old Royal Naval College )

On the beginning, in order to cut into the Nikon dominated professional

camera market, Canon designed their camera even capable to use with

Nikon lens.   Hence, in the early 70th, they sold a lens mount adapter to use

for Nikon lens.  (Later, when they gained popularity and their confidence grow,

they stop to sell this adapter). 

The First Gulf war was the turning point for the choice of professional camera,

as most of Nikon were stopped to work, thanks to the microscopic sand dust in

the desert.  Only the camera kept working was the Canon. —– As a consequence,

News Photographers changed to Canon.

Still, the tradition to allow the use of Nikon lens was kept by Canon, since such

as special 2000 mm lens which was made only by Nikon, Canon has to make a

provision for News photographer to use such special lens on their Canon body.

= hence, camera was designed to functions with the lens which has no Canon

ROM memory.  In other words they can work with any lens. 

So that, their camera, even Digital SLR can give enough exposure function except

Tv and Program Mode. = still perfect on AV Mode and of course with

Manual Mode.

Above all, with DSLR, we can check the result on the spot, and change

manual setting or exposure compensation on Av.

( Or, change ISO setting further).

——————————————————- ( At Painted Hall, Greenwich )

So, there is no problem to use Canon with a reading glass, plastic flat lens

(Fresnel lens, which gives utterly unsharp image 😀 ) —– even with

Pin-hole, while leaving all the exposure control to the Camera !

= Just use AV mode and adjust exposure compensation.

(Though, Canon 5D gives only up to 30 seconds on AV Mode, if you need

longer exposure to make picture brighter = increase ISO to higher setting,

or change to Manual Mode.

And if you need to have very long long exposure to make all the moving

things disappear, use lower ISO or use dark ND filter together.

Unlike on color film, the adverse effect of UV light  (which causes blue cast),

doesn’t affect the color on Digital camera.  But never have a direct sun in

the image.  Without having any protective glass lens which blocks UV light,

it may damage the Image Sensor).

————————————————————— ( At Greenwich Town )

And, to do this kind of creative shooting, you need to pay attention to

[Good Common Sense] such as, to use View finder cover to block the

stray light from the back.  

And use good black paper for making Pin-hole, and make sure, pinhole

should be clean round hole with no paper floss messing on it.

And DO MAKE SURE, keep everything DUST FREE. 

Wash your hand before hand.

= a dust particle got onto the Image Sensor is very tricky to clean.

Your acute mindfulness was required.

——— ( Sake of photo, Pinhole was placed on EOS RT body )—– ( To make a perfect hole, it was made on a smaller

———————————————————————————————- piece of thin metal and attached in the center )

A paper with Pinhole, will be stacked on the lens mount of the body by a black

PVC tape to seal-off the stray light.

The Canon DSLR camera has the depth = Flange-back (Lens mount to Image

Sensor) 44 mm, therefore the field of view is the same as 44 mm lens. 

And if you use an Extension Ring and stick the pinhole further away from the

body, effectively it would give you telephoto images.

In the most of the case, (as a fine sawing needle has a diameter about 0.5 mm)

the size of this hole is equivalent of F90. (With a focal length of 44 mm lens,

if the diameter of the lens was 44 mm, it would give effective F-aperture F1,

hence, 44 /0.5 = 88 = about F90)

—– I’ve made it less than 0.2 mm = F250.  Instead to use a paper, I used thin

aluminium panel of a Drink Can, and pierced it with just a tip of the needle.

The smaller the hole, it would give sharper image though, the optical effect of

Diffraction will scatter the light, it can not give sharp image like an optical lens

anyway, but on the other hand, it gives pan-focus. 

(The hole doesn’t necessary in the center = You may put it far side and take

picture always one half, like top-end.  Or to put TWO, to make double images,

or one with color filter and so on, there are endless possibilities,

still cost nothing.  😀 )

(Try it and find new play ground in photography  😉 )

Fuji Soft-Focus Lens

While looking for a Pentax 20 mm lens to use for Macro shot (use it with revers mount-ring

on Canon —– Canon’s 20 mm lens is too big and F-aperture couldn’t be set manually),

Then I bumped to 40 year old  Fuji Soft-focus 85 mm F4 lens, deep inside of camera cabinet.

Yah, yah, I’m still having this ! —– I remember, I used this lens twice = It is my bad habit to

buy strange Camera, Lens, funny devices whether I need to use it or not = still, to see how

it was designed or what sort of things could be created from such junk is,  I should say,

my pleasure. —– (Like £10 broken camera, it is a treasure box of spare-parts)

Any how, to test this lens, I popped out to take picture of  Chery Blossoms. (Yet again  😀 )

Most Soft focus Lens is using an optical aberration = Uncorrected Spherical Aberration, 

which cause the light spread out side of the image, hence giving soft halo around the image

while maintaining the sharply focused core image in the center.  (Though, having inherent

soft image in the view finder, to have sharp focus in the first place is not easy  😀 )

And as this Fuji Lens is using so-called Lotus-Root Iris (having lots of hole in a disc) to

control intensity of the effect, some time the artifact appears in the off-focused Boke image. 

In the photo above, you can see the ghost of multi-hole disc. = this is a sample of dirty Boke.

When soft effect works well, effect is far better than soft filter or grease, as the image has

solid core of focused image.   (With soft filter, everything become soft).

With darker background,  you can see how halo spread around the bright images.

Though, with low contrast subjects, the effect is subdued.  In fact, with smaller F setting,

the effect of aberration become very little, same as even a cheap bad lens can give sharp

image with small F-aperture setting.

These days,  even a Mob’Phone camera can take pretty sharp photos.   Sharp images with

over Photoshoped photos are everywhere, and I’ve got rather weary with them.

Our eyes are not necessary need to see everything in its details. That is why, when sharp-eyed

Photographer showed unknown view or fresh viewing angle, the image surprises us.

So, I found, soft images which shows [the details as if no details are there],  isn’t too bad.  😀

Talk with Cats = What is MUSHIN

Somebody said “Hey yoshizen, you are utterly nuts, how you can talk with cats ?”

—– Quite often, when I saw a cat, I call him (her ?) “wu Nya” 😀

And lower my body or crouch and say “Oide, oide” (it’s mean, “Come, come” in Japanese.)

So that, my friend who happened to be with me, say “How this cat understand Japanese ?”

or “Can they understand Japanese ? Hey, don’t be silly ” —– then, those friend

was surprised as he saw the cat is coming to me and having their head scratched.

[]

So, I said to my friend “Of cause, they don’t know what that Japanese mean.

But, do you know, the cats can read our mind ?” “Oh yes, I know they can”

“So, this is it. It doesn’t matter what language I have used on my rip, but my mind,

in fact deep down to my subconscious level, I’m expressing the friendship message

as the same kin.  Cat understand this message like a mind reading”

[]

If you remember what I wrote in the previous post, you may be confused by this description.

—– “Deal with cat in Mushin”. —– What the Mushin mean here ?

THIS IS the most misunderstood point in the Buddhism and in the concept

of Mushin and the SELF.

Open your mind, don’t think anything, empty your mind, brah brah brah ——.

They are all just the words, only described the superficial appearance and its observation.

Yes it is true. There was no thinking in the brain on that moment, hence it seemed the mind

was empty. —– still, full function of the body is continuing.

Tea Master is making a tea, Sword’s Master is fighting, I was calling the Cat. = all

those actions were carried out in Mushin.

[]

Lots of amateur Buddhists and Sham Monks or so-called Instructors, Practitioners are believing

and teaching that the Mushin is a kind of special mental state occurred only

when sitting and meditating.

—– Forget the Buddhism for a while. (Before talking Buddhist’s mind, you better know what

the ordinarily mind is 😉 ) = Remember what people say “Talk from your Heart”

“It struck our Soul” “Selfless Love” etc ==== You can understand all those words straight,

what it’s mean. = In fact all those words are describing the same psyche in our deep-down mind

= the pure human emotion in our subconsciousness, without any intentional thinking

= away from political, psychological manipulation, self enriching maneuver or egotistic thinking.

People can naturally feel, talk and act without having any those intentional artificial thinking.

—– Where those Thinking come from, and where those psyche described as

Heart, Soul or Pure Human Emotion come from ?

[]

Complexed highly intentional thinkings are all bore out of our highly intelligent Cerebrum =

large Brain.  But Heart, Soul and Pure Humanistic Emotion are come from our

Old Cortex and Limbic System.

(Which is common, even with cats, hence we can shar the same psyche. 😀 )

Mushin = Mind of No-Mind is the state of the brain, when all those Thinkings in the Cerebrum

were stopped (or suppressed, abandoned what ever the word. And an advanced Zen Master can

stop even the process or Emotion in the Limbic System as well). = Still, some subconscious and

basic function in the Limbic System can be maintained and continue its process.

[]

Likewise, the Self with its Self Conscious Thinking together with its Emotion could

be disappeared, still able to maintain the integration of the body and its function.

= Thinking was stopped still, subconscious is aware the situation.

In fact, subconsciousness knows the situation far better, because Limbic system

is directing and controlling all the data flow in the Brain.  The Cerebrum is only

converting some of those data into the words and to the visible conscious.

(This is why the argument, what is the SELF and whether it is exists or not was started.

And the typical Mahayana Expression [It exists as not exists] was invented).

Consciously conscioused SELF is clearly be seen, but subconscious is invisible. 

You can hear my word to a cat “Oide, oide”, but you can’t hear the signal

in [Z-band] channel hidden there.   (Unless you too a cats person  😀 ).
