Evolution of PINHOLE System

Multi-Pinhole-1-001

Till now, I made quite a lot of Pinhole to take pictures for my

Canon, Nikon and invented “Concentric-Double-Density Pinhole,

and Wide-angle Pinhole

On top of those, even Double, Triple Pinhole, Tri-Color Pinhole

— on the end, it’s a mess. = In order to rationalize, I designed a

Convertible Type = Simple Single Pinhole, up-to-4 Multiple Pinhole

and Concentric-DD Pinhole with Selecting Tab, on the Nikon Mount

(Which is easily converted to the Canon) together with Detachable

Wide-angle Lens on front. 

So, the sample images were, Top photo Left = by Single Pinhole, 

Middle = Triple Pinholes,  Right= Concentric-Double-Density Pinhole.

Multi-Pinhole-2-A09A3558

In this photo, Left is the Detachable Wide-angle (Diverging) Lens

In the Middle, Triangle-ish panel which got 3 selection of Pinholes can 

be moved to each position.      Right is a NikonAI  to  CanonEF adapter.

Multi-Pinhole-3-A09A3503

Photo left is my kitchen.

Or you may call my work shop.

—– you may realized, how

my work is casual.   😀

Still, it’s OK to produce

properly machined like quality ! 

Multi-Pinhole-4-001

And the photo here showed the effect of = with or without the

wide-angle lens.

Multi-Pinhole-5-001

And the photo here, right, the panel shows 4 holes — by moving

rear panel, the selected Pinhole will come to the position.

Multi-Pinhole-6-001

Photos from the window —

Left = Single Pinhole,   Middle = Triple Pinhole. 

Right = Concentric-DD Pinhole.

—– So, I have to go out to make worthwhile pictures !

* * *

Incidentally, a test shot of “that rose” with this DD Pinhole was:

1-Remake-DD etc2-001Considering it IS mere hole, without focus or any control, still

the image was somewhat comparable to a good German lens

—– isn’t this, amazing ?

—– Or, unlike the Leiz, the Zeiss might have kept their belief

on “Natural Optical Image” like this !

—– Mind you, the Pinhole is not a “Light-bending” Lens or a

Grass, therefore neither has aberration inherent to the Lens at all.

Still, the outer (larger)  hole of Double-Density Pinhole here is

acting as a “Dispersed” Light-pass, hence showing similar effect of 

the Spherical Aberration (= effect of light coming from not only the 

center but the outer area of the lens as well which is not necessary

converges the light to the same point = make the image softer.

Kyocera Junk Macro — in Practice

1-Kyocera-Macro7-0011-A09A3442I’m well aware, making lens etc is one thing and actually use it is the other. 

Still, whether any worthwhile photo was created by it or not, is totally

different matter. —– I know, in this world, some of the people is having

a pleasure of possessing something rather than use it = just for a show-off 

(of his, her wealth or So-called Good taste) —– and the manufacturer is

well aware of this phenomenon too. So that they are producing specifically

designed outrageously expensive model for this target, with “Art” or “Opus”

kind of the name.   A camera, recently introduced from Leiz, Leica SL is one of 

the extreme case, = the camera which can takes more or less the same kind of

picture but priced whopping  $7450 for body.   Even if non of the photographer  

would buy it, still 10 of the “Leica Collector” in the world ought to buy = because,  

it was made by Leiz and listed in their catalog.  (Collection has to be complete.)

Yashica Macro-1-A09A3208A Camera lens, I made out of junk

Kyocera-Yashica compact Zoom

Camera has been with me a

while  = waiting to encounter

good subject. ————————

Yashica Macro-2-001Then, I found a tiny tiny dot on a Fig = it was an egg of the Green Lacewing.

Not very fashionable subject still, it is good for a macro-photography.

So, that’s how the top photo was made. ( x4 Magnification. though, quality

of the lens in comparison to my previous work, was not very impressive

—– shows chromatic aberration etc, hence,  not very sharp.)

—– still, it was a proof that the lens was in operation. 

(= I’m not feeling happy for just possessing the lens.)   🙂

*

Kyocera Macro-355-001    PS :  In order to have a bit more sharpness and the evenness of the image,

I put a hole of Black tape to reduce the effective F-Aperture to half of the

diameter (equivalent of 2 F-stops down) = the image quality was dramatically

improved ! — You might be realized that how the optics behave in simple

manner and lost a faith to worship expensive lens.   😀

(In fact, we are paying for the Brand image, not necessary for the quality, 

otherwise who pay  £3000 to a plastic camera ?)

How to Save money ?

In the Net, there are hundreds of life’s advice kind of site.

How to maintain good relation or before it, how to start, or where to find the mate.

The advice from a very experienced mature person to a very young person saying

how and why she or he was attracted to what sort of the person etc etc.

(In most of the case, the advice was not more than a good common sense.)  

         An advice which took my eyes was how to save the money, by not to reduce

the spending but simply just stop to buy it altogether.  I guess, the woman who was

advising must be saying it from her hundreds of failed experiences.  In certain sense,

it is a simple commonsense though, when the matter involving was a person’s desire 

or the habit, it’s easy to see, common sense may not necessary works. 

When someone drinks, the person may not counting the number of glasses — but

just want only one more glass.   So, to attempt to save a money by reducing the

consumption could be a hardest to achieve. 

I’m not knowledgeable of this kind though =is there such deal viable to negotiate

with a prostitute if a half of insertion could save her charge half ?   May be not.   🙂

Saving the money is not a matter of economics or a business management but 

it is the very trouble of the MIND. 

That advice in the Net, “Stop to buy it completely” is in fact parallel to the Zen.

Zen works on the base of  All or Nothing because of it is either in Mindful otherwise

it is not exists. — In our mind, if the mind of Drink was there, the Drink is there.

= you can’t have “Half mind of Drink” same as a half of the Drug or a half of the Sex. 

As long as a Receptacle of the Drink, Drug, Sex is in the Mind, we can’t stop to take it. 

But once such mind was removed = ie;  the receptacle was not there, we couldn’t

recognize “What the Drink is”  “What the Drug is”  or an image of a woman

couldn’t be connected to the Sex.

[]

The secret of this “Mind Engineering” is, how to train our Mind = make the

signal jump over the Emotional region of the brain in the Limbic System

which is dealing with Desire, Greed and Want.   To train the Mind, Zen (in fact,

all the Buddhist sects) has the long, repeating practice which ware-out the

Emotion.  ( The brain started to ignore the repeating signals and start to

process the signal without involving the Emotion. = such as a sign-board on the

street, became almost invisible, while you are passing on front of it everyday)

Once the person mastered this Mind, the Drink, Drug or Sex become non-existent. 

And as the Mind will just pass the signal without triggering any reaction =

“Drink ?  — What’s drink ?”   “Woman ? — Yes, I can see it’s a woman.  So, what ?”

Give-up altogether or stop to buy, is much easier than “Reducing its consumption”

because there is no conflict of “Want” and “Shouldn’t” in the Mind.

(And the most funny things was, once the person mastered this Mind-set, he or she

could pick-up a glass without a hindrance but never take more than a sip, because of

there is no desire or attachment NEITHER the Mind of Prohibition or Restriction.)

And this is the best way to save the money and to have a trouble free life.   🙂

Shake shake (2)

Shake B-11-A09A3342

There was a very similar photo of this, taken by a completely different technique

in this blog. = It is interesting to see an image of the 3D movement (depth) in

that photo was still captured as a 2D spread (shift) of the element.

Shake B-12-A09A3348

What ever the technique or accident created its image, the matter is how the image

boggle the mind.    And what ever the origin of the image, some of them stuck and

remained in the depth of the mind very very long time.

[]

Shake shake (1)

Shake-1-A09A3345

There is nothing special of those photos, no trick, they are just

blared photos because of the camera shake.

Camera shake because of the slow shutter speed = 1/2, 1/4 sec’ kind. — And

to have such slow speed, lowest ISO setting and a dark ND filter was used. 

Shake A-01-A09A3327

Shake A-02-A09A3344

Shake A-04-A09A3331

So, it’s easy to have un-sharp pictures —– just shake the camera.

(Of course, if you like.)   🙂

Junk to Macro Lens = Recycle of Kyocera Zoom Lens

Yashica Macro-1-A09A3208

You might be misunderstanding that I’m playing with cameras for the

sake of blogging. Far from it, behind the scene I’m disassembling

3 times more lenses or cameras.  I only showing them if I found a fun.

In most of the case, I’m doing it just looking for a spare parts or

particular component such as when I needed to get a mirror for an

ultra-low-angle photo-adapter.     —– I was disassembling a Yashica

compact Zoom camera, looking for a Motor and a Gear mechanism.

— Some old film cameras had auto-wind and rewind mechanism which

I could utilize in the other mechanical design.  So, from Yashica, I got

two motors with each gear mechanism, and not only that, I found an

extending Zoom lens barrel seems to be very useful. 

I had used a same kind of barrel to make a focusing helicoid.

Yashica Macro-2-001

This Kyocera-Yashica 38~115 mm zoom lens seem to have a quite 

fancy design.  Front group convex lens has a Canon like Arc-formed

motor for focusing and having aspherical lens, and rear group is pure

diverging concave lens.   And I found the front group lens works well

as a macro lens (used in reverse) = So, mount the lens into the

extending lens barrel = Here I have a x1~x3 (about) macro lens.

Yashica Macro-3-001

Yashica Macro-4-001

This front group lens had a Shutter-aperture-combined blade which

I removed therefore there is no F-Aperture = always fully open !

—– still, this sample photos showed rather good quality and giving

beautiful out of focus bokeh.

Kyocera Macro-354-001But with further test, lens showed strong curvature of the image =

image is not flat = good for 3D subject but not good for a flat object.

(When lens was designed, the aberrations, inherent to any single lens

were corrected by the combination of the other lens.  Yet, in this case, 

such strong curvature of the image needed to be corrected by the 

strong diverging lens of the rear group.  But, as only front group lens 

was used here, the uncorrected aberration became too apparent.

—– Photo above Left showed x3 image.  Its coloring was caused by the

Chromatic aberration.  Photo Middle (x1 size), the best focus was made

to peripheral.  And the Right, best focus was made to center.   The focus

to the center is 4mm different ! = If the subject was 4mm deep shallow

dish, this lens will make a good focus from center to the corner.)

I need to find a good subject. = Ideally, Halloween Costumed insect.   🙂

Not heal by Buddhism ? ! 仏道からの癒し---それともコーヒー?

彼岸寺といふ仏教サイトに面白い事が書かれていました。浄土宗の日下と言う僧侶が書いたもの

だそうですが,彼は何故か仏道に癒しが感じられない ---むしろ一杯のコーヒーや家族に

癒されるとのこと。浄土宗では教えないのかも知れませんが元々の

釈尊の教えは「無私」ですからそもそもコーヒーを愛でる己れ,家族に愛着した己れどころか

対象としての仏教なるもの自体が存在しない。

---という現象を学ぶ為に仏教では延々と続く勤行を繰返し,それを無意識,無感情でする

(無私無心)訓練をする。=無私無心でちゃんと生活が成り立つ =では誰が生きているのか?

= それが法 / ダルマであるのです。

己れにしがみつきながら,どこか彼方から 癒しが得られるのでは,と期待するのは

お門違いでは???

* * * *

In one of the Buddhist’s site “Higan-dera” in Japan, a monk called Kenyu Kusaka

wrote a short essay saying that he noticed that he is not feeling the heal from

Buddhism, but from coffee !  He was a Pure-land sect monk, so that expecting him

to have the understanding of what Buddhism IS, might be too much to ask.

[]

The core of the teachings of

Lord Buddha was, First, there IS no such thing like SELF (Atman) exists. 

And to learn this truth, the followers practiced long repeated practice

until they could do it automatically (= without thinking) and without emotion

(= no-emotion / not having a feeling of SELF = hence realize No Existent of the Self )   

Without knowing this teachings, the monk may still thinking that there IS the

subject called Buddhism and a person who is learning it.

No such things there or anywhere = if only a person doing the practice and the life

without having the SELF, what prevailed there IS the Dharma.

(= if the person IS NOT there, who is living there = That IS very Dharma)

[]

But a monk like Kusaka, clinging his SELF and attached to his family AND a cup of

COFFEE, Buddhism is too remote, yet wanting to feel a healing ?  What he is asking ?

There is a big irony, —– as long as the person asking, never given, as long as

the person looking for, never find. = The EGO of want push the goal away.

Focus-Shift Flower image

F Shift-1-DSC_6287

Somebody in the USA contacted me to use one of my old photo which was

taken by a technique of Focus Shift, hence the image has big off-focus

bokeh superimposed on it.  In fact I’ve published such photo many times

like this or this. (though, the gear used or the lens may not be the same)

And even there was such drastic approach.   🙂     But this time, focus ring

was moved manually, and in order to have a slower shutter speed, shooting

took place in the evening, under rather dim light.

F Shift-2-DSC_6270

And to make off-focus, shift to near or far, or the setting of F-aperture etc,

above all, how far the subject, will make the picture looks quite different.

(still, there is no fixed manner = it’s just case by case.   🙂  )

F Shift-3-DSC_6276

F Shift-4-DSC_6283

Funny things of Focus Shift is, first moment, it was focused to the main

subject, then move the focus, generally till completely out of focus though,

F Shift-5-DSC_6284

why not focused here and there.  = Two subjects will have each clear focus

(and bit of bokeh)  🙂

F Shift-6-DSC_6277

F Shift-7-DSC_6272

Camera used here was the Nikon D810 — having had 37Mp image-censor,

there are ample of space to crop the image.

A radio DJ mentioned Xmas —– Oh no, soon it will be the November

—– still, flower patch has few flowers left.    Thanks Goodness.

Tofu-Tofu

Tofu-Tofu-1-A09A3074

Since last time when I’ve talked about how I was annoyed by the Chinese Tofu,

I didn’t have any Tofu cooking —– it has been completely disappeared from

my mind. (Same as like when I stopped to touch woman or smoking, or even

just stopped to go particular club or shop.)   A funny thing was, that Tofu has

been in my fridge, thus, seeing it everyday all through those period.   Though,

I didn’t even think about to chuck it away.  It was not exists in the world.   🙂

Tofu-Tofu-2-31-001

So, I don’t know why I got an idea to buy it again and make a particular

cooking. (That cooking will appear in this blog soon.)  

And for that, I did a special shopping at a Japanese food shop.  (Then

I noticed that the Japanese Tofu (though, they were made in USA) having

pretty long shelf life = enlarge the photo above to see each “sell by date” )

(Those Tofu I bought, were either made by Morinaga or House = both are

pretty big company thus, least likely do any cheating while taking a risk.)

—– And, I show you “That Tofu” after 7 months. (Photo above Right) =

looks quite edible if not poisonous.   Japanese Tofu sold in a Japanese

food shop is twice more expensive, therefore I never bought them before

—– but there is no alternative left to me. 

( And I’m not such keen to make a Tofu from the Soybean.  😀 )

And I didn’t know that the Japanese Tofu is having up-to 6 (six) different

grade of firmness ! = how civilized, how sophisticated !

= almost obsessive Japanese over quality !    😀

* * * * * * *

Incidentally, a feedback for eating “Japanese Tofu” first time was, — I’m

not necessary like Boxed Morinaga one. Their texture is artificially smooth =

almost plastically. —– I rather like to have more natural-food like uneven

texture = like the one, made by the House Food.

Still, this is the Zen

Bowl-A1-A09A2786

Bowl-A2-A09A2784Seeing a scratch on the surface of the washing-up

bowl in my kitchen which I’ve been using since I have  

started to live in this flat, I realised that the dirt or  

stubborn coating on the surface of this plastic bowl 

could be removed by just scouring hard.  —– I was 

thinking to remove such limescale mixed stubborn

dirt needs to use a strong chemical such as limescale

remover kind of acid.

—– There was the choices.  

Throw away old bowl and buy new one.

Anyhow, it was only a couple of pound cheap item though, strangely

I couldn’t find the same shaped one in any shop.  

Other choice was do nothing. = as it has been used 15 years, why not

another 15 years. — utterly lazy and sound hopeless though, to make

nothing happen is a kind of peaceful choice and cost nothing too.

One of the famous Japanese monk, Ryokan said to have one pail and

he used it for everything, to wash his foot to serve a rice.   So, use one

bowl only for washing-up many many years wouldn’t make any crime.

[]

If I can clean it by just scouring, why not to try. = When a spoon edge

made a scratch, a scouring pad made by metal mesh should work well.

—- So, I did. (to the half extent) It IS a simple work = just scouring,

scouring and scouring.  The more scour,  bowl become the cleaner.

While scouring, I just scouring (=Mindfulness) = no thinking.(Mind is

in the Mushin / Void state.)  

This is the Zen. —– soon or later, the bowl will get perfectly clean state. 

Exactly the same process, the Japanese Sword was perfected. (Strangely,

we aim always the better — who asked ? or because of our nature/Dharma)

You may laugh though, the bowl which became clean is the equivalent 

of the enlightened soul.

—– Yet another teachings may say,  neither a bowl nor soul kind of

things was there in the first place, who get enlightened ?

Good question.
