Evolution of PINHOLE System


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.


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.


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 ! 


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

wide-angle lens.


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

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


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.


3D View ?

3D Test-001

On the second previous post, (to those Tri-color Photos) Photographer Karen

(drawandshoot) put a comment wondering what would happen if those picture 

 was seen under a 3D glasses.

—– My understanding of 3D image was, that if our each eyes receives the image

of slightly different viewing angle, our brain Re-configure them into one 3D image.

(but 2 different images has to be the images seen from the position, horizontally 

shifted about 2″ ~ 3″ distance = in short,  like the images seen from our eyes  😀 )  


So, I tested it —– to see what happened ?    

The crucial point of my Tri-color Pinhole images was, each Pinholes were separated

 less than 2 mm. = It’s mean, the difference of each images in Sky, Pink, Orange 

colors were very small, almost identical. —> therefore they didn’t make 3D.  

Funny thing was, the brain (my brain) seemed to have a big difficulty to comprehend 

the images which got Sky and Pink in the same time.  —> So that, a moment to moment

the dominant vision Left or Right changes = suddenly the images changes Sky to Pink

or visa versa. 

(If you are good in 3D view in aerial photo kind, try the top photo here, = to see

Pink photo by the left eye and Sky photo by the right eye.  Actually, as each eyes seeing

different photo, this color change wouldn’t happen but more likely the brain sees

mixed colored image.    But if you try to see, such as this one with 3D specs (if you have

one, or use color gel) you may seen the phenomenon = dominance of Right or Left brain

changes.  =  This must be our brain’s defensive response.  Like our left eye is connected to

the right brain = a kind of evasive action to limit the damage when our head got injured.  

There couldn’t be a possibility  of one object having two colors in the same time = it’s  

mean, eye could gotten wrong, otherwise visual cortex got wrong —> hence the brain is 

testing the system by rapidly switching and changing the channel.  Interesting isn’t it ?



Morning Sky


Well, most of the morning sky in the Autumn, in London are dull gray.

Still, time to time we can see the sky like this.  This was the sky on 

the 17 Oct’ 2014 / 6: 46 (long before actual sunrise over the roof)

The lens used was Canon EF 40 mm F2.8 on 5D Mk-III.


—————————– 7:17 ——————————————- 7:19 —————————————— 7:24

The photo in the middle was by Tri-color Pinhole.

(Otherwise it looked like next — 7:24 photo)


————- Then, I saw the sun over the roof.   8: 08 ————————————- 9:34

In fact, the last one = 9:34 , the sky was just bright, colorless sky.  

I’ve added the color by  Tri-color Pinhole. (Sky, Pink, Orange)


So, this was the cloudy sky this morning,  8:10  colored by the Tri-color Pinhole.

It’s somewhat convincing isn’t it ? —– it may looks like a Turner’s oil painting.  

I like this as a good joke.   🙂 


Sky-Pink-Orange Tri-Pinhole Pictures (3) = Pretty Images !


Pinhole Photography is so easy and even Tri-color Pinhole is not difficult to make =

just put small (3×3 mm) color filter sticked on the back of each hole.  —– Only a

tricky part is, as the viewfinder was masked with black tape, shooting has to be done 

blind, it’s mean the composition and the angle of photos are all in guess work.











And those colorful images appeared after the image was tinkered, the shooting was

done more or less on the speculation —– still, after hundreds of the experiences,

I know what to look for.   When the results got a sort of sweetness, it got a maturity.


Sky-Pink-Orange Tri-Pinhole Pictures (2)


If you are tired to see this kind of looks all same images, I should say sorry

but still, I would put you into misery few more times. 


In here those Tri-color pictures, the trouble of Orange color in the previous post

has been sorted out and the position of Blue and Orange were swapped. 


 As its character, Tri-color Pinhole images are inherently gorgeous.

It makes one flower suddenly trebled and put a color to each one.  

—– How marbelous. 😀







As I’ve explained in the previous post, those exaggerated color was not made by

any fancy program but by just darken and brighten several times that all.

(with an adjustment of  Wammer — Cooler color a bit)

For me it’s a fun.

Pale Blue -Pale Red and Orange Tri-Pinhole Pictures

DD-Pale BR,O-01-A09A4421

Well, this was a further attempt to create colorful pictures out of otherwise

boring whitish flowers.  The effect of Yellow filter was not strong enough on

the last post, so that, on here I’ve put Orange instead. 

DD-Pale BR,O-02-A09A4437

So, white cosmos was tinted with Sky, Pink and Orange ( not so apparent).

DD-Pale BR,O-03-A09A4423

Then it was a riot of color Sir !

DD-Pale BR,O-04-A09A4415

DD-Pale BR,O-05-A09A4447

DD-Pale BR,O-06-A09A4448

DD-Pale BR,O-07-A09A4453

The flower’s own color such as yellow or pink was retained more or less as it was.

DD-Pale BR,O-08-A09A4416

With slight adjustment of White balance, the effect of blue became predominant.

DD-Pale BR,O-09-A09A4443

And to have some exercise.

DD-Pale BR,O-10-A09A4456

DD-Pale BR,O-11-A09A4458

DD-Pale BR,O-12-A09A4465

I think, an attempt to have colors out of white was worked — at least.


PS : Somebody asked me “What Digital Filter / Effect was used to create

those overwhelming reddish color ? ” —– I answered him “In my policy, I don’t

use PS kind of digital manipulation.   I use Picasa to file, which came free with Google.  

So that the photo above were just tinkered (brighten, darken, clopped) by Picasa, still

brighten and darken the same picture repeatedly, the contrast of the picture increases,

in other words, the color would be strongly saturated.   Since the picture having red

element because of the pink and orange filter, they came out quite strongly.  

Reason why the reddish color tend to be in the left hand side was, that’s because

on the three pinhole positions, pink was upper side, orange was left

and blue was right bottom.   (I should make them rotatable.  🙂 )


Pale Blue-Pale Red and Yellow Tri-color Pinhole Pictures

DD-Pale BYR-01-A09A4347

The previous post [Blue-Orange-Red Tri-color ] was obviously too reddish.

Yes, Red + Orange was too strong indeed.

DD-Pale BYR-02-A09A4348

So, I tried Pale Blue (Sky), Pale Red (Pink) and Yellow next.

DD-Pale BYR-03-A09A4388

Though, the effect of Yellow was rather weak —

It gave only a bit warmer color-temperature.

Then I realized that the pinhole for Yellow was not clean round hole. (too late)

DD-Pale BYR-04-A09A4387

DD-Pale BYR-05-A09A4353

DD-Pale BYR-06-A09A4354

DD-Pale BYR-07-A09A4356

DD-Pale BYR-08-A09A4395

DD-Pale BYR-09-A09A4376

DD-Pale BYR-10-A09A4364-002

DD-Pale BYR-11-A09A4363-001

Still, end results weren’t too bad.

(But I need yet another try.)
