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.

    Cool work, Yoshi. I love the red flowers!

      Thank you Karen. That flower is the fixture in that corner and the test chart of all the experiments.
      If that flower looks reasonably sharp still shows smooth softness, the lens was good. 🙂
