Double-Density Pinhole Photography

Ideally, soft-focus image should have solid focused core and the soft flair around it.

The more the photographer is decent grown-up person, even soft image is rather subtle.  Though, I’m not very well grown up decent kind = tend to take it to the extreme   😀  (Hence, if I cook for myself, the taste is pretty strong = if it got to be spicy hot = it would be extremely HOT = Otherwise, what is the point to cook hot food  😀 )

Therefore, my soft-focused image goes to even more extreme = and in this  experiment, I gave a larger pinhole halo to small pinhole image = Concentric Double pinhole photo image  🙂   My approach to the Life is ” Why not ?”  😀

How you can put small hole inside of another hole  ? ? ?  = 😀

This is a Philosophical Problem = Hole is where VOID is = unlike gap, hole was represented by its circular edge, and this edge define the area of the Void = its inside is already Void, hence, there is nothing to form yet another hole  😀 

In photographic term, Pinhole can act like a lens, provided when the correct exposure was given though, when two hole exists in the same place, how to give long enough exposure (shatter time) for smaller hole while giving shorter time for larger hole ?  = 😀

—– My solution was, to cover larger hole with ND filter to reduce the incoming light.

(There is a gray filter called Neutral Density Filter to reduce the light, though together with Kodak CC (Color Compensating) filter they became hard to obtain item now.) 

—– Instead to use ND filter, I found an Aluminum coted plastic film of tea packaging. —– Not good enough for normal photography yet, enough for fuzzy pinhole photography  😀

[]To measure the Density, I placed this metallic film on front of the lens = the exposure reading was dropped from 1/1000th to 1/15 = 6 stops drop on shutter speed. 

Hence, the size of pinholes should have also 6 stops difference in F-aperture logarithmic scale.

(such as 2mm, 1.4mm, 1mm, 0.7mm, 0.5mm, 0.35mm. 0.25mm = larger pinhole, 2 mm and small one should be 0.25 mm)  —> The metallic film was stacked behind of 2 mm pinhole and a 0.25 mm hole was pierced in the center.  —– (From the result, I think, the lager hole should be 1.5 mm and smaller hole 0.18 mm = images would be a bit more sharper  😀 )

Still, the experiment which costed virtually nothing = results are not too bad  😀


PS :  Few people who has failed to do this kind of pinhole photo asked me why —– I’m using equivalent lens (this time 100mm lens) for set-up and framing, then the View-finder was covered up with black-tape.  Stray light from View-finder makes wrong reading of exposure.

Most importantly, I’m using extremely capable Canon 5D (Mk 2 and Mk3).  

Pinhole photography may not be done with another camera. 

For instance, a pinhole shot done in 5D Mk3, with ISO 3200 and AV setting, 6 seconds —– the same pinhole mounted on Nikon D810 with the same ISO 3200 setting and 6 seconds couldn’t make picture, as it looks more than 3 stops under exposure.   Even with 30 sec’, 60 sec’, 120 sec’, further with ISO setting Hi2 (equiv’  25600) didn’t make ANY difference. 

Nikon couldn’t work with non-CPU incompatible lenses.

—– I wonder if anybody has ever done Astro-photography with Nikon D810, I would like to know how it was done ?


PPS :  I found the way to to take Pinhole Photo by Nikon D810.

(1)  Go to the Menu / Non-CPU Lens / and set Max F-Aperture to F22.

(2)  Push Meter Coupling Lever (for Aperture Ring) anti-clock-wise, till F-aperture indicator on the Control Panel shows F45.

(3)  With ISO setting, 3200 or so and [A] (Aperture priority) = camera would give more or less correct exposure.

(*)  To adjust the exposure, even if you use the Exposure Time given by [A], say 2 second for Manual setting and select 1 second or 4 second —— exposure couldn’t be correct unless you push Meter Coupling Lever to F45 position.  (Because, the brightness of the image was not determined by the size of pinhole and the shutter-time, but by the gain of signal amplification in the image process )

 —- In fact, you can control Exposure Level by this Lever (by pushing it to F32 or F64 etc) = it is very awkward —-> Solution would be, tie a string to the Lever and fix it to the position of F45, and the Exposure adjustment should be made by changing ISO setting to another value.

    Ethereal images, yoshizen. I like your”extremes!” 🙂

      Thank you Karen.
      You are the master of showing [Beyond of what we can see].
      This is my approach to the photography [to hide the reality] and suggest [There might be more].
      (Technical substitute 😀 )
      Now I’m pushing it further with smaller hole which should give a bit more sharper image 🙂

    A hole inside another hole, thats the question? 😉 Well, the technical things is not my thing, but I certainly like the topic anyway. Very interesting an nice, soft photos, Yoshizen.

      Thank you Bente.
      Now I made smaller hole version and looking for a flower 🙂 = I’ll post yet another “soft photos” soon.

    WOW! These are wonderful images!! I love the notion of pushing to extremes. I’m completely inspired by these beautiful, evocative photographs. They have an almost haunting quality to them.

      Thank you very much. I’m grad to find “well focused fanatic” also loves soft focus image 😉
      We might be seeing something beyond of what we are seeing = in other words, if not all the details there, we may use our inner eyes to see = that is what we feel “haunting”.
      I’ll test if XL5 or XL7 can do pinhole photo or another way to explore soft focus for your camera.

    Hey Yoshi! Very nice photos you have here, its a very interesting style I like it! This is John. Hope you’re well.

      Hi John. Welcome to my blog.
      To find the DD-Pinhole photo, you must be quite knowledgeable for photography.
      I’ve seen your site = nice 3D work ! I like it.
      How do you think the Zappa photo ?

    Hello Yoshi,
    How good is your memory?

    • yoshizen said, on November 22, 2015 at 10:13

      I know quite few Duncan — still, the one interested in DD Pinhole must be the one
      who used be in the Studio-B and moved to a studio in Old Street then Derbyshire.
      Are you still in that small town ? And doing photography ?

      It’s very strange, on this November, after 30 years raps, two of my old friends contacted me.
      Question was, how they found my Blog or mail address ?

  17. Duncan said, on November 22, 2015 at 12:30

    That’s the one. The only Duncan of any importance 😉
    In a different small town now but still in photography.
    Contact can be via the website if you like – wherrett.com
