Veijo, these are simply AMAZING. I don't think I ever saw better pinhole photos anywhere. |
Thanks 
Of course, some purist might not like the post-processing I've done, but I'm not a purist and I also want to show that pinhole photos can have a lot of photographic potential - just like the old lenses do have. If I'd show these pinhole photos at a "normal" web resolution, say 480 pixels wide, most people wouldn't even suspect that they are pinhole photos and would probably accept them as rather high quality ultra wide angle lens shots - this is the danger of the small demo photos on the web.
Just to drive home the message, here are two of the 1200 pixel wide images down-sampled to 480 pixels:
There is nothing tell-tale about these photos as the vignetting and the geometric distortion are unavoidable and would be there with any lens having the same FOV - a lens would probably have even more vignetting, much more. The shiny surfaces in the church photo are very deceiving as they create a false impression of sharpness - subconsciously you don't even expect to find very much detail in them, which gives them an aura of fidelity. This is a very useful trick of the trade

Both these shots are exceptional, but the second one goes directly into my absolute favorite photos that I ever saw. Total depth of field and zero architectural distortion. My dream "lens".
Did you use your "native" pinhole camera for these photos, or did you adapt a normal camera with a pinhole aperture?

Yes, a dream lens - the only problem is that for maximum image quality the FOV must be as wide as possible, which means that you ought to look at the photos from rather near in order to have a somewhat natural perspective.

These photos I took with the Zero 2000. The IQ of the modified Zeiss Ikon Nettar is much lower due to the longer "focal" length which requires a larger pinhole and thus lowers the obtainable resolution. Otherwise the camera has very little effect on the IQ as long as the pinhole is properly dimensioned, clean and punched into a thin enough plate not to cause undue vignetting.

This one has been setup from an old Agfa Clack:

I thought it could be of interest... At least the article is.
Best regards,

My daugther has brought me one from the US. It's a nice cardboard camera that I've to build up by myself from precut cardboard pieces.
The pinhole is punched in a tiny metal disc.
Best regards,
Jes.

Pinholery is fun, and I'm always impressed by the zero camera's results. They use a very short 'focal' length, and a smaller than usual pinhole to get the sharp images, I've read.
Lenox Laser sells pinholes - I've bought a SLR body cap from them, and then a pinhole for my Certo Super Sport Dolly conversion. I find Lenox's calculator and recommendation gives a slightly too large pinhole size, I wish I'd ordered a smaller one for the Certo.
Here's an image of the Brooklyn Bridge with the pinhole behind the shutter - thus the vignetting. On my second roll I put the pinhole up front, which eliminated the vignette. I think with a smaller hole there would be more detail available.
And here's the camera itself:
