I have been working on a project for quite some time that involves the use of pinhole sieve, and to the left is an example image. This work is recent to the point that I have yet to give it a title. The results have made my other pinhole work appear to be sharp by comparison. The interesting thing about exposure through a pinhole sieve is that specular elements sometimes appear in places where they do not belong. This has been gaining interest with me.
When I try to explain a pinhole sieve, I seldom think that I have gotten the point across, so to the right is an example of one. Of course, a real pinhole sieve will be considerably smaller, but the idea is that the pinhole is surrounded by progressively smaller pinholes. This results in an increase of exposure speed and a lessening of the definition of the subject matter.
I believe that the results are similar to zone plate photography, and will be running some tests at a later time to visually see the difference.
Meanderings, at best 
This example reminds me of zone plate work. I’ll be interested to see more!

Thank you for the link. The photos there are so beautiful and dreamlike! My favorites are Turning Around and #s 3, 4, and 8.
