Re: [pinhole-discussion] Zone Plate Image Generator
Benno, I guess it needs more instructions. I'll put some together and put them on the page. Basically, the width and the height are MM and tell what size film you're going to. Then the focal length is the distance between the zone plate and the film. The number of rings is up to the user. The resolution, DPMM, should be around 100 to get a good image. That translates to roughly 2500 DPI. Are these good enough instructions? Anyone want to add or comment on them?

Re: [pinhole-discussion] Zone Plate Image Generator
john, Yes, I did put a few hours into this, but it was fun. Thanks for appreciating that. What were the settings you typed in? I'd like to repeat them to see what I get. Also, sometimes you really have to look for the zone plate in the middle of the image.

[pinhole-discussion] Recommended Exposures onto Paper
Hi, I am new to the digest and to pinholing. I have successfully made a nice little super wide PinHolga and am on to a superwide Leonardo now. I would like to throw some photographic paper into the Leonardo to do some test exposures and was wondering if anyone has woked out an ASA equivalent for photographic papers. I will be using Ilford FB paper. Any help is always greatly appreciated. Also, did anyone notice the fantastic pinhole photos in the September (I think) issue of Aperture mag? This is what brought me to pinholing. take care and enjoy, bob peak -- Bob Peak, Jennifer Carpenter-Peak, Dakota Bali (the Crested Chocolate Husky) 9 Colonial Village, Berkeley Springs, WV 25411 304-258-7647 **UPDATE: New Portfolio Site** http://www.portfolios.com/peak See Our Article in Bicycle West Virginia @ http://www.bicyclewv.com/articles/around.cfm

Levi, Your energy is contagious. Your ideas are wonderful and simplify the concept of the swap. I like it! I like you! Where are you? What country, what state? leezy
Re: [pinhole-discussion] Re: PRINT SWAP: Self-portrait as the topic?
I love the idea of a print swap! Count me in! There has been some debate on having a theme of self portraiture. I think that this is a fantastic idea. For those of you who prefer to leave your artistic opportunities open, opting to have no theme, consider this. A self portrait doesn't have to have the photographer in it. Anything, so long as it reflects the photographer (the self) in some way, is a self portrait. For a self portrait assignment in school I once photographed a grisly dead opposum. It was a lovely reflection of my depressed side, and I later sold it to some guy in Florida who collects images of roadkill (he said that since his sister was killed in a hit and run accident he has developed an interest in the subject... I don't beleive him... but it makes a good story) Anyway, I think that self portraiture is a great idea. It forces us to look a subject that we often shy away from. Ourselves. There is somthing wonderful about looking at an image of yourself and saying who is this person? That is my take anyway... Levi
