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.

Larry, Thanks for making this. I'm sure you have already put a lot of work
into it... but i get nothing but a blank bitmap. No rings at all.

Subject: [pinhole-discussion] Zone Plate Image Generator
Folks,
I have created a zone plate image generator so that I could make my
own zone plates. The program downloads a .BMP so it's PC centric, I think. The
idea was to use the program to generate a zone plate image and then take it to
the bureau to have it put to film. They charge about $15.00 for this. I haven't
tried it out yet so I don't know how well it works. I'll be visiting them on
Friday and I'll drop it off then.
The calculator/generator is at http://www.MrPinhole.com/zp.html
