Well, this is my first time attempting something like this. I suspect they
will all look the same pretty quickly and get boring. I can't see this one

When you focus a lens using a ground glass, you are just making coincide
the -ideally- flat image the lens is projecting with the surface of the
ground glass, if you remove the ground glass, your eyes can't see the i

Although I do not recommend focusing of the zoneplate every time you make an
exposure, I do recommend you focus it ONCE so you find out (if you wish) the
actual focal length of it. To do it, aim your camera to a light source

I think technically they should be refocused (anyone, please correct me if

simply setting it to it's designed focal length and shootingIMHO little

I'm hacking up an old TLR right now to put another shutter on it for zone
plate work, and I'm wondering, how critical is the focal length for
focusing. If I'm putting a 90mm zone plate on, but due to mechanical
impediments it has to mount at 95 mm, how much of a difference will this
make in the im
