Hi
I want to print a Ronchi screen and I need some suggest.
How many lines should I print for a 24x36 camera?=20
How thick the lines should be?
Is better printing a lot of thin (0.03mm) lines or few thick (0.5mm) =
lines ?

I will print the screen on a transparent media and then I will put it =
the focal plane
of an Olympus OM-10, I want to set focus with OM-10 and next change the =
OM-10 with my OM-1
and take picture. Will it works? Same brand camera should have same =
focus point, isn't it?

thank for helping
