Re: [pinhole-discussion] RESOLUTION AND PINHOLE

[Mark Interrante]

Hi,

Has anyone calculated the effective resolution of the zeroimage multiformat
camera?  I'd be also interested if anyone knew the resolution of the zeroimage
with zoneplate instead of pinhole.

Thanks,
Mark

Philippe,

from the normal distance (2 * diagonale from 24cm * 30 cm) looks your
picture sharp. Try a test.

 Thank you Guillermo and Gregg,

 I still have to read the interesting paper.
 So if my optimal pinhole diameter for a 100 mm FL is 0.36 mm, this means
 that my 24x30 cm film will record an image where every point will have
a
 blur of 0.36 mm. So it is impossible to have sharp detail with pinhole
 photography ? Isn' it ?

 (Well, yes, it's a pinhole if you tried to fit your head thru it).
 
 Thank you.

That's about the right size for a 2.5 kilometer focal length...
