Can one see thru the prism/viewfinder on an SLR with a pinhole drilled body cap? principally: yes. but you need a considerable amount of light. Does one need to cover the eyepiece on an SLR conversion to prevent stray light entering thru the eyepiece? Depends on the quality of the camera

Hello, hi there ... I am using a body cap with a larger hole cut out, about 5mm or 6mm and then I am applying soda can aluminum to it. Thin enough? sounds ok. I will be using a 30 gauge syringe needle. Which is smaller than a pin. I called BD (manufacturers) and found the external

Hello! But then i thought 2:1 or higher magnification with a lens camera would have a bellow extension of 600mm and more. So would a 300mm pinhole 8x10 camera for macro work be kind of a wide angle? As a pinhole doesn't have an inherent focal length, you can shoot a 2:1 macro with any

Why do you suppose that is? Pam Michael Keller wrote: I've used a zone plate on a Nikon D1. Not real thrilled with my results, but I think it's just me. With digital, long exposures can lead to increased noise in the shadows. The CCD chips tend to give a signal not only when

Yes, the digital cameras with interchangeable lenses are quite expensive (cheapest is a 1.4 mp Olympus at $1500 list); but ccd video cameras aren't exactly cheap either. well, I had in mind the CCD camera modules that are sold as door spy etc .. you need to look for a (cheap) power supply and

Has anyone tried taking pinhole photos using a digital camera? Hi Pam, I think it would be more promising to use a CCD video cam with an exchangeable lens. Digital cameras with removable lens systems might be rather expensive (there are a couple of new professinal devices based on 35mm
