I don't know if this is the good direction (use a pinhole for exposure Lippmann) but there is a very interesting software to design your pinhole camera.

Seems that for a 4x5 plate, the best focal length is 6,4 inches and match the normal focal length (of eyes ???). But I'm guessing that exposure time with a pinhole will be too long.

Interesting,



I'm maufacturing a solid photopolymer plate sensitive to red but it will tune down to yellow-green upon development :(



This is almost solid coated on glass and PET Al mirror laminated so I guess would work with long exposures, so I could spect a Lippmann image monochrome, but in theory more intense than films, another interesting idea is make a Lippmann on a wide band DCG.
