Came up with an idea. Toyed with the idea of trying some pinhole photography but something always seems to get in the way. Came up with an idea to turn a regular film/digital camera into a pinhole using a body cap. Should work on any 35mm digital ect that would accept that kind of cap, and an extra cap in the bag weighs next to nothing and no bulk or extra stuff to lug around.
Would you be shocked to learn they're commercially available? I have one for my Nikon bodies. I've done a tiny bit with it on digital; I should try it on the D700, which should be a bit better than the DX cameras; a bit.
Now I suspect the smaller the hole the better as far as sharpness, but is there a group of sizes that I should try? How much of a difference in hole size should I allow. Granted a body cap isn't going to alter the GDP, but its not like getting another piece of cardboard either. Id be interested to hear thoughts and ideas of those with pinhole experience.
For sharpness, there's an optimal hole size (depends on distance from sensor), and either bigger or smaller loses you resolution. For 35mm-size cameras, going for sharpness is a mugs game, though; you don't get sharp pinhole photography from that small a neg.
