comment Are picture files “random enough” to be usable as a one-time pad?
methinks that taking random pictures should be OK. No way as a 1M*3/2*8 random bits, but (wild guess) 256K random bits, provided the lighting conditions are in natural range.

You need full control of the acquisition process in order to avoid fake images (as demonstrated by John Deters). You usually have better sources of random bits than camera.

... although if the process involves controlled capture with an attached camera, the #000000 problem can be excluded.
