A silly question.....but then I am not sure of the answer. Does a camera 'see' UW like our eyes? That is, nearer and larger? It is subjected to the same laws of light refraction as our eyes. If then my camera manual says 'minimum focusing distance is 12"' (air), is this 9" (or is it 8", can never remember which) underwater? Or is it the real physical 12" still?
