It is better to start with 16 bits but if your doing a lot of tonal manipulation
on an image it is good to switch an 8 bit file to 16 bits for the adjustments,
even if you switch it back to 8 bits when finished. If your only doing one
adjustment then it will buy nothing, but for a series of adjustments it's a good
thing to do.
16 bit mode essentially keeps track of all the fractions generated by the math
going on, when you switch to 8 bits it rounds off and the later the better.
