Digital BW, The Print

My 2 cents,

I "sometimes" increase the bit-depth.

But, I'm a superstitious fool for the most part.

When I think I want more data, I up-sample one way or another.

Finding out how to mix ingredients in the right order is the important part
of imaging.

 Thanks for the replies, this list is great and I appreciate you all
taking time to respond.
So the bit depth on capture determines how detailed the information is
sampled, if an image is sampled at 8 bit changing it to 16 will not
add information that was not originally sampled at that depth.
Although Clayton is saying that he sees less destruction to the image
if he converts 8 bit to 16 bit before applying a fair amount of
adjustments. So while converting doesn't add info it does less damage
to the file when applying adjustments? Amadou, C David what about
image degrading when lots of adjustments are applied?
Thanks again
Jack
