(Random excellence from the web)
There are two very basic lessons of post-processing that cannot be stressed enough: First, in interpreting a photograph as a print there is only bleh, fair, fine, better, better, better, and different: there's no best. (You can quote me on that. Please.) The interpretation an expert settles on will likely be better than the best interpretation a neophyte can come up with, but half a dozen experienced photographer/printmakers could conceivably come up with half a dozen different versions of the same file; it depends on how you think the particular picture works best, how you want it to communicate, and what aspects of it you like and wants to bring out. The second lesson is: You have to see it. Never skip the looking stage of the process.
