The bottom line is that commercial printing, hobby printing and art printing are all very different. Newer folks come in and ask, "Gee, I only have 2 hours, how many prints can I get done?" My answer, "Well, some folks take 10 hours to do a print and others do 10 prints in an hour... it all depends on your skill and where you draw the line."
Hmm, flat prints usually idicate machine (which are getting better these days) while high-contrast prints often indicate a hand job (easier to knock out a decent looking roll of proofs at a higher contrast, slight exposure variences don't tend to be noticed as much).
