Marc-I believe anyone interested in making the best possible print uses a lot of paper but I have never thought of it as wasting paper. It's just part of an inevitable process. For me the first step is determining the proper exposure for a key area in the print at a relatively low contrast (2 or 2 1/2 filter). Something that has been a great help to me is a test stripper which enables me to make six different exposures of the exact same area on the print. I then make an unmanipulated work print and start the process of considering how to make improvements with burning ( seldom use dodging) and changes in contrast. Maybe I too waste a lot of paper but it sure is fun!
