I too have been following this with interest and it HAS made me rethink what I've been doing, I often use dodge / burn on masked selection areas, but only ever in highlight / shadow modes, never tried the midtone method, it DOES seem to reduce posterisation and grain. One point, however wonderful dodge/burn and curves may be, how do you set your black / white points??? I dont get this, my scans / digital images nearly always have unclipped headroom at one or both ends and I thought I had to do this via level setting. Does on do this on a global basis to the image first and THEN play with the other tools? Thanks for clearing up....
