I like to use a split filter technique for most of my work which is based on a middle filter , blast of 5 filter and burn with 00filter.
I do not like the 0 and 5 method only

Bob,I don't understand what you mean by " based on middle filter,and blast of# 5".I can under stand burning in with a 00 filter.Is your normal procedure to decide on a middle contrast filter for basic exposure for test prints then correct local contrasts with the higher or lower filters. A very nice set of procedures,some I use already and some are new to me.Thanks

Mike
