I do use a sheet of paper to do strips of different exposure increments. I should also mention I am contact printing 5x7 negs. I do use the ilford charts to determine the color head settings for a particular grade. I also have a color densitometer from a noritsu. Is there a way to use it to determine the contrast of the negative?[ QUOTE=cliveh;1361355]What you may try is spending a few months/years with the filtration turned off, just concentrating on print exposure and try to adjust your negative exposure/film development time to get something you are reasonably pleased with. Then when you start using contrast control again you won’t be too far away. Also when you mention test print, do you mean test strips of exposure increments? (saves lots of paper).[/QUOTE]
