When printing last night I was a bit puzzled by the filtration needed for a colour negative (Fuji Superia 200 35mm ) onto Fuji paper. (12x16). I was amazed that the print required a zero filtration with the Yellow filter and only 10 with the Magenta. I have never had this before, is it THAT unusual? With a yellow filtration at zero, if the print had still showed to be a little blue could I go further by using the Cyan and Magenta filters to introduce a bit more blue to compensate? As I said, I have never before had to use a zero filter on any print and I have been colour printing for at least 20 years.
