Mac, I would have to agree with you as you say you; “ I find the process of arriving at the best initial exposure much easier with split grade printing” Basically with four sheets of paper you can nail down the two exposure times and have at least one print with which will be very close to a final dodge and burn. I myself can’t do this with a single filter technique. Yes you maybe able to do it with a single filter, but I also find it takes longer, and lot harder IMHO.
Thanks,
