Hopefully this question hasn?t been covered elsewhere ? so here goes: I have a 72XL and need to get a filter (105 mm filter size 95-105 step-up ring would be b est, IMHO) to bring down the clear blue sky densities on B&Ws. I don?t want t he black skies of a red 25, but not the washed out look of no filter. The ques tion is which filter to get. Will a dark yellow, #15, be adequate considering t he fall off occuring with a front rise (which is what I do in almost all cases)? I actually would like a 041 orange (the B&W number), but fear this would lead to overly dark skies with the fall off. I figure with the fall off, the top of the sky would be as dark or darker than with a red 25. By the way, I wouldn?t u se the center filter for the B&W. Any ideas?
