Charles, I'd need to see the print to say how much to reduce the pigment. As a stab in the dark (so to speak) I'll say if it's really really dark, then try cutting the pigment by half; if it's just sorta dark, then a quarter.

Folks,
Since it is blown highlights plagueing me, I'll try again with reduced pigment. Any guess as to how much? Half? Quarter? Do you suppose I will need a new curve?
Thanks Charles Portland Oregon
