I've had a couple of differing viewpoints on this subject. Both came from well known photographers and both print at Reed in Denver. One said that photoshop USM is totally inadequate, saying that the sharpening that one sees on the monitor doesnt match the print, the other saying that USM matches exactly with the print. Both do lightjets and both shoot 4x5 color trannies. I as well shoot 4x5, mostly velvia, southwestern landscapes. I have yet to print anything big. Should i consider an alternative sharpening program like NIK?
