Passing through Utah in mid-September. Plan to shoot 4x5 B&W in Arches NP and Canyonlands NP. Would you use a 270mm Telephoto lens there? My standard kit would be a 75 ,150 and 210 lenses. With the orange rocks and green trees ,will a #8 yellow work well to separate the rock layers or should I use something else. I want to give the orange rocks punch without blocking up the trees and sky. Never shot near Moab ,no experience with the area and it's color palette.
