I recently acquired a set of 4 rectangular graduated nd filters (2- and 3-stop, hard and soft graduation for each) for use with my 4x5. I am struggling with their use, specifically, getting the transition in the proper place. Even when viewing the ground glass wide open (all my lenses are f5.6) I am having difficulty seeing the transition on the ground glass. And when stopping down to f22 or f32 it becomes practically impossible.
What is your technique? What am I doing wrong? Also, one other question regarding the transition area of the ND filter: When viewing on the ground glass with the lens wide open (f5.6), then getting the transition in the proper place, won't the transition be in a different place in the image after stopping down to say f32 or so?
Any suggestions, tips, or advice is welcome. Thanks.
