I am curious as to how many Deardorff 8x10 owners use a 4x5 or 5x7 reducing back. Indeed, is it "reasonable" to contemplate selling a 4x5 camera, and using the 4x5 reducing back when one wants to use that format? To those with the reducing backs, in addition to how often do you find yourself using the 4x5 back, how do you go "about it"? To be specific, do you "one day" decide to shoot 4x5 ( or 5x7 ), and pursue your photographing with the reducing back already in place, or do you carry the reducing back with you and decide to change formats after seeing a given subject "in the field"? If the latter, might I get a sense of when you decide to use the smaller format. Is the choice based upon "isolating" the subject? Thanks for any insights. Trying to decide if buying a reducing back makes any sense and having only one camera.
