Bartone,
Sorry, but I do[/i] understand! I have 14 years of LF experience myself. Probably not enough yet for old f***dom, but the good basis for future curmudgeonliness. The crucial difference though is that mine is all acquired in the field. Where you might have been able to view your groundglass in the comfort of your studio with an evenly illuminated subject using lenses of 'standard' focal length or longer, my groundglass viewing has been conducted under an uncooperative darkcloth, sometimes in a howling gale or I might have been eaten alive by midges or the man with the beard wants to talk to me about my 'interesting camera' and so on. Plus, wideangle lenses do not evenly illuminate the GG, so composing, focusing, using movements and metering under these circumstances is really a bit of a chore.
Compositional skills are intuitive, brought out by experience. If you are using a state of the art digital imaging device, why would you want to do the metaphorical equivalent of tying one arm and one leg behind your back in the vain hope that this might imrove your compositional skills? As for this science babble about right and left halves of the brain (I am an MD BTW), I simply do not buy it. If yours does not work as an integrated whole, you may have a problem!
