I asked this on the LF forum too, but though I'd ask here to see if anyone had any ideas. This weekend, a friend of mine wanted to test his new lighting equipment. I took my 8x10 to his house to shoot some pics, but left my expo disc at home (duh!) I am fairly sure I needed some sort of bellows compensation. I was shooting Provia 100 (metered and exposed for ISO 100), with a 19 in. APO Artar lens. My question is, should I have the lab push these sheets by a stop since I didn't compensate for bellows extension before hand (or can I do anything about it in the developing stage)? I took some snow shots last week on a couple of sheets of Provia (metered and exposed for ISO 100). Would pushing a stop help these images?
