If so, what's your workflow? I have a V500 scanner, a calibrated transparency step wedge, and an 18% gray card. I'm looking for a simple way to gauge density in my black and white negatives. I don't need lab precision, but I do want something quantifiable and fairly consistent. (Ideally I know I'd have a wedge or target on the same film base I was testing, but I'm willing to make some sacrifices.) Thanks.
