Hi Friends, I'm reading Lambrecht and Woodhouse's "Way Beyond Monochrome" and profiting greatly from it. One point has raised a question, however. Lambrecht says that he makes his test strips on 5x7 paper, which he keeps a stock of for each type of paper he uses. So if he's going to print on Ilford MG IV 11x14, for example, he'll use a sheet from his stock of MG IV 5x7 as his test strip. I've read (in other forums) that some folks will ONLY test using paper from the same batch they are going to print with. If they are printing 11x14, they'll cut up a sheet from the envelope or box they are working from and use that. They say that there's enough variation between batches that it makes a difference. I work somewhat like Lambrecht (I wish I could print like him), in that I keep a box of scraps and cutoffs (all of the same paper type, of course) to use as test strips. Maybe I'm not such a fine-art printer that I've noticed any difference in my work, but I also think if it works for Lambrecht and Woodhouse, that's good enough for me. What are other folks observations and experiences? Have you seen such dramatic differences from batch to batch of good quality paper (like Ilford) that it would make a difference?
