Thanks Phil,
Another question I have is about the masking of the step tablet with the brown paper, as you recommend in your book. You instruct to mask the step tablet with the brown paper, to a 4" x 5" negative size. My step tablet is already the size of a 4x5 negative, so there is no room to mask it, and fit it into the negative holder. I plan to project it onto a 4' x 5' strip of paper, so it will probably cover most of paper strip. Is it still necessary to mask the step tablet so that there is some portion that receives the filtered light through the translucent paper?

Fred
