RE: How many gum layers (Re: ferri sesquichlorati)
" Otherwise, why not just start with an image, invert it and make a negative of any unknown density without a curve and keep fiddling with it until you get what you want in the print."
Well, Mark, that is exactly my approach and it does seem to work. However, having been challenged by recent workshop participants as to why NOT use a curve of some kind I admit that I have been fiddling around with curves lately and have found that the curve that works best for me is a straight line, i.e., no curve at all. So I'm curious. Are there list members out there that DO use curves for gum printing? Might one of them be persuaded to share their curve with me so that I can try it? I'll figure out some way to repay a kind soul for this generosity.
