Oh, these are bad scans. The paper wasn't quite flat, so only the parts that are flat on the scanner bed are in focus. But it's getting late (6:17 am), and I need to go walk the dog, so I don't have time to rescan them right now.
But I LOVED the line drawing of David, and I had to go aquatint the whole thing, and while I like the result, it's not the same drawing at all.
But I'm thinking something is the matter with either the acid or the ground, because here is another line drawing etched for 30 minutes, and the lines are really nice. But if I etch them for longer, the ground disappears between the lines, and it gets all spready.
So I aquatinted this one too. It still needs some work.
And here's the one that I thought should have been black when I over-etched it last week, but wasn't. So this one is aquatinted pretty heavily, with some light areas burnished back in.
