Well, well, well, after wondering why some of my prints had been a bit of a worry with the aquatint, I realised that the attractive speckly effect on them was because of the interference of grease and rosin. So, after a bit of expert guidance I have started gently tickling the plate with Flash Lemon All Purpose Cleaner solution and a big soft brush. Now I'm starting to get accurate effects on my etchings, and lots of stress has been removed.
Both prints: Levens Hall, Cumbria, UK. 30x20cm aquatint
