Re: Rough Early Mid-Tones and Highlights

I ran out of Ware's a little while ago and haven't had time to cook up a new
batch so I switched to the classic cyano which I had lot's of on hand. Maybe
as Christina says the coating is too heavy, or as you pointed out it's the
paper. I always brush coat with a sponge brush and usually only use enough
to wet the paper without pooling. By way of comparison, Ware's Cyano II
gives fantastic highlights, great scale and a nicer blue too. The only
drawback to Cyano II is remembering to add the acid and making the damn
stuff -- which is a little more involved not to mention toxic.
