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. ~m ----- Original Message ----- From: "Loris Medici" <mail@loris.medici.name> To: <alt-photo-process-l@usask.ca> Sent: Monday, March 12, 2007 8:26 AM Subject: RE: Rough Early Mid-Tones and Highlights > Hi Michael, it seems that you have to change your paper (since it > doesn't work good with other iron processes too)...
