I will not be able to use the seagull. For some strange reason it holds onto the carbon particles and my carbon prints had a slightly fogged look to them. It drove me up a wall for almost a year trying to figure out what was going wrong with my carbon process -- finally figured it out when I used a piece of Ilford paper and had no 'fog'. I had taken a break from carbon when my triplets were born (taught myself platinum printing instead) and had re-started carbon printing after buying a couple boxes of Grade 1 16x20 Oriental on sale to make some 11x14 carbons on. I know of one other person who has used it with no problems, so I don't know what's up -- but I won't waste anymore of my time with it...a year was enough!
I often visit friends in Hayward (PhotoCentral) -- are you close to there?
