I will be exploring wet plate photography next week in a workshop setting and have started to read about the process. I tend to be cautious with chemicals and would like to try to stay as safe as possible at least initially and probably long term. We will be doing both negative and positive images mainly using glass. 1. Any input regarding use of only alcohol rather than alcohol/ether for the collodion? 2. Using sodium thiosulphate or ammonium thiosulphate for fixing rather than potassium cyanide? 3. Any reason that Ammonium thiosulphate or commercial rapid fixer (probably in "film strength") is not as popular as sodium thiosulphate as the fixing agent? Is it just tradition? I prefer neutral rather than warm images in general which makes me think sodium or ammonium thiosulphate may be the way to go. 4. I do prefer a neutral image colour rather than warm images? Any suggestions? Thanks. Sincerely, Hany.
