Mixed up a simple hydroquinone developer and had some limited success with it - Got infectious development but no significant colour shift, although I did get some browns when dipped in selenium toner.
Looking at some at the recipes, several call for paraformaldehyde - Not something that is readily available, but I can get a 10% solution of formaldehyde. Not being a chemist, can I use this as a substitute, and how much would be required if the original formula calls for 30g ?
I have seen suggestion that acetone can be used in place of paraformaldehyde, but some say it is ineffective.
