I feel that toning for longevity is a good selling point but I would like to keep colour shifts to a minimum. I will have to try some different papers with selemiun to see which changes the least.
I am also interested in trying Sistan due to it not changing the tone of the paper but some people are saying that its not known for sure if it works. Has anyone else got views on Sistan?
Also, is heat sealing prints a good alternative to toning?
Thanks for your help so far.
