I made my return to the darkroom back on New Years eve did some printing and experimenting with selenium toning for the first time. While I was using RC coated paper, I only saw a minimal colour shift but to my eye more detail came out in the image.
Selenium toner renders the residual silvers into an inert state, however there are some drawbacks, one, it stinks really BAD. Two, you are messing with heavy metals so proper protection is required and don't inhale too deeply. I should make two fibre prints and try this process and see what I get.
