I was relieved to see people saying that selenium has no colour effect on Ilford Multigrade RC, I was wondering if I was doing something wrong. I recently saw an example of a picture given 3 minutes of selenium and then the same in blue and the result was wonderful, it didn't say what paper it was though. Anyone got any recommendations? When I tried it with an Ilford multigrade RC not only was there no change due to the selenium, the blue had absolutely no effect at all. Is this a result of selenium's archival effect?
