Would you please elaborate on the Selenium toning that you do? Iıve run out
of gold toner far in advance of my POP and Iıd like to use the rest. My
experimentation with POP and selenium toning turned the paper completely

I have very recently started using POP paper, here are a few observations:
1. Toning is (near) vital with this paper. Without toning the result is a
strong orange/brown which does not suit too many images, and exposure times
may be excessive due to bleaching in the fixer.
2. Very different results, particularly in image colour, but also in
contrast range, exposure requirements and possibly tonality can be obtained
using different toning strategies. This is a benefit (wide range of possible
results) but also may be the paper's achilles heel (difficult to achieve
consistency due to toner exhaustion).
3. The "classic" toning involves gold toning before fixing. This reduces the
bleaching effect, so keeps exposure times short. I have found it to give
cool tones in the highlights and brown midtones and shadows at short toning
times, up to overall cool tone with longer exposure times. Dmax with this
toning is around log 2.1.
4. I have tried palladium toning but wasn't happy with the results (some
prints failed to clear in the highlights, and it was hard to achieve a high
5. Selenium toning (using dilute toner) after fixing works quite well,
giving a more neutral colour (slightly warm highlights, slightly cool
shadows). The bleaching effect in the fix is more significant, so exposure
seems to be three times that required for gold toning before fixing, this
does still give a good Dmax however.
6. Care needs to be taken not to handle the paper, I use cotton gloves and
process in one tray to avoid handling during processing.
7. The only strategy for contrast control is to change the toning. This may
be a problem for you if your nagatives are fixed, the negative contrast and
characteristics might not suit the paper. The only thing to do is to try it!
