    By all means tone your black&white negatives if you want them to last forever.

The most important factor(s) might well be that all traces of fixer are removed, and the any mounting materials are completely archival and free of contaminants of any sort. There are obviously photographers who use a dilute solution of Selenium in order to influence the color of the finished print. Such "toning for color" is not at issue. As is the case with many "facts" about photography, it would be interesting to know of any scientific research that definitely proves that toning prevents degradation-or, has no affect at all on longevity. Selenium toning has become thought of as a "necessary step for longevity", and has been promulgated as "necessary" by experienced photographers who have had such information passed to them by other photographers and books. We have taken such information, perhaps, as being true because of our respect for our teachers and colleagues. However, are they correct? Simply asking for information of a scientific and unbiased nature....not starting any arguments here. Indeed, if it can be shown that Selenium toning is NOT needed for longevity, then another chemical step that can affect the environment, and uses additional water, MIGHT be avoided. Thanks.

    Scientific proof is hard to come by and silver-based photographic research has probably stopped altogether, but one thing is for certain. Some toning is better than none. I'm running a real life archival; test at the moment, and it already shows that a 1+19 selenium toned-print is doing better than its untoned counterpart. When this test is done, I will have more data to compare the effect of Sistan, selenium and sulfide toning.

    I beg to differ. Toning has similar longevity effects to prints and negatives alike.

    Hello Tony, could you please elaborate on that? I mean which toner, dilution, time, paper etc...

    Thanks in advance!

    I'll take that to heart. I've always agitated continuously in fixer, bleach, stop bath, and toners, but not in the developer. But when the print stops moving in the developer, which is usually about every 15s or so, I agitate again, so the print is technically moving the whole time.
    But lately I've started agitating continuously. Frankly, I'm not sure I can tell a difference from my previous technique in the final results. But I may also not be skilled enough to see the difference.

    Thanks, Ralph, for providing such good and accurate advice.

    Well, maybe having to continuously rock the trays was AA's way to justify a darkroom assistant! Must be nice.

    I tone. I use mainly selenium sulphide toner to get better longevity for my prints.
    On some RC papers it does not give any noticeable difference, but some papers like Kentmere VC Select get noticeable brownish-magenta tone.

    Are you toning selenium/sulfide as a mixture or is this a sequential toning effort?
