    If I wanted to do my own accelerated stress/aging test at home, who should I talk to about setting something up and doing it properly? Your friends at GEH?

    Did millions of people suddenly disappear? This may have an answer.

    Thank you PE. I almost got it right but you clarified further. I always wondered what the bromide was for. Any indication of the proportions of PF, PB and SS? Thank you. - David Lyga

    The Image Permanence Institute at RIT is the place to go for this type of test.

    Setting up your own is not hard, just time consuming (and expensive from the POV of the materials consumed) if you wish to go that way.

    I think an accelerated aging test of prints and negatives would be worthwhile if I can do it in my apartment. I may see if they can tell me how to do an approximate test.

    Seal some in plastic bags, tape some to the window (facing north if possible) and save some in plastic bags in the freezer.

    Read the R/G/B densities of all sets in the same place every month for a year and plot that.
