This roll and the next (eps10) are technically interesting. I had apparently treated some of the strips with mercury intensifier, which turns the silver image yellow. I scanned the negs as RGB and then converted the neg image to b&w after turning the yellow channel all the way down and the blue all the way up, emulating the spectral response of print paper. Some edge effects can be seen in places.
Mercury intensifier is a combination of hydrochloric acid and potassium dichromate (corrosive, poisonous, and "acutely and chronically harmful to health" -- Wikipedia). I bought mine in little packets from the same drugstore that provided the rest of my supplies. Another reminder of the very different world of photography half a century ago. It was simply assumed that you were not an idiot -- or wouldn't last long if you were.
