Just shot my first couple of rolls of Efke R25. Developed in Microdol-X 1:1 10min 68F, seems OK. Fixed in TF-4 with a rinse between dev/fix. Wash, then 30sec in PhotoFlo and up to dry. Hmm... what's this? There's something gummy on my film! On one of the rolls, along the edges of the first frame is something sticky, like sticker glue. I pull some off, leave some on. Now that the film has dried the gum is hard. Never seen anything like it before! What on earth is this?! :confused: Looks like a very nice film!
