It was 2018 and I thought I had put an Ilford FP4 Plus in the M5 and I used it at 50ASA.
When I finished the "roll" I saw it was an HP5 Plus film inside the camera... "ohhh!!". So, I had this film until 2024 to develop it in a laboratory.
Finally I had it the past year and now I'm scanning it slowly... it's a hard work for the scanner, because it is a very dense film.
