Hi all! I just happened across a collection of my late grandfather's films which contained some 135 Orwo Np 15/Np 22, some polish Foton S and a few rolls of Agfa Isopan F. One of the rolls of Isopan F had the leader folded back which Ive been lead to believe indicates that the roll has been exposed. Since there could well be some images on the film I am very keen to have them developed. I am quite capable developing black and white film - I regularly process tri-x and others. I generally use xtol or rodinal. So my question is does anyone have any tips/experience to share on how to develop a roll of 52 year old isopan f? The massive dev chart on my phone indicates at 40 asa dev times for d76 are around 13.5 mins. What would be the best developer combo to minimise fogging due to age etc.? Thanks for your help.
