Hi guys I'm wondering if you can help me. I was loading a roll of 400iso black and white film into the developing tank when I suddenly received a message on my iPhone that lit the screen up and the film was allready out of the canister and unwound. The iPhone was on 1/3 brightness and approximately 2-4 metres away from the film and exposed for 4 seconds. As soon as the screen lit up, I threw the film on the floor and rushed to turn off the phone which was ontop of the bed. I'm wondering if the film will be totall ruined or to what effect this exposure will have on the developed negatives. And finally I'm wondering if there is something I can do during the developing process to compensate for this? Any response will be highly appreciated
