I was testing for light leaks my new 4x5 and screwed up the test film by not setting up the fstop back to the desired exposured. It was wide open. I rated the film at iso 100, 1/100s and overexposed from f12 to f4.5. Is that 3 stops overexposure? or a bit less right? I still want to develop the film solely to determine light leaks, so i dont care if the image isnt sharp enough at f4.5. I got access to d-76 and Rodinal. How should I change the times and method of developing to rescue the film? The devchart at digitaltruth says 6-7mins at iso 100 with d-76, 3.5mins for rodinal 1+25 at 100iso. Thanks in advance!
