I find I need to rate it at 25 when developed in Perceptol to get the look I want
Can someone explain this. If I use Pan F and meter it at 25, I've over exposed from box speed to counter the speed reduction of perceptol as several posters recommend.
Question - which times do I then use from Ilfords table? The times for 25 or the box speed of 50? And Why?
