I have some old stock Delta 100 that I plan to shoot tomorrow morning. How can I achieve good contrast & detail without using a filter.Maybe rate the film a little slower?
I would also warn against over-developing. That's the #1 cause of bad negs. Slight overexposure is not criminal, but too much soup usually is! Whatever your developer, take off a good 20-25% from the time given by Ilford, just to be on the safe side.
