To start, shoot a sample roll/sheets bracketed in one stop steps more exposure outside in normal sunlight with some areas of deeper shade in the frame... Then develop them normal in your usual developer and see if you have a printable neg on there... There are developers/dilutions that hold the fog down, but not too much if excessive... And there's reducer formulas to cut base fog, but this gets tedious for daily use with a lot of film...

If there's too much fog, restrainers won't help much, as they can cut your EI greatly... And sometimes uneven base fog levels across frame, as edges might have more fogging, etc...

If you plan to scan, there's (more) hope!!!!

Test, test, test...
