If you want details in the shadows you can either meter for the shadows, use a speed increasing developer (Diafine, DD-X, etc...) but meter for the film speed in this case 100ASA,a blue filter can reduce contrast and increases fog on foggy days, but you lose speed. split grade printing a few second grade 0 or 1 and the rest at grade 3 or 4, use a lower paper grade 11/2 or 2 instead of 3. If you scan lower the contrast setting on your scanner or tell the scanning operator to do so.

Good luck
