In summary the OP there wants to know how to expose and develop film if the intended result is a scanned image. He/she doesn't say so explicitly but I assume that OP wants to know about differences from standard exposure and development.
Scanners forgive so much more than when doing darkroom printing. You can get decent results from underexposed negatives with scanning. So if you just expose "normally" then with scanning you shouldn't have any problems. Of course film has its own limitations for capturing the brightness range of the subject - as any other media have too ..
hi philburton
it depends what "normal" is for whoever is doing the processing. its like a "normal" lens, its different for everyone.
if normal processing is a little on the thin side not heavy contrast then process film normal, if it is not, make thin and not too contrasty
( like a film processed in a vit c developer ) one's new "normal" for using a scanner. my normal is between dense and bulletproof.
as usual YMMV
Alternatively, I have found it easier to optically print rather than scan over-exposed and over-developed negatives.
There is a lot of latitude built into both processes. The negative that leads to this (often shared here) image is visually very thin, but it prints or scans really nicely:
Thinner negatives (in black and white) tend to produce better scans because more of the tonal scale is placed in the high bit depth portion of the scanners digitization process, which leads to lots of discrete samples to work with, assuming you know what to do with them. Dense negatives tend to produce better analog prints.
