My question is three fold: What is the best way to scan 4x5 film (B&W) on a flat bed scanner---- do it in grayscale or in RGB mode and convert it to grayscale i n photoshop. Secondly, is it better to use chromogenic film instead of regular black and whit e film for scaning. I use a very good pro lab to develop my B&W films. I now want to switch to T-Max 100. Could I do the film rating test with the lab processing the negatives for me as I do not have the time nor the space to do my own processing and then obta in densitometry readings of the negatives to establish the EI for T-Max 100.
Responses will be appreciated.
