Some people scan as "B&W neg" and some people scan as "(RGB) positive" then invert in Photoshop or the like. Some people claim that certain scanning software ALWAYS clip if you scan as B&W neg (I believe NikonScan is one of them) so option 2) gives more fully tonal result. 2) Save as Raw/DNG or TIFF/JPG. Note that TIFF is "full quality" where JPG is compressed, but otherwise they are the same in this discussion. Certainly, always save as TIFF rather than JPG as you want the highest quality. If you save as TIFF/JPG, then usually you have the scanner software applying some tone curves and such, so that the image looks pretty good already, then it's minor way in LR/PSD to get to the final image. In this regard, it's rather like having a digital camera saving the images as JPG. If you save as Raw/DNG, then the scanner software will try to maintain as much information as possible, e.g. minimal tone curves and exposure adjustments, so that it can be processed further post-scan. The downside is that it takes a bit more work in LR/PSD to get to the final result. The upside is that if you improve your LR/PSD skills or if better processing software are to become available, then you can go back to the original Raw/DNG file and redo it. *** Personally, right now I scan as B&W neg or save in TIFF format. With medium format /4x5 (I rarely shoot 35mm film any more), there is so much information from those scans that I do not think it's worthwhile to use the other options. YMMV.
