A bad habit of mine is that when I scan my film, I tend to include as much useful information as possible, without adjusting for photo-specific tonal values.  The result is that the scans are almost like RAW files – lots of information but pretty unpolished.  The idea being, of course, to store the highest reasonable quality file.  However, since I often do my editing in Lightroom, the original files are often untouched.  Instead, getting the end result requires an additional export step, which I find bothersome because I already have enough trouble trying to organize my files.  In the end, I often upload substandard files onto my flickr account (the only one among my photography-related sites/pages that take .tiff files).  Pity, that.
