Also, bear in mind that the DSLR is of limited value as a preview tool because the LCD on the back is still rather small and doesn't have the dynamic range or the color accuracy to adequately judge an exposure. What you see is NOT what you get especially if you're comparing it to transparency film. Because of the significant latitude of negative films, you can be off by a bit and still have a workable negative. Bear in mind that transparency films work more like (but not the same as) digital in the sense that if you blow out your highlights, you can't get them back. But the response curves are different, so don't judge your transparency exposure based on chimping. Shoot enough of your chromes and take notes on the exposures so that you develop a sense of what will work with that film.
