I am rethinking my use of 120 color print film these days. I recently received reprints back from a (pro) lab and the colors were quite different from the orginal prints made about a year ago. My understanding is that almost all color labs currently print color film by digital means (e.g. Fuji Frontier) as opposed to optical printing (which is still the rule with true black and white emulsions). Since: 1) I'm told that reversal (slide) film usually scans about as well as negative film; 2) the slide itself provides the printer with a guide for correct color; 3) color contact sheets are expensive and would not be needed with E6 film; and 4) 5x5 machine prints from E6 are really no more expensive than C41, it seems to me that it would be more economical (with no image quality loss) to shoot E6 rather than print film in medium format. Am I missing something here? I'd appreciate any thoughts you may have concerning this issue. Lastly, since I do mostly handheld/candid photography, any thoughts regarding Provia 400F or E200 with regard to color, sharpness, and grain? Thanks very much.
