Much better results could be obtained from negatives, however it is difficult to get rid of a red or magenta cast. Increasing exposure in the software eventually reveals some details, but can wash out the highlights in an ugly way. Scanning at 16 bit resolution does not help at all, for this reason, that this particular CCD chip is not capable of producing signal of adequate range, no matter how many bits the following A/D converter may have. Be sure, that your slides are correctly exposed and they don't have dense areas, where you want the details to be still visible. This scanner has some limitations, that don't allow to use it for a serious photographic work, especially when it comes to scanning slides. But as it happens all the time, you get what you pay for. I decided to buy this scanner after reading some enthusiastic reviews. For 35mm film, where every grain counts, a dedicated film scanner is highly recommended! KM is quicker, easier to use and gives more consistent results. It's generally a pleasure to use, especially compared to using a flatbed scanner (like v700) where you have to struggle with fiddly film holders, dust on the glass, focus issues and heavy post-processing. No problems with curling films, the film holders are really well designed. Given its AF capabilities the sharpness is great with very little or no sharpening necessary in post processing. I have compared it against my other scanner Epson V700 (with custom film holders) which I bought to scan medium and large format and even though epson is quite a capable scanner, DSIV that clearly shows its superiority by handling shadows better and resolving right up to the grain structure. I can only say that the scanner is great. I am mainly using Vuescan, which has most up to date drivers for the current systems but have also tried installing Konica-Minolta's software and it's running fine. The are no problems running it on current OS like vista or Windows 7. I bought the scanner just over 6 years ago and it is still up and running.
