Reversal film has much more advantages than the outstanding and unsurpassed quality with projection:
- finer grain than colour negative film (because the bigger silver-halide crystals are removed in the reversal process and the final image is build by the finer / finest crystals)
- higher resolution
- better sharpness
- better versatility:
you can hold the slide just at a lightsource to view it, it can be viewed with a slide-viewer, with a loupe on a light box, it can be projected, you can make direct optical BW prints from it with direct positive paper, you can scan it and make excellent prints from the scan.
With negative film you just have only two options: Scan and print.
- in lots of cases you have lower overall costs, because after development you already have a finished picture; with negative film you always need either an additional scan and / or print. And both are expensive if you want quality.
All is true, however quality scan of slide is not something you can achieve cheaply - dmax of affordable scanners really sucks, contrast management is difficult, not speaking about getting "true colors" in the scan (so it matches what you see in the slide).
