This is a well built unit with versatile software and I have worked my way through hundreds of 35mm slides, some of which were damaged or faded. The results are not as contrasty as cheaper slide scanners. It does negatives, but alas, only 35, not medium format which would have been a bonus. It didn't always play well with Photoshop Elements 24 and we had some crashes, but that's more about the Photoshop. You don't really need separate editing packages if you use Silverfast properly. It did improve the scratches and eliminated dust. The process isn't the fastest and the slide holder only takes a small number, but all in all, a good piece of equipment for salvaging your treasured memories on transparencies.
