In a 24-bit color depth, that means a lot of bits to move around. I just scanned one 35mm slide, and it produced an image file of 5328x3629 pixels, which is between 19 and 20 megapixels. Now I do them a hundred at a time in less than two hours and that includes setup, take-down and stow-away time. Just too slow for the 7500 I needed done. It took him about three minutes per scan and I stopped him after three slides. How long does it take to do just one with a scanner, thirty seconds, maybe? Two- or three minutes? Quite a few years ago, I had a friend who worked in a store where they had a scanner costing several thousand dollars. These methods allow you to snap, snap, snap as fast as you can slip one slide out and another in. You can use those on any camera that has filter threads, regardless of sensor size. Then there are the versions of copiers that screw to the filter thread on the front of any camera. Using a twenty-dollar slide copier mounted on a full-frame, digital body can preserve more detail, from 12 megs on an older camera to 40 megs. I guess that would convert to a 5- to 6-meg image. Scan resolution of 4000 dpi doesn't seem too bad. With either of these setups, you can do about a hundred an hour. There are also the types that screw to the front filter threads of any lens and can be used on any camera with filter threads regardless of format size. They are slow and have low resolution compared to using a full-frame camera body mounted with a cheap ($20 +/- US on ebay) slide duplicator from the film camera era. In my opinion, slide scanners are grossly outdated technology.

Has anyone used this software before? Or is there an alternate, inexpensive software that you can recommend in place of the one we're using? I can get to the area that you plug in the size you want, but it always reverts back to the default.

We've obtained a slide-scanner which we're now using but for the life of me I can't figure out how to change the Scan Size of the images on the program (Cyberview X5) that came with the scanner. Beginner is a bit of an understatement for me - I work at a local archives and we're currently digitizing a selection of our 35mm slides.
