I have a a very large collection of chromes and color negatives from the Film Era, without counting, almost certainly in excess of 100,000 of each. Three options 1) commercial scanning; 2) desktop scanner (I purchased one, about $110); 3) DSLR with slide/negative device (have the complete system = K1, Pentax bellows with copy adapter; 50mm f2.8 macro). I have tried the first two and find the following. The desktop unit is pretty good and very convenient IF YOU ONLY HAVE ONE OR VERY FEW SLIDES TO DIGITIZE, and you want the digitized image right now. But, no matter how much I try to clean a chrome beforehand, there are dust spots all over the digitized image. It takes a long, tedious time to get rid of them, half an hour or more of PP to get rid of the dust spots and get the color and contrast where I want it. To do 1000 chromes, 500 hours or more at the computer. Sending off to a commercial outfit,, 1,000 chromes digitzed for 22-25 cents each, returned with reasonable color and contrast (PP tweaking required) and almost completely clean of dust spots. WAY EASIER, WAY LESS PP TIME. I have not tried the K1 + bellows etc. because it is certain the PP time afterward would be the same as with the little desktop converter, with doubtful gain in IQ.
Something I have found. The emulsion of chromes has a texture that doesn't show when projected on a screen, isn't seen when examining a chrome with a magnifier on a light table, but it is picked up when a chrome is scanned and digitized. It shows particularly in very dark areas of a scan. It can be suppressed by keeping dark areas of the digitized image very dark, or by using a noise removal program but at the cost of IQ.
SO: I would strongly recommend commercial digitizing over do-it-yourself
IF you have a very large number of Film Era material you want to digitize. If you have only a handful of images to do, an inexpensive desktop scanner is going to provide IQ pretty much indistinguishable from using a DSLR + bellows-etc and will be much easier to use*. But, expect to spend a lot of time doing PP on every digitized scan you do yourself.
*A problem copying a chrome with a bellows-etc. known about and discussed way back in the film era when that process was the only way to crop a chrome, is getting uniform illumination and correct color. There's a tendency for such a rig to have have a central hot-spot with very strong vignetting. Getting uniform illumination to the corners was difficult. Topcon made a slide copying rig based in part on a big enlarger made by Beseler, one of the Topcon "family." There was a light source that had multi-dial color adjustments, special high-resolution lenses optimized for 1:1 or larger repro ratios, and of course a special Kodak color copy film.
