Not really. Flatbeds give excellent consistency in their results and their workflow. Setups with digital cameras vary, require quite a bit of equipment for the serious, and are subject to a lot of variations in the process plus require more post-processing IMHO - from cropping to correction. They can also not deal with dust and scratches like an ICE scanner can.

Not everything is about resolution.

Digital camera scanning folks are enthusiastic and I’m all for it, but there’s a huge amount of value in a simpler process and automation. Look up camera scanning equipment and you’ll see an enormous amount of kit available to optimize these setups. There’s a reason it needs optimizing! :)

I have two slide projectors but haven’t used them since the 1990s because of all the faff and the fact that projection degrades slides. Plus the space required.
