If Capture One still is like this, I wouldn't really be surprised if there's truth to the other comment here claiming that their current owners are trying to offload them.
It's more like finding the subscription for a CAD program too expensive, and swapping to something more primitive instead. If that offends you, I think you gotta have a long hard look in a mirror some time.
FastRawViewer, DxO, Affinity, Darktable, Capture One. Those are just the ones I personally have installed. There's also RawTherapee, a number of camera OEM-specific tools, and more.
Please recommend these "powerful alternatives", because I have explored the space and found nothing that replaces Lightroom in a way that I find acceptable. Please omit Darktable and Rawtherapee as I've already evaluated those.
In their defense you only spoke about dropping your raw workflow for something simpler not that you looked for a special HDR RAW support.
I know it’s Apple and may not what you look for but does Photomator tick these boxes?
I wasn't looking for RAW hdr, just plain jane RAW support that handles moderately new cameras. I stayed on with the old Lightroom as long as I could, but a) it didn't handle my new Sony RAW files, and b) new Mac versions made it impossible to run.
I've moved away from Apple, as that was the last thing tying me to it. Photomator might be nice actually, maybe a good reason to dust off the iPad - cheers.
