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.
