Just to update, in case anyone else is watching this issue: I did just hear back from the support team. They say:
We’re aware that our RAW support is a little on the spotty side. We’re working on getting this fixed, but it will take some time to implement. In the meanwhile, we recommend converting your RAFs to TIFs, those tend to open without a problem!
Not a very helpful answer, but at least there was a reply.
My two cents:
I’m a software guy, started as a developer moved up eventually to executive management. I get how the process works. There’s incredible pressure to build new features and products at the expense of technical debt. I love my Topaz products and believe TopazLabs to be a super innovative company, but relying on such an old dependency (and lacking support for modern cameras) makes me fear for the future of the software. Technical debt can take your product crashing down.
