Bart is correct,
A while back I used to use Adobe Bridge and I realised that I needed a DAM tool / raw converter that not only worked well with keywords but was also Adobe Photoshop friendly. Currently nearly all my photos are finished in Photoshop.
I had a deep, close look at both Lightroom and DxO Optics Pro. The latter would not provide any information on the internal color space (in fact were very evasive on answering my query) so I did some testing and was indeed able to confirm DxO was clipping colors, exporting as Adobe RGB or Prophoto RGB for further editing in Photoshop meant colors were lost, colors that I could print on certain papers. I spent a lot of time with ColorThink etc to do my testing.
I am interested in alternatives to Photoshop but the editor must be able to preserve the colors captured in camera as I do final soft proofing based on output destination. It would be great if somebody from Affinity could confirm either way if there are any internal color gamut restrictions.
If no internal color clipping and Affinity Photo were to add a HSB color model that would be a game changer for me.
