I have the latest Affinity Photo installed on a Win 10 machine and was also able to install / register the Nik collection, but the colours in Viveza are completely wrong. As an example see this thread and the included pictures:
Viveza wrong colors in Affinity Photo
I couldn't find any updates regarding this issue. Does anybody know about a fix or is this just a bug which right know renders Affinity Photo for Windows useless for me, as I do a lot of editing in Viveza (and Silver Efex 2, which works fine in Affinity Photo)?
Hi Michael
I have the same problem as you and don't know of a proper fix. However what I have found is that I can get Viveza to work with proper colors by converting the tiff or jpeg to 8 bit and downsizing to no more than about 2000 pixels high. This is very strange and is not very satisfactory as I would rather do my editing on the full res 16 bit file as the master copy. There is a bit of a work around with this though-
Edit the downsized file in Viveza first and take note of all the settings and locations of the control points (a real pain if you have done extensive editing in Viveza).
Open the full res file in Viveza and set up the same control points and settings as before. The colors wont look right but you will find that when you save the edit and exit Viveza, the full res file edit will look the same as the low res edit. In other words, the editing settings do get applied properly, you just cant see them properly because of the wrong display colors in Viveza.
Might be worth trying, particularly for fairly simple edits.
