I think that trial period for Affinity Photo needs to be longer. In a 10 days period I only found 3-4 hours to look into the software and for me it's far from enough to bring the decision for purchase. I only found that it's not fully compatible with Google NIK Collection (Viveza does not work properly), it does not have full screen preview, Elements Organizer does not recognize native Affinity format...
On the the other hand, it looks like I can find a lot more usable controls over the Elements, such as HSL filter, which really made me happy! I just started familiarizing with Affinity masks, and wanted to finalize first image in Affinity Photo, when the trial expired .....
I have no other option but to wait for the next release and a reset of the trial ..
I believe that I am not the only one who's too busy in daily routines to concentrate the trial scope in such a short period.
(I don't like money back guarantee, as suggested by carl123. Normally I never come back to the seller where I had to use this.)
