The free Affinity Photo is a new pro Photoshop alternative for Mac

Petapixel:

Unlike other affordable photo-editing apps out there, which are usually dumbed down offerings with only a subset of Photoshop’s usefulness, Affinity Photo is trying to set itself apart by offering the power of Photoshop in a program that’s blazing fast and ridiculously affordable.

Looks very interesting and for free, there’s no harm in giving it a try.
