Image Processing 2nd Edition

This new and expanded second edition 100 page guide, takes you through a number of image processing workflows so you can get the best out of your astronomy images using Affinity Photo software.

This is written for the Windows Version, but the techniques used are the same in the Mac version.
The author has not used Affinity Photo with an iPad, so cannot comment on how similar that version works, or not.
