So I have followed several online tutorials but my copy of Affinity does something quite different. Trying to change the background of a picture. There are different methods of selecting the object/person I want to save (cut out). Then I can cut out the background. Then I can copy and paste to a different background in a different tab - it works, but is cumbersome. HOWEVER, if I open the new background into the same tab as the object/person, then the background fills the person's image (masking over top of the person) and leaving the background transparent. I've tried playing with inverting the image or the mask but that is apparently not the problem. What am I doing wrong? I follow click by click along with tutorials and get different results.
I am also having trouble figuring out layers. I am coming straight from Photoshop CS 1 so I am aware I am behind the times. But there I has simple layers with option to add mask which made sense. Apparently nowadays there are four different types of layers and they can get embedded and float and do all types of weird things. It is unnecessarily complex, but where is the tutorial that explains it?
