while trying to combine light paint images into one, I've tried the mask layer technique just as described in the tutorial video, but haven't been able to achieve good results based on two reasons.
1) I cannot get the mask layer technique to work ( you know subtraction and addicting with the paint brush tool and choosing white or black color ). The subtraction works well, but adding with white doesn't work at all, in fact when choosing white it also subtracts ?? What am I doing wrong ? Are there any tweaks I haven't done ?
2) the other problem I have is while using 5-8 picture. When using - Place - command and importing the desired picture, Affinity doesn't scale it according to the previous picture ( i.e background ). Is there any " auto scale " or alignment feature available ? As combining 5-8 pictures as masks is also a challenge for my old mac - it seems to consume a lot of memory after each command even if I've reduced picture size and resolution. Are there anyone who could give me an advice how to proceed accordingly - obviously I'm doing something terrible wrong.
