I'm new to Affinity Photo, but as I didn't find the topic, I hope this is the right place to share and ask.
I recently had to work on a group photo with about 20 people. I took 10 pictures of the group in the span of a few seconds to optimize for the chance of good facial expressions (trying to keep the framing fairly consistent).
Then I looked for an easy way to combine these photos into the perfect group photo in affinity photo. This is what I did:
Pre-Work
renamed the photos to 01.jpg to 10.jpg
looked at each face in turn, going through all ten photos and took note which face to use
Affinity Photo
File - New Stack ... - Add 01-10 (automatically align)
Expand the live stack group
for each face in turn
select all stack layers except the face I noted down to keep
use an eraser brush with soft edges, approximately half the size of a face
delete the face area to reveal only the face I want to keep
when done, I had my group shot with the "optimum" face selection
There were some artefacts visible at higher zoom levels, but because this was for a web page only noticeable when you have a direct comparison.
Now to the questions:
What could I have done better or easier?
Is live stack recommended for this or should I just use regular layers?
