Affinity Photo Question in Alamy Quality Control and technical talk Posted yesterday at 12:21 27 minutes ago, MDM said: I don't use Affinity but It's very simple Sally as it is similar to Photoshop with fewer options. What they mean with shrinking and enlarging is downsizing and upsizing - that is decreasing or increasing the number of pixels in the image. it has nothing to do with file types. You are probably not going to be upsizing so just use Bilinear when downsizing which is probably what you will be doing most of the time. Ah, thank you Michael! That makes sense. The terms bilinear and bicubic etc were a bit confusing to me.
