Hi Steve,
The other night I downloaded the sample photo from Imaging Resource, well what I understood from these images, (you were right) the first image opened in Affinity is the first in the series and is deformed,
that is corrected by Affinity, evidently is able to detect the optics and then make changes, (I did not change the images), so the conclusion seems to be this.
1. Affinity opens and corrects the first image (PixShift), so that being deformed due to the correction, the flap of the flag that appears in the top left disappears in Affinity,
but is visible by opening it with Raw Therapee in the 1st. channel.
2. another note. looking at the images in the transition areas with the light of the sky, it seems me to notice a greater amount of aberrations (not much) than those opened with Raw Therapee.
Of course I excluded PS as it opens the image (in the way we know), the problem remains, just select the individual channels R, G, B to see that the flag takes different positions,
this confirms that you can separate the individual images (ie channels), but you can not recompose them to get the file without the effects undesirable.
Did you try it yourself?
