A description under each image explaining what it shows would be good. I’m also curious as to why the colors vastly differ among images of the same set (is the anti-ghosting algo doing that?) and why there is strong clipping in these image (since the practical point of tone-mapping is to prevent clipping).

Hi Morgan, those are all tonemapped images from two different HDRs per image set (4 HDRs then, two for the boat, two for the bridge). The first HDR in each set is from merging the 3 exposures without deghosting, the second applying manual deghosting.
You can see “ghosts” in some of the tonemapped pictures.
Color shift is caused by the algo which processes the 3 color channels separately.

@fcomida I’m still confused, as there are photos of: boat boat bridge bridge boat bridge bridge. It would really clarify things if you annotated each image.
Which branch is the code in?

@Morgan_Hardwood In order and annotated. Thank you.
My local branch, I’ll push it soon.
