ok, so here’s what I’ve done.
I have 5 dng frames that I want to stack into an hdr. Here are my 100% foss steps:
1 - Pre-processing each frame- RT - corrected chromatic aberration, hot and dead pixel filters, defringe;
2 - Align frames - Luminance HDR - in the end, saved Mantiuk 08, Ferradans and Drago tonemapping results as 16-bit tiffs;
3 - Mean stacking - Gimp - Stacked the three tiffs saved from Luminance HDR;
4 - Final adjustments - RT - Opened Gimp output stack and did some adjustments.
I’m still not very satisfied with this “final” result:
and this is the result with PS (the same workflow as above, but without RT and Gimp)
I also felt the need for selective adjustments in RT, which I applied, in PS, to the island and the tree
at right.
I also still find my RT version too flat and don’t know exactly what else should I do…
