My favourites are from @HIRAM (grungy!) and @Wocket (the light!).
…
Here is my take: gritty and candid.
1 PhotoFlow
→ linear Rec.2020 (no clipping).
2 gmic
→ interpolate unwanted pixels → brighten → grey out chromatic aberration → generate mask for enfuse.
3 enfuse
→ recover highlights.
4 gmic
→ remove alpha and interpolate unwanted pixels from enfuse
output → brighten.
5 pnmclahe
→ local contrast enhancement.
6 gmic
→ recover chroma from pnmclahe output → brighten → crop → sharpen (tone) → resize → sharpen (edge) → vignette (vigrect
; try it ).
