I implemented "Exposure Fusion - local tonemapping" from @BartWronsk's blog:
bartwronski.com/2022/02/28/exp…
It tonemaps regions of the screen and blends them together, resulting in a smooth, less overexposed look, note the extra detail in the clouds, and sky/land saturation

(I also implemented Physically based bloom, based on learnopengl.com/Guest-Articles…, which means every pixel contributes to the effect based on their luminance, instead of an arbitary threshold. This effect works nicely with localised tonemapping)
I couldn't quite get the guided upsampling to work at a lower mip however, so the final pass is computed at full resolution currently. I suspect I may be handling the original mips incorrectly.
A couple more pics. (Download and flick back and forth between them)
The difference in saturation is really interesting, it shows how much the scene was getting washed out with a global tonemap, due to areas being over-exposed. (Using ACES tonemapping)
