HDR reconstruction is imperfect

[hbardak]

Hi,

First, thank you so much to have ported this to comfyui.
I was wondering if there is a way to improve the High Dynamic Range reconstruction.
The generation of each exposition is slightly different and thus creating ghosting and artefact when looking more closely.

There are some work to reconstruct HDR images from LDR sources using

https://github.com/gabrieleilertsen/hdrcnn
https://github.com/alex04072000/SingleHDR
https://github.com/sharif-apu/twostageHDR_NTIRE21

Would it be worth investigating ?

Thanks

Flux-HDR-360.json
Take a look at this one
Then this can help reconstruct HDR exposure from 3 PNGs correctly

Check this out, this is perfect solution

To get perfect result play with HDR algorithm and exposure adjust in "LuminanceStackProcessor" node

Thanks !
I'll have a look
