Hi
So I wanna say I really like how Krita has embraced HDR in general but still one of the most important filters don't work with HDR images sadly, Color adjustment curves, this filter will allow fine-tuning the visible image, but once it's applied it removes all the values above one(and below 0) of float HDR images, the same happens with levels and autocontrast, the majority of filters work with HDR preserving all the values though
