>>4476042Actually I checked your images and none of them is an HDRI. The tiff is 8-bit, an HDRI should be in 32 bits, not sure about the dng but it doesn't look to be 32 bits. Never heard of the program you've used either.
In any case the data is here and the highlights can be recovered, but it's quite noisy (see picrel). When it comes to processing I can't do much other than recovering highlights and removing distracting stuff since I don't know what you were going for.
