It's a start, at least. At least LR can catalogue 32 bit TIFF files. Better if it could catalogue all 32 bit file formats. Don't care if I can't edit them but cataloguing would be good.
There are some drawbacks with the LR approach. One, it handles only TIFF files which are significantly larger than a 32 bit .hdr or .exr file. As a comparative, I had a 32 bit .hdr file I was looking at yesterday that was about 40MB. The same image saved in TIFF format was 140MB. For anyone who does a fair bit of HDR work that'll chew up hard drive space pretty quickly.
Second, for some reason LR seems to automatically adjust the white point of 32 bit images imported. I'd prefer that they be left untouched and allow me to adjust as I see fit.
Played with some the other day and agree that results can be quite good. Completely natural, which is good.
It's a good first step but there's still a way to go.
@Hans, what do you mean there are no parameters in HDR Pro?
