Hello. I am studying HDRI. So I read your cool paper. Thank you for your work. I am wondering how you read HDR file as ground-truth for training. Also I wonder how do you write result as HDR format file. Thank you for help.

@Hans1984 The pixel value of the .hdr format image is large in the dataset .When saved, the value range is [0,1]. Is the image information obtained not lost ?

As far as I'm concerned, if you don't do quantization or clip, the information won't be lost, they are 16 or 32 bits.
