Hi,
- Should its data be 16-bit?
Though it is recommended to use 16-bit raw images, 8-bit raw images should be handled as well in the im2double function. - Is it ok if I directly enter a .hdr format?
You should first extract raw image data. - What operations should be performed to get the feeling that accords with the human eye?
This codebase does not include CCM/post-processing operations. It applies wb gains followed by a global gamma operator. If you have the 3x3 CCM values, then you should apply it before this line.
Hope you find this useful.

Hi, first of all, thanks for your answer, it's very helpful to me.
Missed some questions last time
- Our hdr data is 20bit, and the input data in your paper should be 16bit. Will this have any effect? Do we need to perform an automatic exposure operation on the hdr data first?

- Hello, I'm very interested in the work of C5, but I have a question regarding data collection. I'd like to know what kind of camera settings were used to capture these color-shifted images. When I take pictures with my EOS 600D, they appear as normal white, but due to lighting conditions, there is some color deviation. Can this also be considered as a color constancy task? HOT 2

Each JSON file should include a key named either illuminant_color_raw or gt_ill that has the ground-truth illuminant color of the corresponding image).Can you help me ? HOT 1
