Hi Alex,

"Unaltered image" is something close to what I am interested. Given the parameters that I enlisted, do they look reasonable to get the "Unaltered image"?

Also, only if you have time, would you mind replicating my test by adding "half_size = 1" (see below) and see if the converted image looks correct?

-----------------------------------------
use_camera_matrix = 0;
highlight = 0;
use_camera_wb = 0;
output_color = 0;
gamm[0] = 1.0; gamm[1] = 1.0;
no_auto_bright = 1;
user_mul[0] = 1.0; user_mul[1] = 1.0; user_mul[2] = 1.0;
half_size = 1;
-----------------------------------------

Thanks a lot!
