How to adjust the enhance degree and contrast degree for over exposure dataset #13

Closed lastbasket closed 6 months ago

Hi, I am training on my own over-exposure dataset. I find that the enhance degree and contrast degree are difficult to adjust and will result in nan in terms of training loss and psnr.

Hi, thanks for using our project ~

Due to I can't get your own data, so I guess that there maybe some problem occurred in the loss function part. Please check the value in the inverse tone mapping loss function, if this is problem, please change it to the original MSE loss function.
