Hello,
I want to do contrast and brightness adjustment with the pytorch color jitter. I want the implementation the way you explained it (brightness should be an additive factor and contrast a multiplicative factor.
However I don’t think it is like that in the pytoch color jitter, I did some test :
t_color = torchvision.transforms.ColorJitter(brightness = (0,0))
img = t_color(img)

I did this on the image :

and the result was a black image.
There should be no change if it was an additive factor.
I Don’t know if there is an augment that implement the brightness with an additive factor but if someone know how to do it I would be happy.
PS : sorry for my approximate english, I’m not very good  at it.
