Figuring out contrast needed
Hi experts,

Lets say I have 2 jpegs, one "original" and one "photoshoped" (but only contrast and brightness were changed). I know the changes were not saved in the meta-data.

Anybody knows how would I go about, just from the 2 jpegs, roughly what contrast/brightness change I have to apply to the "original" to achieve, _roughly_/_approximately_ what "photoshoped" version looks like? Assuming I write a fu script or something...

Thanks, any suggestion will be greatly appreciated...

This forum has been DEAD for a long time and the spammers keep trying to take over.

Save yourself from them and go to https://www.gimp-forum.net instead

As a user, not an admin, is there anything I could have done to make it more obvious that the forum is dead?
