Brightness control #2

Open alterakey opened 11 years ago

Excerpt from message:

Sometimes i try to trace pictures, which have dark areas and it is hard to trace those dark parts. So some filters or brightness controls or something would be nice to adjust your brightness in your pictures. The lock screen brightness helps, mut not enough! Partial brightness control would be awesome, but propably hard to make... Some filters, like negative, or those which turns your image like pencil drawings, or something would sometimes help! All those paint software filtering things would be handy... like after locking the screen, you would have second options to alter the brightness and everything to adjust it for perfect tracing!

From the reply:

Okay, I got it. You'd like to adjust tone level/curve (or apply filters: negative, edge detection etc..) of an image (entire or partial,) regardless of the screen is locked or not. That's right?
