The Invert adjustment reverses the colors in an image. The brightness value of each pixel in each channel is converted to the inverse value. For instance, a pixel with the value of 0 (black) will be converted to the value of 255 (turns white). Watch our video tutorial to learn more about the Invert adjustment.
To apply the Invert adjustment, go to the Control Panel menu and select Image -> Adjustment -> Invert.
You can also use an Invert adjustment layer (command Layers -> New -> Adjustment Layer -> Invert) which will affect all the underlying layers without changing their content.
