Color correction with the curves eyedropper in photoshop…
- Open a photo that you think needs correcting in photoshop.
- Create a Curves Adjustment Layer by clicking on the Adjustment Layer icon in the Layers Palette, and then choosing Curves from the drop-down menu.
- Near the bottom of the Curves Dialog, you will see a row of three eyedroppers. From left to right they are used to set the Black Point, the Gray Point, and the White Point.
- Click on the black dropper to select it. Your cursor now looks like the dropper. Click the dropper once in the darkest part of your image. You are telling Photoshop “This spot should be black.”
- Now click on the white dropper to select it. Click with the white dropper in the lightest part of your image. You are telling Photoshop, “This spot should be white.”
- Now comes the tricky part. You need to use the gray dropper to select a spot in your image that should be neutral gray. This does NOT mean a gray that is exactly halfway between white and black. That doesn’t matter. What matters is that the gray be neutral in color (i.e., its RGB values should be equal). It could be a very dark gray, or a very light gray, so long as it is neutral.
- Click and done. Stunning, istn’t it?
