Plot Multiple Curve Points In Just One Click
We showed you how Photoshop will plot a point on the curve for you if you Command-click (PC: Control-click) on a color in your image that you want plotted. However, there’s a power tip that we waited until now to share—if you add the Shift key, making it Command-Shift-click (PC: Control-Shift-click), Photoshop will add a point for that spot on all the color channels for you. This works in both RGB and CMYK modes.
