1 SEE re d
Browse to curves_start.jpg. Open the Levels & Curves panel. Set the drop-down menu to Red. Place an anchor point in the middle of the Curve. Drag a top-right point upwards to lighten the red highlights. Drag a bottom-left point down to darken the red shadows.
2 GO GREEN
Select the Green channel from the drop-down menu. Create another S-curve by placing three new anchor points. By darkening the Green channel’s shadows we reduce the amount of green in these darker areas. Lightening the green highlights creates a more cyan sky.
3 FEEL BLUE
Select the Blue channel. Click to place an anchor point in the middle of the Curve. Place a point in the highlights at the top-right and drag it down to reduce the strength of the blues in the brighter areas. This enables the Green channel’s highlights to become more dominant.
