Step 6
Add a Levels adjustment layer (Layer> New Adjustment Layer> Levels).

Step 7
For us to properly adjust the settings in the Levels adjustment layer, we need to have a view of the individual channels. To do this, close the Levels tool and drag the Channels pallet outside of its window. The Channels pallet should appear in its own window. Now with the individual channels visible in the channels pallet, double-click on the thumbnail of the adjustment layer to open the Levels tool.

Step 8
To remove the color cast, we need to fix the red and blue channel. We’ll edit the Red channel first. Press Ctrl+1 to select Red from the Channel drop down menu in the Levels tool. Click and hold the middle input slider and drag the middle input slider towards the left. While dragging the input slider towards the left, look at the channels pallet and release the input slider when the exposure of the red channel seems identical to the green channel. I set the location of my middle input slider to 1.80.
Tip: Don’t press the OK button yet.

Step 9
Now we’ll edit the blue channel. With the Levels tool still opened, press Ctrl+3 to activate Blue channel. Drag the middle input slider towards the right and release when the exposure of the blue channel in the channels pallet matches the green channel. I set the location of my middle input slider for this channel to 1.65. Click OK when done.
