Landscape photographers know that overcast skies happen. Those blue/gray tones permeate the scene… and you can embrace and bolster the look. A pale blue cast to a photo adds an amount of calmness, even a bit of a vintage feel.

You can use a curves adjustment to create a pale blue look to your photo. This technique works in any software that has a curves control.

1. Open your curves tool.

2. Switch to the blue channel

3. About 2/3rds of the way up the curve, click and drag upward slightly

4. (Optional) Flatten the curve toward the lower left to leave shadows unaffected

What this adjustment does is add blue (and remove yellow) to brighter parts of the image. The darker areas are less affected. Only small adjustments are needed - less is more with curves.
