If you do want your image to to have cool tones it is a good idea to keep those tones to the Shadows of the image, that way your Skin tones continue to look natural. In this photoshop tutorial we show you how to Colorize using the Hue/Saturation Adjustment Layer and then restrict those Colors to the Shadows using Blend If.
Adding Light Effects
When you are photographing into the Sun you have some great opportunities to add Lighting Effects in Photoshop. From a huge Lens Flare to a subtle Color grade the options are endless and each photo will require a different effect.
In this image we use the Gradient Tool to create a glow on the left side of the image. After bringing in the base Color we use Curves to add a bit of warmth to the Lens Flare.
