How to Enhance Colors in Photoshop Using Gradients

Do your landscapes look dull? Give them rich, vibrant colors with a gradient!
Landscape shots can often turn out mildly disappointing. What we don’t tend to notice with the naked eye is that the sky is usually a lot brighter than the foreground, yet the camera really picks this up.
Normally, you might try to tone down bright skies using a selection and a Levels adjustment, for example, but you can also do it using a Gradient adjustment layer and Photoshop’s Overlay blend mode.

BEFORE: Note the subtle disparity between the sky and the foreground.
AFTER: Photoshop’s overlay blend mode can give you a warmer overall image.
So why do it this way? Because it’s easy to undo or modify the effect, because it produces a nice, smooth gradation in tones, and because it also enables you to adjust the colors in the photo in a very subtle way. This is useful in landscape photography, for example, when you want to add a warm, rich tone to your pictures. Photoshop has Photo Filters that are designed to do this, of course, but it’s actually quite difficult to get them to produce the same sort of effect.
The Overlay mode is one of Photoshop’s Contrast blend modes. What happens here is that the pixels in the "overlay" layer don’t cover up those in the layer below. Instead, they lighten or darken them (50% grey is neutral).
How does that help here? If you create a black-white gradient, with black at the top of the image and white at the bottom, the net effect of the Overlay mode is to darken the top of the picture (the sky) and lighten the bottom (the foreground).
But if you change the gradient colors so that you’re using a darker color at the top and a lighter color at the bottom, you still get the sky-darkening effect but you can also introduce a color tint at the same time. And Overlay mode is very good at applying tints subtly.
We’ll start our guide by using a "virtual" Gradient adjustment layer.
