How to Adjust Photo Saturation (for a Natural Look)
Also, if you want to increase or decrease the color saturation of an object (e.g., the sky) or area of the image, start by selecting the area you need to modify and isolate it in a layer. Then, apply saturation adjustments only on this layer. In Photoshop, the saturation adjustment is in the same panel as the hue and lightness adjustments.
