The six most frequently used Photoshop layers for image editing, and how to use them to improve almost any photo Photoshop has many types of layers and adjustment layers available, but there are six that you’ll ind you need to use again and again. Learning how they should be used may seem a little daunting for beginners, but once you’ve got to grips with them, you’ll ind they play a part in the creative process of almost every image you make. 01 LEVELS This should be the irst layer you add to an image, because it fundamentally alters the tonal range of the entire image. Create a Levels Adjustment Layer, drag the Black Point slider inwards until it touches the left- hand edge of the histogram, and drag the White Point slider inwards to the right-hand edge. This remaps the tones of the image to make more of the available tonal range. 02 CURVES Curves is one of the most powerful adjustment layers. An S-shaped curve brightens the highlights and darkens the shadows, resulting in extra contrast. Create a Curves Adjustment Layer and click the middle of the diagonal line to add a central control point. Drag down on the lower part of the line and drag up on the upper part of the line to improve image contrast. 03 HUE/SATURATION This adjustment layer is best used for altering the intensity and brightness of individual color channels in an image – greens and blues in landscapes, for instance. Create a Hue/Saturation Adjustment Layer, click the Master menu and choose the color channel you’d like to adjust. Small changes are usually the most efective.
