SOME PHOTOSHOP INSPIRATION CURVES/LEVELS AUTO ADJUSTMENTS By Andrew Haysom
There are three automatic tone and colour adjustments available on the Photoshop Image menu, these being Auto Tone, Auto Contrast and Auto Color. The only problem with using these commands is that they are destructive. You can perform the same adjustments non-destructively and with further options using the Auto button on the Curves and Levels adjustment layers. For this article I will use the Curves adjustment layer as my example but the features are identical with Levels. When you press the Auto button in the Curves adjustment layer Properties panel (see Figure 1) the Curves are automatically adjusted using one of four algorithms.
