Importance of Layer AdjustmentWritten by Maricon Williams
The special layers in Photoshop that applies adjustment onto its own layer is called adjustment layers. With them, you can adjust color balance, hue/saturation, levels and other essential factors of an image. Adjustment is necessary when an image needs a premeditated change or modification. It quickly and easily enhances photographs and graphics to create an outstanding graphic design. Editing and retouching made easy – that’s importance of layer adjustment. There are two ways to do this. The first is usual adjustment and second is adjustment layers. Adjustment can be created on actual layer itself by going under Image > Adjustments > and then choosing an adjustment. It will not work on shape layers (vectors) thus, duplicate original layer before you make any adjustments. Adjustment layer can be created on top of original. By this original layer is preserved and adjustment layer can easily be discarded. An adjustment layer applies to all of layers under it. If you had 10 layers of a complex design and you selected uppermost layer in layers palette and then created an adjustment layer, change in color balance that you have selected applies to 10 layers. However if you made a selection, then adjustment layer will spread across document on special layer. If you make adjustment on a particular layer, it will only apply to that layer. To do this, simply press Ctrl or Cmd on layer icon and select layer. Create an adjustment layer of your choice and it will apply to your predetermined layer.
