Adjustment Layers

Adjustment Layers are one of Photoshop’s most valuable features. They allow you to adjust images without altering the original. Photoshop Elements provides a large selection of Adjustment Layers. In this chapter you will look at the BRIGHTNESS/ CONTRAST layer, the LEVELS layer, the GRADIENT MAP layer and the SOLID COLOUR layer.
Brightness/Contrast layers One of the most common problems when taking a photo is incorrect exposure. Photos that are over-exposed have too much light in them. Photos that are under-exposed are too dark. An BRIGHTNESS/CONTRAST layer allows you to minimize these effects.
A Loading the Sample Photo A photo that is under-exposed has been prepared for you and it will need to be adjusted so that the buildings in it can be more clearly seen. 1
