Example Content: Adjustment Layers – Photoshop The Beginners Guide Vol 24
Although there are many editing options in the Image > Adjustment menu, they all have one thing in common. When you apply them to an image the effect they have is destructive, because they discard information from the original image. For example, if you apply Curves, the Hue/Saturation, then add a Photo Filter effect, that’s three operations that have discarded information, each one degrading your image quality. If you apply an operation repeatedly, such as multiple Curves corrections, you’ll actually be able to see the degradation.
The only way to undo the damage done by these modifications is to revert to an earlier version by using undo or the History palette, but that also undoes all your subsequent editing as well. This degradation is much worse with 8-bit than with 16-bit images, since there’s less information to start with.
It’s impossible to avoid this image degradation altogether, but by using Adjustment Layers we can reduce it as much as possible. Adjustment Layers sit above the pixel layer in the stack, and their effects are applied in real time as the layers are displayed. That way if you change your mind about an effect, or wish to change it after it has been applied, your alteration doesn’t have any further effect on the layer below it, and the image degradation isn’t applied until the layers are merged when flattening the image.
You can apply Adjustment Layers in several ways. First, you’ll find a list of available layers in the Layer > New Adjustment Layer menu. Second, if you have the Adjustments palette open (it’s open in the default interface workspace) you can click on the button for the layer you want to apply. Third, you can click on the middle button at the bottom of the Layer Palette. All of these offer exactly the same list of options and produce the same results.
