Many people who use Photoshop tend to make adjustments by going to the Image -> Adjustment menu and choosing things like Levels which you use to change the lighting of the image. Adjusting points on the graph change the lighting.
The problem with this approach is that this adjustment is now applied to the image, so when we go to adjust things like the exposure of the image, which we can do from the same menu, then the changes we make to the exposure are being made on the image we have already adjusted.
There's a better way to to this, by using Adjustment Layers.
We'll revert this image, and then we'll make a new adjustment layer for the Levels. This interface looks exactly the same as the previous.
We adjust the points on the graph and see the changes to the image in real-time.
Then we can add another layer for the exposure. When we make changes, they're applied independently to the image.
We can always come back and adjust these at any time, and we can toggle them on and off when we don't need them. This is a great way to adjust images non-destructively.
