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.
