If you mess with this stuff with Photoshop layers, it’s helpful to remember
that when you’re adjusting a layer for levels, use the blend mode luminosity.
When you add a layer for saturation, remember to use the saturation blend mode.
If you don’t, you run the risk of getting “hotter” results that you
anticipated, and they are hard to correct.
