Most lessons throw every setting at you at once and hope it sticks. We do the opposite, one thing at a time, on real photos you control.
We hold everything else still, so you can see exactly what a single setting does on its own, with nothing else getting in the way.
Drag the slider yourself, across real photographs shot at every step, and watch the picture change live as you go.
The photo and the numbers move together, so the setting finally clicks. No memorising, you simply understand it.
