If you are a photographer, you only need 8 shades of grey…

Plus black and white, which gets you to 10. That’s called the Zone System and was a technique forumlated for BnW photography by Ansel Adams and Fred Archer.

Each step is one stop of light, i.e. doubling or halving. Use the scale to ensure that your photo when taken (or processed on a pc) is not only blade midtones greys, but has more contrast.

You can even clip the shadows and highlights deliberately to get more impact. But you will want to preserve detail as well so your whole sky isn’t only zone 10 or your shade isn’t all zone 1.
