Previsualization of Zones

This was an interesting (and stressfull) project. we had to use, and show how we used (the red circles) the Zone system. so I had to take a meter reading of certian places, and then decide where I wanted those tones to be in the exposure, and how contrasty the picture needed to be. the first one here is the low key's everything should be from middle grey and darker. I metered the skin tones, and the blacks. the one bellow is the High key, and I metered the skin tones and the whites.
