Lighting Ratios & Inverse square law

Lighting ratios = difference between the key light and fill light

Intensity = 1/d²

These are achieved by distance, diff paper, flags, different lights, dimmer.

Through this exercise, I really felt I learnt how to manipulate light in a cinematic way to get the result I wanted.

the below example is a lighting ratio of 8:1 this was measured on a light meter using an incidental reading using a lumi disk for the key light and the fill (reflector board)
