Light is a photographers bread and butter. It’s a skill to get the right kind of light for the picture you are trying to capture.
I’m use to working with one light light below and it can give some great dramatic feeling to your image.
Below I’ve used a fill light, the idea is that your fill light is less powerful then your main as to give shadow but reveal detail.
I’m still practising this but wanted to show you my progression.
Below is a little edit I knocked up.
