Light has probably the biggest influence on an image. It doesn't necessarly mean that you need actual lights nor reflectors to create a good image. You just need to be able to expose the camera in a proper way and therefore know the limits of your system. Although there might be a difference in contrast rendering when comparing analog film to digital sensors the process of lighting is almost identical. In fact, some DP's which won an Oscar light and expose exactly the same way on analog cameras as they do on digital cameras.

I did a lot of tests with analog film and digital cameras. It is very interesting to color edit scanned negatives and see how good analog film performs with highlights. I find it interesting to take measurements, do some math and create lighting plans for films.
