Cameras got sensitive enough to shoot by candlelight, and lighting became more important, not less. Sensitivity removes the excuse; intention is all that is left.
Motivation before instruments
Every light in the frame should have a plausible source in the world of the story — a window, a lamp, a screen, the moon. Audiences forgive stylisation; they notice light with no reason to exist.
Ratios build mood
A 2:1 key-to-fill ratio reads natural and warm. 8:1 reads dramatic and isolating. Change the ratio across a scene and you change how a character is read without a single line of dialogue.
Shaping tools do the real work
Flags, nets, bounce and diffusion decide the quality of light. A single LED panel plus a bounce board and a flag gives more looks than three bare fixtures.
Grade with the shoot in mind
Log capture protects highlights, but a flat file is not a look. Decide the palette on set, shoot a reference frame, and let the colourist finish an intention rather than invent one.
