Get ready to revolutionize your cinematography with lighting ratios! While many DPs rely on their eyes to compose and expose their images, ratios offer a more traditional and foolproof approach. By measuring the brightness levels in relation to one another, you can simplify your cinematography and consistently achieve the look and mood you and your director desire. Plus, ratios are tied to genre, so you can use them to create a coherent aesthetic across your entire shoot. Whether you use a light meter or false color and a color-accurate monitor, ratios are an invaluable tool that will enhance the quality of your images. So why not give them a try?
