Lighting is often underrated but plays a crucial role in video quality. Even a great camera can produce subpar results without proper lighting, while good lighting can elevate a video's overall look. When shooting outdoors, take advantage of natural lighting, such as utilizing windows and favorable angles. However, when shooting indoors, having solid artificial lighting becomes essential.
Investing in a ring light is a popular choice, and I personally recommend Lume Cubes for their quality. Additionally, having sidelights can help eliminate excessive shadows and provide more control over the lighting setup. Experimenting with different light positions and angles can greatly enhance the visual appeal of your videos.
