How proper light conditions improves the production.
The general advice is that a stronger light is always better when it comes to lighting. It is because when the light is low, the camera’s resolution goes down to compensate, and the picture looks coarse.
You also need to perform a test using your webcam to ensure the lighting is not casting any hard shadows across the speaker’s face. Avoid strong backlight pointing directly into the camera since this will make the presenter appear too dark in the production.
Next level of lighting
A common solution is to use three light sources which create an even triangle where the presenter is standing in the center of the triangle, facing two of the lights. One of the two light sources facing the presenter should be about twice as strong as the other. The light behind the presenter can be adjusted as desired.
If light from various sources differs in “color” or temperature, that is the formal name, and it may result in poorer coloring in the final result. We, therefore, recommend changing light sources to a temperature that matches the ambient light.
Daylight has a temperature of 5600K, and it is a good light temperature to aim for. But if the ambient light is characterized by light bulbs, the color temperature is usually around 3200K, a warmer light. As long as the ambient temperature is relatively constant, the camera often automatically adjusts or can be manually adjusted to give a good, uniform light that looks natural.
