ew things will ruin a marketing video faster than a shot that is either too light or too dark. Yes, you can correct image brightness and contrast in post-production to some extent (more on this later), but it’s better to get the shot right on the day of the shoot than relying on “fixing it in post” later on.
Avoid Conflicts Between Natural and Artificial Light
When it comes to lighting in video, different kinds of light have different temperatures. These color temperatures are measured in degrees Kelvin (°K):
Again, this is a complex topic and could easily warrant its own post, but for our purposes, all you need to know is that mixing two light sources with different color temperatures will make for an unevenly lit shot.
Let’s say you’re shooting an explainer video featuring a member of your team. You’ve chosen an indoor room with good acoustics (more on this later), and you’re ready to start filming. The room is lit primarily by fluorescent lights, but there’s a problem – a large window that lets in plenty of natural daylight.
If you position your subject too close to the window, you could run into a potential contrast in light sources – the fluorescent overhead light with a temperature of around 4500° K, and the daylight, which has a temperature of around 5600° K. This kind of conflict can be difficult to compensate for, and it’s a headache you really don’t need.
Wherever you’re shooting, ensure that your primary light source is even and consistent. If you shoot indoors, avoid rooms with windows. If this isn’t possible, position your subject sufficiently far from the windows to avoid the daylight interfering with your shot.
