On today’s Tech, No Babel: Using camera control units for live video production

One of the differences between consumer video cameras and professional ones is that in a studio configuration, the shader can use CCUs (camera control units) to adjust aperture, gain, and shutter speed, as well as painting the cameras as necessary.

Unlike the human eye, cameras don’t see light as white, but as various shades. Professional cameras don’t adjust their aperture automatically. In consumer cameras, this is handled automatically, with various degrees of success. Professionals don’t trust automatic systems. That’s where camera control units come in.

A ccu (camera control unit) can adjust the camera remotely so the camera op just has to focus on shot composition, zoom, and focus.

In a professional system, CCUs handle white balance and color correction (painting) too. This means that changes in the light that the camera captures are adjusted for by the shader. Whether that means, re white balancing or tweaking the colors (in a process called painting), the CCUs do the job.

Usually, all the CCUs for the system are located together and a single person is responsible for these controls.
