TV studios get a regular tune-up to look good.
by Pete Fasciano, Executive Director 04/20/2025
Every TV studio adheres to a set of essential technical standards for lighting, adjustments to calibrate the cameras, and so on. We do all this so folks at home don’t become distracted by color and brightness errors between cameras during our programs. When we do TeeVee properly we are invisible. Your attention is on the program you’re watching. Your DTV set is simply a window into our TeeVee world. Note that the Spanish words for TV screen can be ‘pantalla’ or ‘ventana’ – a window. If you look outside through a real window the daylight is usually bright and cool. Outdoor light has twice as much ‘blue’ in it as typical warmer-looking indoor light.
Technically:
Outside mid-day light: 2000 footcandles at D65 (6,500 degrees Kelvin) for white. Ordinary Indoor light: 100 footcandles at D32 (3,200 degrees Kelvin) for white.
Your TV screen (window) is set at the factory to match the outdoor light’s white. Why? Because psychovisually we perceive our TeeVee screen as a window, and we expect it to appear just like any normal window. Hence, it has more blue.
This is the Dean College studio. The left display is color corrected to match the studio lights. The right display is the normal cooler ‘blue’ factory setting that we reduce. The two ‘china dolls’ provide white, skintone and black references for adjusting the cameras. All of this techno-nerdy tweaking happens in the day-to-day of operating a TeeVee studio so programs always look perfectly natural at home.
