Greenscreen recording

At the HWR a video room for a professional video recording is available. There are three different backgrounds (white, grey and green). The so-called Greenscreen is used to insert backgrounds. A few things have to be taken into account to make a green screen shot good.

Preparation and setup

Clothes:

• wrinkle-free,
• no green,
• as little fine-meshed and small squared as possible (prevent moire effect)

Lighting:

• First illuminate Greenscreen evenly, then foreground / subject (The background color should have a luminance of 55% in the corresponding color channel of the camera)
• Best 2 lamps for the green screen at an angle of 45° to the background
• Light for subject is 45° to the camera
• Use the zebra pattering to detect overexposure before shooting without subject

Greenscreen:

• No kinks in the greenscreen
• Subject as far away from background as possible (min. 1 m)
• Observe proportions
• Do not use autofocus when shooting
