If either one is off, no matter how clean the key is, the viewer will feel that something doesn’t belong to the scene. Both background and foreground need to use the same lighting angles and have the same perspective. Both setups are critical to the effectiveness of the final product – the background lighting for a successful composite and the foreground lighting to sell the integration of the subject within the composited background. There are two lighting setups for a chroma: one for the background and one for the subject in the foreground. In fact, inconsistency between foreground and background lighting is a major visual cue that will give away a composited greenscreen shot. However, the foreground should be lit very carefully in a manner that will match the composited background. This misunderstanding arises from the need to light the background evenly. The typical misconception is that greenscreen shots must be flat lit. The Green / Blue screen is a very fascinating element for all kind of media productions because it opens the way to a wide imagination and the creation of impossible shots.

There are many options on the market where you can buy a diffuser tube, a plastic or aluminium tube that is usually solid on one side, you then have a cover for this which is the diffuser, a slightly opac white section that allows light through while stopping the strong spots of light to shine through diffusing the light so you get a glow. To diffuse the light you need to cover the LED’s frosting them so that the light is then diffused reducing the spotting being seen. To avoid the spotting effect you need to diffuse the light, and there are many options to do this. Increasing the distance the light has to travel.Placing a thick opaque buffer over the light.Placing a semi-transparent diffuser in front of the light.There are 3 main ways to help diffuse light from your LED light strips, they are: On the internal use light strips the individual LED’s are spaced out, therefore the light from them creates spots, if they were closer then the spots would be reduced and be less like to be seen. However, with the way Hue light strips work, you usually find spots of lights from the LED’s themselves instead of a nice glow which is certainly what you want when running them along kitchen units.
