How to Control Color Spills while Chroma Keying

Green screen photography, also known as Chroma keying is extremely popular among photographers who want to capture and produce unbelievable pictures and videos. This cutting-edge technique has helped shutterbugs across the globe to transform imagination into reality. The best part about Chroma keying is that itís not a rocket science; even an amateur with basic photography skills will be able to give unbelievable effects to his work. The only issue that has been haunting the amateurs as well as the pros is how to get rid of color spills. Color spills happen when light reflects from a shiny object that is present inside or maybe even outside the frame. During Chroma keying, color spilling occurs from the Chroma key green screen backdrops. Spilled color casts a noticeable shadow on the subject, especially around her hairs, shoulders, and bodyline. When you use background replacement software for deleting the background, the traces of the green color will be seen around the edges of your subject; thereby questioning the authenticity of your image. Moreover, the green spill from the green screen backdrop decreases the overall quality of your image. Here are a few noteworthy things that you must do in order to control the color spills.

Light your shot appropriately

Photography is not about flooding your subject with a lot of light; itís actually about using reasonable amount of light for appropriately illuminating your subject. The more intensive your lighting is, the more will be color spills; therefore, do not use direct, bright light. Controlling the amount of light and using it judiciously can greatly reduce the color spills that are caused due to reflections from the green screen backdrops.

Stay away from any reflective surface

Things that cannot be removed such as your walls or roof can be painted with black color or covered with black fabric. Black is a good absorber of light and is sure to help you reduce the amount of color spills.
