What do we want to avoid when planning our lighting for a green screen shoot?

When planning lighting for a green screen shoot, it is crucial to avoid hot spots or shadows on the green screen. Hot spots are areas where the light intensity is significantly brighter than in other areas, which can lead to uneven color keying during post-production. Shadows can create dark patches that complicate the extraction of the subject from the background, resulting in artifacts or unwanted edges that can detract from the overall quality of the composite image. Proper, even lighting across the green screen ensures that the keying process can be performed smoothly, yielding a clean and professional result.

Maintaining consistent and even lighting prevents these issues, allowing for better keying and making it easier to blend the subject with different backgrounds later on.
