Talking Green Screen:
When doing special Effects, graphic design and Photo editing, Using a green screen will come second nature to you. When faced with the challenge of the Green Screen the number 1 thing to always keep in mind is your Lighting is KEY. When you have poor lighting it makes it difficult to abstract the background when editing. In most editing software the program is designed to seek out color and tone. When a area is poorly lite in a picture or video, It makes the color range of green vary throughout the background making it hard to completely clear the background. With that said always have lighting to cover the entire area and more. Depending on your subject or lay-out you should have at least five light sources not including your flash from you camera. The flash from your camera is for your main subject in the foreground, because 4 of the 5 light sources will be to evenly light your background.
