![]() And, as I always say, test footage is your best friend. Make it easy on yourself and start off on the right foot at the very beginning with a proper lighting set up. The last thing you want is to wind up in the editing room and notice that your actor is disappearing into the background, the foreground looks grainy or under-exposed, and you have a giant shadow that just won’t key out. Moral of the story, if you are working with a greenscreen, you will want to have a 5 point light set up in order to get the most “key-friendly” footage. The point is, the more light you have to play with, the more interesting your shot is going to be. Use one of your lights with a barndoor, and throw a cucoloris on there with a blue gel and voila! Looks like sunlight coming through a window. For example, maybe you are in a studio, but need to create sunlight coming through a window. If you want to do any sort of mood lighting, or emphasize certain props or aspects in the shot, the more lights you are going to need. Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing two images or video streams together based on col. The wider the shot, the more lights you’re going to need. However, the more people you have in the shot, the more lights you’re going to need. If you have one subject and have them lit perfectly with 3 lights, then don’t mess with it. That’s a basic definition for this popular term. Now, what do you do with the other two lights when you’re not using a greenscreen or any other backdrop in the background? Do you still need the extra lights? Well, the answer is both yes and no. Three-point lighting is a standard lighting technique used in film, television, photography or other artforms for illuminating a subject from three distinct positions of lighting. Place one on either side, but let the beams cross each other so that the light seems to just flood the background. The other two lights you can use to light the backdrop. The backlight can be positioned behind and slightly to one side of the subject, so it frames the subject and is out of the camera’s view. Three-point lighting is a standard and simple method. The fill should be on the opposite side, at a lower intensity, and still at that 45 degree angle from the camera. An easy solution is to use a pop-up green screen around 40 on Amazon or e-bay. With the key being the brightest light, position it at about a 45 degree angle from the camera, facing the subject. The most basic way is to keep the key, fill, and backlight in relatively the same position as you would have them in a 3 point lighting set up. There are a few ways you can accomplish it. So that said, how do you accomplish the perfect lighting situation? And if you don’t light your subject well enough, you will notice them start to disappear into the background once you start keying, because there is not enough definition between the subject and the greenscreen. If you don’t have enough light on the backdrop, those nasty shadows or hot spots will cause you much pain and anguish in the editing process, because they will NOT want to key out. You need to have enough light to light up the backdrop completely, as well as your subjects, especially when using a greenscreen. ![]() If you are using any sort of greenscreen or backdrop in your shot, a 5 point light set up is ideal.
