How to Light a GREEN SCREEN in 4 Minutes

heads up guys having a formative film school today we're here with Carmichael come on guys a filmmaker working with cord or digital they have over 4.5 million views on YouTube Shelley shoot stuff really fast and cinematically and today you guys asked for it so we're going to teach you guys how to properly light a green screen so I'm letting a green screen there are five things to consider what's the first one all right so the first thing you want to consider when lighting green screen is what is your green screen made of ideally it's a painted wall a green sike wall with matte paint and that is you don't want to be reflected correct most of the time you're not going to have that luxury yeah so you're probably going to need a fabric whether it's just a loose fabric like what we use or the pop out circular or oval-shaped green screen I like the oval shape ones because I don't have many wrinkles and they're very portable great but they're most often reflective indeed they are most often reflected and they're very small they generally tend to be small and there's anything about the color too usually you'll be using a green screen the only reason why you probably will be using a blue screen is if your actor has to wear something green normally even if you're wearing just off green compared to your green screen depending on your camera it doesn't matter use the blue screen problem solved now one thing that I will say about both screens is that they tend to be less reflective the kind of blue and is one-third reflective as the color green and human flesh tends to be red skin toned so having them on a green screen tends to makes for a better contrast no matter what race you are second step is you want to light your subject line of your subject has to come first before the green screen because you want your subject to match the scene you're keying them into you want that to be your primary focus if your focus is spending time on perfecting your green screen you're putting your work in the wrong place lighting a green screen is super easy super quick you want your subject to match the scenario they're going in for instance if your character is going to a scenario where they'd have a really strong backlight remember to give them a backlight before you creams from them you can't just do three-point lighting on a character for a green screen and then throw them into that space you know match well let's let's just stop for a second thing why are you green screening them did you mess up on the day was the actor not available it do you need them in somewhere special effects right different world spend time and think about the space you're putting them in how would you light them if they were in that space that way when you do light them on the green screen it's going to be more accurate and just that much more believable when you're looking at the final image so when you're letting your green screen what do you keep in mind get to keep in mind that you want a balanced amount of luminance all over the green screen I think of a green screen as a color picker you want to pick just one color you don't to say all green has to be removed but just you just want to get rid of that one hue and that one lumens value oh great what if you just have one light and you can't light green screen with your legs put the light on the ceiling shoot down and hit the background in the green screen you want to use a flag an envelope or whatever you have and spilling onto your actor that way you stay in control indeed so when you're letting a subject on the green screen how are you looking at the distance on your town in your subject primarily you want your subject to be as far away as you possibly can and what is the reason for that you don't want the green from the green screen to spill onto the subject this is more work that you have to put into post so are there any tools that can help us achieve a consistent luminance value across the green screen most cameras don't have this built-in so you'll probably want to get an external monitor or something like that but you want to use false color okay false color gives you the ability to see the luminance value in different shades of colors so that it's just a easier way to visualize your lighting if you can't get your full green screen perfectly lit yeah make sure the amount of green screen that's outlining your subject or your actor yeah is consistent because then it's an easy key just around them at least and that's the most important part the rest of it if you're not subject isn't touching that part of the green screen it doesn't matter you can always garbage matte that way yeah the fifth tip of outlining in green screen is lighting gigs it's an extension of the second tip which is lighting your subject once you've lit your actor and you've lit the green screen yes they will fit in the scene you're comping them into but there might be elements in that scene that's producing moving lights those elements are moving lights that can appear on your subject and farm the green screens of butter put them into that environment and once you get all this you're good so there's your episode a former film school and how to light green screens with Carmichael record our digital leave us a comment below with a scene from a movie that is green-screen fun most people don't know is green-screen what actually is are we picking the best scene giving out a V screen bs5 which time you launder false color waveform vector scopes there's my plug and keep watching for minute film school subscribe we will catch you guys next time peace Oh you
