Green screen is frequently used in both photography and video productions to create an easily replaceable backdrop. It is important that no matter what type of green screen you are using that the green is well lit. In this movie, author Richard Harrington demonstrates how to use the app Green Screener to make sure your green screen is lit well.
- Green screen is frequently used in both photography and video to create a backdrop that's easy to replace. Whether you're using a simple stretchy fabric one like this, a full cyclorama or something in between, it's important that the green is evenly lit and free of shadows, otherwise you make post-production that much harder. Now, to the visible eye, this can be quite tricky. After all, the green is a pretty overpowering color. But there's a great app that helps you visualize your green screen.
I've opened it up here, it's simply called Green Screener, and there's built-in tutorials here to help you, but just tap the Start button, it's pretty easy. What happens here is it's gonna show you information. So I'll just take a little look around the room here, and you can see the backdrop and some of the pools of light. In this case I've purposely left some wrinkles in it, and you can see the problem. We now have the ability to view different levels of detail. If I go to high quality, I can really see the bands.
This makes it a little bit easier. Tapping, I can see that this is currently 84% green. That's 95, so as you tap, you can see how there's different banding within. You can view individual channels, but with green, I'd recommend the green channel. Go ahead and set that also to different qualities, and you can see different levels as you judge. For example, low is a very quick preview and makes it easy to see how even the green is. However, I'll generally work with mid or high for the best judgement, and I find that if I get it close, it's usually pretty easy.
Now, if you want, you can adjust the target. This allows you to tap where it needs to go. And you can even lock the exposure so subtle movements don't vary as much. All right, that works well. Now, this visible information can be helpful as you shoot some of those keys. It's a matter of judgment, and I find that modern keying software has gotten quite good. But if you can minimize the variation and spot where any areas are getting a little bit blown out or getting a little bit brighter from hot spots, well, you'll get that much better of a green screen.
An app like this is just a useful way to pre-visualize potential problems so you can make adjustments to the lighting while you're shooting.
