Get amazingly perfect green screen with Green Screener.

See demonstration video at

For good chroma keying, green/blue screens must be extremely even, or fine edge detail like hair and transparency starts to become blotchy, which is the hallmark of bad green screen.

Invented by Per Holmes, creator of the Hollywood Camera Work training, Green Screener is a new kind of tool for lighting a green screen that breaks your green screen up into bands, so you can easily see how to light it.

Whether you're working on a $100M blockbuster or shooting green screen in your basement, Green Screener will raise the quality of your green screen to a new standard.

Excellent, PLEASE read before buying

This is an app to help you perfectly light up your green screen, THAT’S ALL IT DOES. This does not do any video work. It’s just a tool to check luminance levels all over your green screen.

Ok, with that out of the way, this app is excellent. I would never try to set up a green screen without it, and would never shoot anything before having checked the green screen with this.

Thanks for the iOS 11 update!

I used this app a lot until my upgrade to iOS 11 rendered it incompatible!

Very happy to see it updated for iOS 11 because it I helps tremendously in getting evenly lit green screens which leads to very easy and clean keys both in post (after effects, iMovie, etc) or real time! (Xsplit, open broadcaster, etc.)

To be clear this is a film makers setup tool. It is not for doing the filming/keying itself.

Works as it claims

This app does exactly what you need and makes the process a million times easier. I just started green screening. So this changes everything. Sorry to all you morons who didn’t do your research before purchasing. There’s a lot of scary dumb people in the world as you can tell by the one star reviews.
