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.

Customer Reviews

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.

Great Chroma Key Grading App


Absolutely love using this app. Extremely useful when setting up large chroma keys. Really missed using it, but now it has been updated and improved a bit.

I am very pleased with this product


I started working with chroma key projects a while back, bought this, fooled around with it a bit, but really didn't understand it.

I have since began to continue my work requiring green screen, took a deep breath, and watched the video a couple of times. I am trying to create a green screen in my bedroom...I have a very small house. Anyway, I was astonished, once I found out how to properly use it, how quickly I was able to get up and running with this. Lighting a green screen is really tricky in a small space, but I actually did it, created some proofs of concept, and now chroma key is not as daunting as it once was. I really honestly could not imagine trying to make a good chroma key without Greenscreener.
