This video challenges "makers" to produce a simple Green Screen video using the Do Ink app (available on the iTunes Store).
With this video, you will add a background image and foreground object, and then use the built-in camera source to record a video from directly within the app!
This video challenge also proves that you don't need fancy equipment to record using Green Screen. You can use a tablecloth from your local dollar store, and record in front of your bathroom (if that's the spot with the best lighting)! Now get out there and "make"!
