Important Note:
 This app does not currently remove or key out green screens. It is a lighting tool created to help filmmakers properly illuminate their green screens for optimal chroma keying during post-production. Green screen removal is a planned feature for a future update, but it is not available in the current version. Please do not purchase this app expecting keying or background removal functionality at this time. Perfect Green Screen – Light It Right, Every Time Achieve flawless green screen lighting with ease. Perfect Green Screen is an essential tool for filmmakers aiming to master chroma keying by ensuring their green screens are lit to perfection. This app visually guides you through the process, helping you identify and correct uneven lighting using intuitive gray band overlays. Key Features: 1. Adjustable Precision
Choose your desired level of detail by selecting between 2 and 50 gray bands. For most use cases, 9–10 bands provide an ideal starting point.
 2. Visual Feedback
The processed preview displays a gradient of gray bands representing luminance variation. If more than three bands are visible, your lighting likely needs improvement for an optimal key. Think of it like zebras—only smarter and tailored for green screen work.
 3. Exposure & Focus Control
Lock both exposure and focus to ensure consistent results throughout your shoot.
 A Must-Have Tool for Filmmakers
