Welcome
This app is meant to help you explore a scene by shifting how red and green are represented in the live camera view.
• Point the camera at something you want to compare, then drag the bottom slider left or right to change the red/green balance.
• If one setting makes edges, objects, lights, signs, fruit, clothing, or other details easier to tell apart, pause there and compare the scene.
• Tap anywhere on the preview to focus on that spot.
• Use the vertical slider on the right to zoom.
• Tap the shutter to capture the processed view. It will say Captured. Saving… while your phone saves it.
• Use the bottom-right camera button to switch cameras, and the bottom-left flash button if your device supports torch.
• Open the shelf from the top-left menu for Formula mode or the legacy link.
There is no single “correct” setting — the goal is to find a view that makes the scene more readable for you.
