Capture sharp long exposures — no tripod required. With advanced AI stabilization, Light Stack lets you shoot handheld for up to 30 seconds — with consistently sharp, natural-looking results. To help you stay steady and in control, Light Stack offers some unique features: • True-to-Motion Preview: The live preview moves naturally with your hands, giving you intuitive feedback that helps you stay steady. No more fighting to keep a crosshair centered. • Failure Response: If motion tracking is lost, you choose what happens: temporarily pause the exposure, end it cleanly, or keep going without stabilization. No surprises, and no ruined shots when things don’t go as planned. • Full-Resolution Pipeline: Light Stack maintains full resolution from capture to final image. No cropping, and no upscaling to cover it up. Try it free and experience the convenience of Light Stack. --- Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
