Light Leak Effect - Online Add Retro Lens Flare

A light leak effect simulates unintended light entering a camera body, creating warm, organic flare patterns on film or digital images. It adds a nostalgic, retro aesthetic reminiscent of vintage film photography and lo-fi cameras from the 1960s-1980s.

Screen is the most popular and natural-looking blend mode for light leaks, as it brightens the underlying image without affecting pure black areas. Lighter/Additive creates more intense, glowing effects. Overlay and Soft Light add contrast and subtle warmth. Experiment with different modes to find the perfect mood for your photo.

Warm colors (orange, gold, amber) are classic choices that mimic sunlight leaking into a film camera. Red and crimson tones evoke darkroom safelight accidents. Cool tones (cyan, violet) create a more surreal, cinematic look. Match the leak color to your photo's mood — warm for nostalgic portraits, cool for atmospheric landscapes.

No. The preview canvas renders at up to 1000px width for smooth performance, but exports use your original image at full resolution. Download as PNG for lossless quality, or JPEG/WebP for smaller file sizes with minimal quality loss. Your original photo is never modified — all processing happens in your browser.

Light leaks work beautifully on portrait photography, golden hour shots, vintage-style edits, street photography, and travel photos. They add warmth to muted images and enhance the nostalgic feel of already-warm scenes. For best results, use photos with some negative space near edges where the leak can shine through.

Absolutely! This tool is fully responsive. On mobile, the preview stacks above the controls for easy one-handed use. You can upload photos from your camera roll, adjust parameters with touch-friendly sliders, and download the result directly to your phone. All processing is done locally — no data is ever uploaded to any server.

Rotation shifts the leak source around the image perimeter (useful for single-corner presets). Size/Spread controls how far the light extends into the frame — lower values keep the leak tight to the edge, while higher values spread it across more of the image. Together, they give you precise control over the leak's placement and reach.
