ChromaLens vs Backdrop

Transform how you see color. Reveal faint or hard-to-see details in the world around you using just your phone or tablet camera. ChromaLens is a camera app for iOS that acts as a “magnifying glass” for color, making subtle hue differences and contrasts more visible. Using the live camera on your iPhone or iPad, it lets you explore color relationships as you move freely through your environment. Unlike a typical image filter, ChromaLens uses advanced color remapping that adapts to the color relationships within each image or video. Rather than applying preset styles, it responds to the environment, revealing subtle patterns and unexpected details even in familiar scenes. Whether you're conducting visual analysis or simply curious about how color behaves in the world around you, ChromaLens offers an intuitive way to explore beyond ordinary perception. Record color-remapped video in real time. Already captured footage? ChromaLens lets you process saved videos too. Working with still images? ChromaLens captures and loads high-resolution stills and lets you apply the same color transformations from the video pipeline. ChromaLens’ rich, intuitive user interface makes it an ideal choice for color exploration in the field. Novice users can quickly see meaningful results thanks to its native Apple camera feel, built-in presets and responsive color sliders. Advanced users will appreciate a wide range of professional features, including color pre-processing filters, multiple process modes and color spaces, custom presets, in-app image library, and more. ChromaLens supports a wide range of uses, including: * Field documentation of faded or weathered subjects, such as rock art, murals, and historical surfaces * Artistic and experimental photography and filmmaking * Everyday exploration of color in natural and built environments Inspired by Jon Harman’s DStretch software, ChromaLens implements a modern, Metal-accelerated version of the decorrelation stretch technique developed for scientific image analysis in the 1990s. After the 7-day free trial, a one-time purchase is required to unlock continued access to all app features.

Pick a Look and the camera changes. Point it at a street and the street is already painted in oil, or broken into dots, or drawn by hand. You are not previewing a filter. That is the picture, and the shutter keeps it. THE LOOKS Brush. Painted stroke by stroke, coarse to fine, as you move. Mosaic. Rebuilt from its own colours. Cells split where there is detail. Drawn. The world drawn instead of photographed. Flat colour, inked lines. Matter. The picture as a field of grains that drift and settle. Fur. Combed strands that follow what the camera sees. Dither. Tone traded for dots on one fixed grid, nothing in between. Halftone. Print dots on a square or hex grid, in four shapes. Fluted. Seen through ribbed glass. The world arrives in strips. Water. Refraction and caustics, the scene read through moving water. Code. Digital rain over katakana, lit by whatever the camera sees. The list grows. New Looks arrive in updates. TAP OR HOLD Tap the shutter for a photo. Hold it to record, up to ten minutes. Video renders in the background at full quality, one frame at a time, using the exact settings you shot with. TUNE ANYTHING Every Look has its own knobs. Size, grain, relief, speed, depth, whatever that Look actually has. Drag the handle at the edge of the screen and the picture changes under your thumb. Tap a knob to put it back. BRING YOUR OWN Choose from Photos to run something you already have through a Look. For video, trim it first, pick the frame, then render. NOTHING LEAVES YOUR PHONE No account, nothing to sign in to. No servers. What you shoot sits in the Shelf on your device. Saving a copy to Photos is a switch, off until you turn it on. BACKDROP PREMIUM Dither, Water, Halftone and Drawn are free, and they record video too. Premium opens every Look, including the ones added later, and takes the Backdrop mark off everything you shoot.
