Halide Mark III brings AI-free iPhone photography with new Looks

If you shoot portraits, care about skin tone rolloff, or want to rescue highlights without Apple’s default processing deciding the picture for you, Halide Mark III makes a real case for changing how you work. Lux is pitching the new release as an AI-free iPhone camera workflow built around Process Zero, its minimally processed capture mode, and a new set of Looks that let you steer the final mood without drifting into the overcooked mobile-photo look.

Halide Mark III arrived on May 27, 2026 and is available in the App Store. Lux says the app is built around three goals: making the best-looking photos an iPhone can produce, keeping the experience batteries included, and staying streamlined enough for both beginners and pros. That framing matters because Mark III is not just a cosmetic update. It is an attempt to offer a deliberate alternative to Apple’s default image pipeline, especially for photographers who notice when a phone has gone too far with contrast, sharpening, or color.

Process Zero first appeared in Halide in 2024, and Lux describes it as a zero-AI mode that skips the standard iPhone image processing system. In practice, that means more natural-looking files and more editing latitude, but with a tradeoff: it works best in daytime or mixed light, not at night. That is the kind of limitation serious iPhone shooters will actually care about, because it draws a clean line between when Halide helps and when Apple’s own computational stack still has the edge.

The biggest addition in Mark III is the new Looks system, developed with Hollywood colorist Cullen Kelly. Lux says each Look was verified thousands of times on real-world reference photos and built as a physically accurate alternative process that takes advantage of the iPhone sensor’s wide color gamut and dynamic range. The launch set includes Valencia for landscapes and cityscapes, Rembrandt for portraits and more even skin tones, Nova for colorful landscapes with smooth peachy highlights, Zephyr for a subtle all-purpose rendering, and Chroma Noir for medium-contrast black and white with extra grain.

Mark III also adds an all-new Photo Lab with Quick Edit for RAW files, so you can test Looks, adjust exposure, toggle HDR, and try film simulations before committing. The app now processes RAW files from several popular camera brands, includes a redesigned camera interface with a Look tile, new aspect ratios, and composition overlays, and still lets you switch back to the Halide Mark II interface if that is where your muscle memory lives. New users pay $59.99 once or $19.99 per year; existing Halide Mark II buyers and current subscribers get Mark III free. For shooters who want a cleaner starting point than Apple’s default output, that is the difference between another camera app and a workflow decision.
