What Halide Mark III Is and Why Its RAW Lab Matters
Halide Mark III is a professional iPhone camera app that combines manual controls, a built-in RAW photo editing lab, and film stock simulation so photographers can capture, refine, and finish images without leaving the same interface. Traditionally, RAW photo editing demanded a desktop workflow, with files shuttled into complex software before any serious color or exposure work happened. Halide’s new Mark III release aims to move that entire process into your pocket. RAW Photo Lab lets you open DNG and ProRAW files inside the app, make quick or detailed adjustments, and export finished photos without relying on a computer. At the same time, the redesigned interface trims clutter, keeping focus, aspect ratio, and lens selection close at hand while tucking advanced settings into cleaner menus for a faster, less distracting shooting flow.

RAW Photo Lab: Desktop-Style Editing on iPhone and iPad
The flagship addition in Halide Mark III is Photo Lab, an integrated editing workspace built around RAW photo editing. Instead of bouncing images to another app or desktop software, you can open DNG and ProRAW files directly in Halide, then adjust exposure, white balance, micro-contrast, grain, halation, and more. There is a Quick Edit pane for rapid tweaks, plus deeper sections for photographers who want fine control over color and tone. According to Lux Optics, Photo Lab even has beta support for importing RAW files from standalone digital cameras, letting you process those inside the same interface. On iPad, the editor expands into a two-panel layout that makes it easier to compare tools and results, turning a tablet into a compact, touch-first alternative to classic desktop workflows.

Film-Inspired Looks and a New Simulation Engine
Halide Mark III’s film stock simulation comes to life through Looks, a new system of analog-style presets that reshape the character of your photos at capture or during editing. Built with Hollywood colorist Cullen Kelly, these profiles run on a film simulation engine that factors in grain, halation, contrast curves, and color separation. Options such as Valencia for saturated landscapes and cityscapes, Rembrandt for portraits, and Chroma Noir for high-contrast black-and-white photography give you distinct starting points with specific tonal personalities. Engadget notes that Halide Mark III includes five new Looks alongside Process Zero, the app’s zero-processing option, and Apple’s default image pipeline. Every Look supports HDR, so highlight and shadow detail is preserved on modern displays, and you can tweak these presets inside Photo Lab to create custom variations that fit your style.

Redesigned Interface for Faster Shooting and Editing
To make RAW photo editing part of everyday shooting, Halide Mark III redesigns its interface around a smoother flow from capture to completion. The app borrows from Apple’s Liquid Glass design language, with translucent panels and clearer separation between core and advanced controls. Focus, aspect ratio, lens picker, and composition guides stay visible on the main toolbar, while more technical settings move into simplified menus. A new golden ratio guide joins existing framing tools, and Mark III introduces Shutter Priority and ISO Priority modes alongside an analog-style exposure meter for more precise metering feedback as you compose. Long-time users can still return to the classic Mark II layout from settings, but the new design puts a premium on quick, confident changes so you spend less time digging through menus and more time responding to the scene.

An Integrated Workflow That Keeps You in the Camera
By blending capture, film stock simulation, and RAW editing into one iPhone camera app, Halide Mark III encourages a more integrated creative process. You can shoot in ProRAW, apply a Look like Nova or Zephyr for filmic contrast, and refine grain or color in Photo Lab without exporting anything. The same tools scale on iPad, where the expanded layout turns the device into a compact editing station. For photographers used to splitting work between a camera, mobile viewer, and desktop editor, this means fewer steps and quicker feedback on creative decisions. Halide Mark III is available as a free update for existing purchasers and subscribers, while new users can choose between a yearly subscription of USD 19.99 (approx. RM93) or a one-time purchase of USD 59.99 (approx. RM276), making pro-level RAW photo editing more accessible on both iPhone and iPad.
