Knurl is a camera for people who would rather develop the photo themselves. It captures true Bayer RAW: the sensor's own mosaic, written straight to a DNG with none of the computational photography that normally happens on the way. No multi-frame fusion, no tone curve, no sharpening. What lands in your library is undeveloped data with all of its latitude intact, ready for Lightroom or Photos to interpret however you like. THE CONTROLS ARE THE POINT A mode wheel you turn, with the real designations: P for program, Tv for shutter priority, Sv for ISO priority, M for full manual. Every position clicks. ISO and shutter move in thirds of a stop along the standard photographic ladders, on a dial that detents at every rung. Whole stops click harder than thirds, so you can count them by feel without looking. The ends of each ladder are the sensor's genuine limits rather than round numbers, which means base ISO, the cleanest the sensor gets, is actually reachable. Exposure compensation on its own scale, in thirds, with a firmer detent at zero. In manual it becomes the meter, because compensation has nothing left to act on when both controls are already fixed. An AF/MF switch and a focus ring you turn like a ring: relative, so touching it never jumps focus, and marked near to far rather than in invented distances. Three lenses, each at its native focal length, read from the hardware. HONEST ABOUT ITSELF Bayer RAW is 12 MP and does not permit zoom. The 48 MP path would mean Apple ProRAW, which is demosaiced and partially processed, so Knurl does not offer it. When the exposure you have asked for is not achievable, it says so rather than pretending. Your shots go to a Knurl album you can browse in the app, pinch to zoom, and swipe through. Volume buttons fire the shutter. Add the Control to your Action Button, Lock Screen or Control Center to open it without unlocking.
Luxa RAW Camera

Luxa is an iPhone camera for natural texture, expressive color, and thoughtful control. Choose how your photos are captured, explore film-inspired styles, and keep the experience simple—from framing the shot to saving the image. YOUR CHOICE OF IMAGE PROCESSING Choose from three imaging engines: • Process Zero RAW — develop Bayer RAW with Luxa’s own rendering pipeline for a more restrained starting point. • Apple ProRAW — combine RAW flexibility with Apple’s computational photography on supported devices. • Apple Processed — use Apple’s image processing for ready-to-share HEIF photos. RAW and ProRAW availability depends on your device and camera. The amount of Apple processing varies by engine. PHOTOGRAPHIC STYLES Explore looks inspired by Kodak, Fujifilm, and Leica—from warm film color and understated tones to expressive monochrome. Choose a lighter touch or a stronger look with adjustable style intensity. Monochrome styles use their full effect to preserve their character. Add grain with separate controls for amount, size, and roughness. Styles and grain are applied to the finished photo, so you can keep your attention on the scene. CONTROL, WHEN YOU NEED IT Adjust focus and white balance, or use manual shutter speed and aperture where supported by your device and iOS. Stay in Auto for everyday moments, then take more control when the scene calls for it. RAW MADE APPROACHABLE Save in RAW, HEIF, or RAW + HEIF, depending on the selected engine. Keep an original RAW file for editing, a finished HEIF for sharing, or both. When styles or watermarks require a rendered image, Luxa can save a HEIF companion alongside your RAW. THE FINISHING DETAILS Add a clean information-bar watermark with capture details and a signature. Use composition grids and a horizon level to help frame your shot. Open the built-in gallery to browse your photos, mark favorites, and view capture information. Less Processing. More Control. More Texture.
