About

Knurl Camera

Read full description

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.

Pure Camera brings authentic true photography to your iPhone. Images are rendered directly from the iPhone’s raw sensor data through a simulated film process rather than applying a filter to a preprocessed photograph. Most camera applications begin with a processed image and apply color grading. Pure Camera utilizes raw sensor data without multi-frame fusion, Smart HDR, sharpening, noise reduction, or upscaling. The result is a photograph developed through an authentic film emulation—incorporating gamma, color separation, interlayer effects, and grain—using traditional darkroom characteristics rather than post-processing adjustments. This unique approach produces authentic, unprocessed images.. Nine Film Stocks Options range from neutral, accurate profiles to saturated slide film, faded prints, motion-picture stock, and high-contrast black-and-white. Each profile is derived from genuine film properties rather than visual inspiration. Manual Control Users have full control over ISO, shutter speed, white balance, exposure compensation, and aspect ratio. Preferred settings may be saved to named banks and selected with a single tap, or the application may be left to manage exposure automatically. Grain as a Variable Grain is a selectable parameter rather than a fixed attribute. Settings include off, weak, normal, and strong; intensity scales realistically with exposure—subtle at low speeds and more pronounced at higher speeds. Reliable Viewfinder The preview is calibrated to match the final developed image, ensuring accurate framing rather than a generic live-view approximation. Pure Camera is designed for photographers who prefer traditional camera behavior: exposure, focus, and composition are user-defined, while the film handles the remainder authentically. Premium The application is fully functional but limited to the primary lens. Access to additional lenses is available via a one-time in-app purchase with family sharing enabled.

Verdict

The call

The clearest difference is in-app purchases: Knurl Camera at none against Pure Camera's 1. Knurl Camera also leads on iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
