ObscuraFlex is a camera app designed for use with the ObscuraFlex™ large format camera viewfinder adapter for cameras including 4x5 Graflex, Linhof, Chamonix, and some vintage Polaroid cameras. The app provides a high resolution live feed of your large format camera's image plane (ie: ground glass) rotated to reverse the upside-down image created by any traditional optical system. When using the camera adapter as a composition and focusing aid for large format film photography the ObscuraFlex™ provides a greater level of detail and clarity than working with a standard ground glass, and with an image that's right-side-up! You can also use the adapter with this app (or other camera app) to shoot stills, video, or reference images to accompany your film negatives.

Based on the legendary XPAN with its unique cinematic panoramic 65x24 images, XP4N turns any scene into a movie set; every shot into a movie still. - Shoot in the amazing 65:24 cinematic aspect ratio - Simulate 8 distinct film types (some inspired by popular film types, such as Cinestill 800T) - NO ADS, NO SUBSCRIPTIONS, NO IN-APP-PURCHASES! - Use all available lenses - Haptic and visual feedback when taking pictures - Use volume up key as shutter button - EV compensation by swiping - Access to the high-resolution sensor (if available and enabled in settings) - Option to save as lossless HEIF files - Saves EXIF and GPS data in photos This app is designed to simulate the cinematic qualities of the XPAN, including emulation of 8 distinct film stocks that are often paired with this camera: NIGHT MODE Based on the Cinestill 800T film character with its moody teal cast and signature "halation" (red halos) around bright spots in the image. BALANCED MODE Inspired by Vision3 250D film stock, with its versatile personality and typical Hollywood-style color and contrast curves. DAYLIGHT MODE Based on the popular Portra 400 film; soft and warm hues and moderate contrast profile. Great for skin tones and dreamy landscapes. GRITTY MODE Inspired by the Lomography Metropolis film, which adds a "bleached" look that is reminiscent of gritty 90s movies. BLACK & WHITE MODES Following the characteristics black & white films, one mode offers a punchy and contrasty B&W style, while the other is soft and dreamy. NEON NIGHT (NEW) Enhances bright spots in night photos and adds vibrant, saturated glows for a "cyberpunk" vibe ETHEREAL (NEW) Classic soft focus mode, without the need to put grease on your lens! XP4N is consciously made to be the ultimate one-trick-pony. A point and shoot camera with only a single button: the shutter button. The internal image processing engine does the rest, based on your preferred film mode setting. (so don't expect deep camera controls... ;-). The resulting images are carefully tuned to have the pleasant silky quality of film and to get away from the oversharpened, hyper-punchy look typical of today's digital cameras.

Verdict

The call

The clearest difference is price: ObscuraFlex at Free against XP4N's $1.99. ObscuraFlex also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 87%). XP4N's advantage is update cadence (every 2 days vs every 5 weeks) and ratings volume (44 vs 2). On ads, in-app purchases and device support there is nothing between them.
