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.

PLEASE READ FIRST Second View is not a camera app and does not take photos for you. It helps you frame, meter, and plan shots before you press the shutter on your own camera. The photos it saves are framing aids, not final images. --- Second View turns your iPhone into a precision field toolkit for analog photographers. Set your lens and format, and it crops the iPhone camera to match what your film camera will capture: same field of view, aspect ratio, and framing. Supports 35mm, medium format (6x4.5 through 6x17), large format (4x5, 5x7, 8x10), digital sensors, and custom sizes. VIEWFINDER Precise field-of-view matching for any focal length and format. Portrait or landscape, control side of your choice, preview rotation per kit. AUTOMATIC LENS SELECTION Frames through the sharpest back camera that holds your crop (ultra-wide, wide or tele), so long lenses look crisp. Calibrate each lens with a sheet of paper. FRAMES MODE Rangefinder-style bright lines for every lens in your kit at once. WORKSPACES Design your own control panel and switch layouts with a swipe. FREEZE MODE Hold a full-resolution still to compose rise and shift, spot-meter, and measure distance without the scene moving. LIGHT METER Pick your aperture and get the shutter speed. EV compensation, hyperfocal distance, auto/manual modes, and whole/half/third stops. SPOT METERING Meter the whole frame or a spot down to 1° through the telephoto. METER CALIBRATION Calibrate against your reference meter at several light levels, per lens. BELLOWS COMPENSATION Folds close-focus light loss into the reading, set manually or by LiDAR. LENS FILTERS Log ND, polarizer, and color filters. The meter compensates and every capture records them. RECIPROCITY CORRECTION 60 film stocks with accurate reciprocity curves, plus your own: Portra, CineStill, Tri-X, Velvia, ECN-2 and more. Exposures over one second are corrected automatically. FILM PREVIEW Simulate B&W film with color filters, and preview color-film white balance from the loaded stock. LONG EXPOSURE TIMER Countdown with a full-screen progress ring, on the Lock Screen and in the Dynamic Island, with an optional end alert. HARDWARE BUTTONS Map the volume buttons, Camera Control, the Action button or a Bluetooth remote to shutter, timer, freeze, lens steps and more. LIDAR DISTANCE AND PARALLAX Measure subject distance with LiDAR (iPhone 12 Pro and later) or enter it manually. Parallax between the iPhone and your lens is corrected automatically. RISE, FALL AND SHIFT Simulate view camera movements in 1mm steps, up to your kit's maximum travel. COMPOSITION TOOLS Rule of thirds, phi grid, golden triangle, square, and custom grids up to 12x12. Bubble level with roll and pitch. PANORAMA SIMULATION Preview a stitched multi-frame panorama and save it as a plan. SHOT CHECKLIST Run a per-kit checklist in the viewfinder. One step can fire the shutter automatically. CAMERA KITS Save complete setups and switch instantly: lenses, format, stocks, workspace, parallax, and checklist. Pick a body and the format picker shows only the masks it can shoot. FILM ROLL TRACKING Know which roll is loaded and when every frame was exposed. CAPTURE AND GALLERY Save a reference photo with the exact framing and full metadata: lens, format, stock, filters, exposure, rise/shift, GPS, and time. Export with a data overlay, add notes, group into rolls, and export a CSV log. --- Terms of Use : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy policy : https://secondview.app/privacy
