Second View vs DoF Visualizer

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 ultra-wide 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 panoramic), large format (4x5, 5x7, 8x10), digital sensor sizes, and custom sizes. VIEWFINDER Precise field-of-view matching for any focal length and format. Portrait or landscape, control side of your choice, even upside down. WORKSPACES Design your own bottom control panel. Arrange the controls you use, then switch layouts with an edge-swipe. Start from built-in layouts or build your own per kit. FREEZE MODE Pause the frame on a full-resolution still to compose rise and shift, spot-meter, and measure distance, all without the scene moving. LIGHT METER Select your aperture and the app calculates the shutter speed. EV compensation, hyperfocal distance, auto/manual modes, readout in shutter speed or EV, and whole/half/third-stop increments. BELLOWS COMPENSATION A meter cell folds close-focus light loss into your reading for macro and large-format work, set manually or by LiDAR. SPOT METERING Meter the whole frame, or switch to spot mode to read a small area with a reticle, calibrated against your reference meter. LENS FILTERS Log the ND, polarizer, and color filters on your lens. The meter compensates automatically, and every capture records them. RECIPROCITY CORRECTION 60 built-in film stocks with accurate reciprocity curves, plus your own. Exposures over one second are corrected automatically. Portra, CineStill, Tri-X, Velvia, and more, plus an ECN-2 category. Custom stocks support color or B&W, white balance, and a tunable curve. FILM AND FILTER PREVIEW Simulate B&W film with color filters in the preview and captures, and preview color-film white balance from the loaded stock. LONG EXPOSURE TIMER A countdown timer for long exposures, with a 3-second pre-countdown and a full-screen progress ring. LIDAR DISTANCE MEASUREMENT On iPhone 12 Pro and later, measure the distance to your subject with LiDAR by tapping the viewfinder. On other devices, enter it manually. PARALLAX CORRECTION Compensates for the physical offset between the iPhone and the taking lens, using LiDAR or a manual distance, applied automatically. RISE, FALL AND SHIFT Simulate the movements of a view or technical camera. Offset the crop up, down, left, or right in 1mm steps. COMPOSITION TOOLS Rule of thirds, phi grid, golden triangle, square 1:1, and a custom grid up to 12x12. Bubble level with roll and pitch readout. PANORAMA SIMULATION Preview a stitched multi-frame panorama before you shoot it, and save it as a plan. SHOT CHECKLIST Build a step-by-step checklist per kit and run through it in the viewfinder. One step can fire the shutter automatically when you reach it. CAMERA KITS Save complete configurations and switch instantly. Each kit stores its lenses, format, preferred stocks, workspace, parallax offsets, and checklist. Pick a body and the format picker narrows to the masks it can shoot, with a film-advance guide for multi-format cameras. FILM ROLL TRACKING Track your rolls from first frame to last, so you always know which is loaded and when it was exposed. CAPTURE AND GALLERY Save a reference photo cropped to the exact framing, with full metadata: focal length, format, stock, filters, shutter speed, aperture, ISO, rise/shift, GPS, and timestamp. Optionally export a frame with a data overlay. Edit data, 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

DoF Visualizer — Ten Visual Tools for Photographers Stop guessing what your gear will do. DoF Visualizer turns the math behind photography into clear, interactive diagrams you can read at a glance. Drag a slider and watch the focus zone shift, the bokeh balls grow, the star trails appear. Plan the shot before you press the shutter. Built for photographers who care about why their images look the way they do — from portrait shooters chasing creamy backgrounds, to landscape photographers planning silky water, to astrophotographers timing their exposures, to macro shooters stacking focus on a single flower. TEN TOOLS IN ONE APP • Depth of Field — See exactly what's sharp. Live cone visualization with near focus, far focus, and hyperfocal distance for any lens, aperture, and sensor. • Hyperfocal Distance — Maximize depth of field for landscapes. Watch the in-focus band slide and stretch as the aperture changes, with an animate-aperture demo that shows the effect at a glance. • Bokeh — Preview background blur before you shoot. Adjust focal length, aperture, subject distance and background distance to see how big those bokeh balls will actually be. • Diffraction — Watch the Airy disk grow across your sensor's pixel grid. Find the aperture where diffraction starts robbing detail on your specific megapixel count. • Focus Stacking — Plan macro stacks. Tell it your subject depth and it returns the number of shots and the focus step in millimeters, with every slice's depth of field visualized. • Crop Compare — One focal length, four sensors. See concentric framing rectangles for Micro 4/3, APS-C, Full Frame, and Medium Format, with equivalent focal lengths labeled. • Nodal Rail — Estimate the no-parallax-point offset for stitched panoramas. Save calibrated values per lens and recall them with a tap. • ND Filter — Long-exposure planner. Pick your base shutter and target exposure, get the exact stops needed and the nearest standard ND filter. • Astro — Maximum exposure for sharp stars, using the modern NPF rule (more accurate than the 500 rule for high-megapixel sensors). Stars stay as dots — or sprout trails when you push past the limit. • Sun — Sunrise, sunset, solar noon, day length, golden hour, and civil twilight at your GPS location. Computed locally, no internet required. The on-screen arc even rises and falls with the season. DESIGNED FOR THE WAY PHOTOGRAPHERS THINK • Real lenses, real focal lengths — 8 mm through 1200 mm, the focal lengths actual lenses are built for. • All four common formats — Micro 4/3, APS-C, Full Frame, and Medium Format, with the correct circle of confusion and sensor dimensions. • Interactive visualizations — Every slider updates a live diagram. No number-crunching, no spreadsheets, no guessing. • Works anywhere — All calculations run on-device. No accounts, no ads, no subscriptions, no network required (location is used only by the Sun tool, and only with your permission). • Clean and fast — Native SwiftUI. Open the app, tap a tool, start planning. WHO IT'S FOR • Portrait photographers picking the right aperture for soft backgrounds. • Landscape photographers timing long exposures and dialing in hyperfocal distance. • Astrophotographers calculating their max shutter speed and timing the blue hour. • Macro photographers planning focus-stacking sequences. • Videographers and panorama shooters working with nodal rails. • Anyone shooting at golden hour and needing the times for tonight's location. • Students learning the optics behind their gear. • Anyone shopping for a new lens, sensor, or filter and wanting to see what it'll actually do. Take the guesswork out of every shot. See the physics, then make the photo.
