Dofora: Depth of Field & DOF

How much is in focus at 50 mm, f/5.6 and 10 ft? Where do you focus so everything from the foreground to the horizon is sharp? **Dofora works it out in real time – with a scale that changes the moment you drag a slider. Free, no subscription, no account, fully offline.** 📐 **Depth of field and hyperfocal distance** • Near limit, far limit, total depth and the share in front of/behind the focus – in large, readable numbers • Sliders or exact typing; metres, feet or feet + inches • "Sharp from … to infinity" at a glance, plus a graphic scale from the camera to ∞ 🎯 **Plan like a pro – for free** • Enter what should be sharp (e.g. 3 ft to infinity): get the focus distance and the aperture you need • Fix the aperture or the focus – Dofora finds the other value and shows what stays sharp • Optimal aperture (depth of field vs. diffraction); near edge sharp, far edge soft • Focus stacking planner: number of shots and every focus distance, with overlap – as a list to share 📷 **Works with every camera – including your new one** • Pick your camera at first start, or take the phone camera with one tap • Full frame, APS-C, APS-H, Micro Four Thirds, 1-inch, smartphone, Super 35, medium format, 6×17, 4×5 – or enter your own sensor size. No outdated model list • Save cameras, lenses and setups; load only parts of a setup (just the camera, just the aperture …) 🔬 **Macro and tilt-shift** • Effective aperture and light loss close up, diffraction calculated correctly • Tilt calculator (Scheimpflug): camera height in, tilt angle and wedge of sharpness out 🔎 **Circle of confusion – transparent and adjustable** • Diagonal/1500 (standard), /1730, 0.030 mm ÷ crop, /1000 or your own value – or depending on the aperture (sharp/soft: diffraction and pixel size) 💡 **Good to know** • Full-frame equivalent, bokeh with a comparison graphic, side view to scale with figures, hyperfocal table by focal length × aperture, hold the framing when you change the focal length ⏱ **Exposure tools – included** • Equivalent exposure with notes on depth of field, motion blur and noise • ND filters: stack several, save your own, measure the strength from two test exposures, or find the filter for your wanted time • Long-exposure timer with alarm, time-lapse planner, video shutter and flicker-free times • Stars without trails: NPF rule with your camera's pixel size – more accurate than the 500 rule 🌙 **In the field and at night** • Compare A/B, backup in one file (no account needed), subject size → distance or focal length • Red night mode and a home-screen widget "hyperfocal for my setup" • Quick start, questions & tips and all terms explained in the app – no forced tour ✅ **Verified formulas** Standard formulas after Greenleaf: H = f²/(N·c) + f. Results are checked against published examples (Wikipedia, Norman Koren). 🔒 **Privacy** • Fully offline, no account, no analytics, no access to your camera, photos, location or contacts • Where the law requires it, a form asks for your consent to ads. You may decline – the app works exactly the same, the ads are just less personal or may not appear. Dofora is free – no subscription, no in-app purchases, no account – and is meant to stay that way. It is financed by one small banner at the bottom of the screen (Google AdMob, with your consent where required) – no full-screen ads, no videos, no ads at launch.

New look: refined dark and light themes, glass-style cards, a floating navigation bar and smoother sliders, chips and switches. Calculations and features are unchanged.
