About this app
Your new camera stops being a mystery. LightWise combines precise photography calculators with a short photography course: work out what you need, understand why, and shoot with confidence in the field. Everything works offline, without an account.
13 TOOLS FOR DIGITAL, FILM AND PINHOLE
• Depth of field: near and far limit, hyperfocal distance and background blur, with a live preview of the scene
• Equivalent exposure: aperture, time and ISO that give the same exposure
• Exposure comparison: up to four settings side by side on one EV scale
• ND filters: exposure time with filters, and which filter you need
• EV and Sunny 16: typical scenes and Sunny 16 for your ISO
• Timer and stopwatch: a countdown and a Bulb stopwatch that counts in EV
• Astro: the longest exposure without star trails (500 rule and NPF)
• Timelapse: frames, interval and video length
• Film reciprocity: the corrected time for long film exposures
• Pinhole workshop: pinhole size, exposure, angle, scale and zone plate
• Angle of view and framing, Format equivalence and Diffraction
Save your cameras, lenses, films and ND filters in Gear and every tool works with them. Change the aperture in one tool and the others already know.
PHOTO PLAYGROUND: TAKE THE SHOT WITHOUT A CAMERA
Turn the aperture, shutter speed and ISO and see right away whether the picture comes out dark, blurred or noisy. Scenes from a sunny street to the Milky Way earn one to three stars, a scene of the week waits for you, and you can share a good shot.
ACADEMY: A COURSE THAT IS FUN
• 26 short lessons in three levels, from the mode dial to the zone plate
• Practice right in the tool, a quiz and a photo task for your real camera
• Warm-up: up to three questions from the lessons that are starting to fade
• A level test when you already know the basics, and a skill map that shows how far you have come
• Circle of Confusion: the 25 most common photography myths and what is really true
• A glossary and a medal for every level
INTO THE FIELD AND UNDER THE STARS
• A rotary dial with gentle haptics, made for one thumb
• Night mode in red on black only, with extra-low brightness to protect your night vision
• Beginner, Advanced, Expert: the app grows with you and shows as much as you need right now
• Myth or fact? on Home and as a home-screen widget
• A camera bag with 12 badges for exploring
NO ADS, NO ACCOUNT
No ads, no account and no sign-in. Your phone does all the maths, offline.
Available in 10 languages: English, Czech, German, Spanish, French, Italian, Brazilian Portuguese, Polish, Japanese and Korean. Works on phones and tablets.
