The cover of Learn Photography with Chobial, a free photography book

The chapter on shutter speed starts with a horse. It's Eadweard Muybridge's The Horse in Motion, a set of photos of a trotting horse. Every chapter in this book opens like that, with a photo by a well-known photographer and a look at what the photo shows.

I'm Masnun, and I make Chobial, a film camera and photo editor app. I wrote Learn Photography with Chobial so people with Chobial can learn photography with the camera they already carry. The cover says the book goes "from your first photo to a whole roll." Along the way, it covers light, composition, exposure, phone cameras, film looks and editing, one step at a time.

What the book teaches

The book starts from zero. The first idea comes in chapter 0. Every control in the book changes one of three things. It changes how much light comes in, how long the light comes in for, or how the light is turned into colors.

After that, you learn composition, light, exposure, focus and color. Then the book covers phone cameras, film looks and editing. The fourth part is about taking photos of real life: people, streets, food, pets, the weather and buildings. In the last chapter, you shoot a whole roll as a final project.

Every chapter uses Chobial on iPhone as the camera. Where Android works differently, a short "On Android" note says how. On a phone, the aperture can't be changed, so the book shows other ways to get a soft background. You can get close, or use 2× or the telephoto lens.

How each chapter works

Each chapter opens with a public-domain photo. Public domain means anyone may share and print the photo, so these photos can be in a free book. You'll see work by Dorothea Lange, Gordon Parks, Ansel Adams, Alfred Stieglitz, Lewis Hine, Julia Margaret Cameron, Eugène Atget and Muybridge. Chapter 6, on viewpoint, pattern and moment, opens with Stieglitz's The Steerage from 1907. Chapter 0 opens with Ben Shahn's 1938 photo of a traveling photographer's plain wooden box camera in Columbus, Ohio.

After the photo, most chapters have the same parts:

  • The idea, in plain words.
  • In Chobial: numbered steps with screenshots of the app.
  • See it: the same scene done two ways, side by side.
  • Common mistake: the trap beginners fall into, and how to fix it.
  • Try it: one exercise to shoot in the app.

The book has 189 pictures in all, counting photos and app screenshots.

Written in plain English

I wrote the book for beginners and for people whose first language isn't English. The sentences are short and the words are common. Every photo word is explained the first time it's used, and the glossary at the back collects them all. The book is in English only.

The pages are A5 size. That's a small book page, about 15 × 21 cm.

The pages at the back for looking things up

  • A glossary of 258 photo terms. Each term shows the chapter that explains it.
  • "My photo is…" helps you find what went wrong and how to fix it. It covers photos that are too dark, too bright, blurry, flat, orange, blue or noisy. It also covers crooked photos, skies gone white, and colors that look fake or overedited.
  • Cheat sheets: shutter speed by subject, white balance by light, the exposure triangle on one page, and a film picker by light.
  • Starting settings for each situation.
  • A 30-day challenge: one exercise a day from the chapters' "Try it" parts, 10 to 30 minutes each. Day 1 is ten photos on Auto. It's fine to skip a day.
  • A map of Chobial's screens.

About Chobial

Chobial is a film camera and photo editor for iPhone, iPad and Android. The Android app is in a closed beta on Google Play, and the Android beta page has the details. The camera shows the film look live in the viewfinder and saves RAW by default. A RAW file is the full data from the camera's sensor, before any color style is added. Every photo keeps its original, so you can develop it again later with another film.

Chobial has 46 films built in, and 22 of them are free. You can see them all on the films page. It's free to shoot, develop and make films. Pro is a one-time purchase or a subscription.
