Help
Shutter Speed is a planning companion for photographers and filmmakers. It helps you decide when and where to shoot, and what to expect once you are there: light, moon, sky, weather, and tides for your location.
How the app is organized
Tools are grouped into sections on the Home screen and in the bottom navigation bar. Right now these are available:
- Planning:Location Planner, Shoot Forecast, Compass
- Conditions:Light Conditions, Weather, Tides, Barometer, Lens Fog Risk
- Astrophotography:Moon Phase, Star Trails, Eclipses, Milky Way Visibility, Aurora Visibility, Comet Tracker
Some tools are limited to certain devices. Compass and Barometer work on iPhone only. Everything else works on every platform the app runs on.
Each tool has its own page with steps, how to read the results, and tips. Inside the app, tap the (i) icon on a card for a short explanation of that card, or open Settings, then About & Support, then Quick Reference for a summary of what each tool does.
Getting started
- Set a location. Most tools depend on where you are. Use the Location picker at the top of a tool to choose Current Location or a saved location, or add one. You can also manage this in Settings. Until a location is set, location-based results show a dash or ask you to set one.
- Open a tool from Home, or use the search icon in the toolbar to find one by name.
- Read the result, and tap the (i) icon if a term is unfamiliar.
An account is optional
You do not need an account to use the tools, with one exception: Location Planner asks you to sign in so your saved pins can be stored and synced. Account options (email, password, two-factor authentication, deleting your account) are under Settings then Account.
Settings worth knowing
- Units: switch between Metric and Imperial. This affects distances, temperatures, and similar values. Focal length always stays in millimeters. Pressure has its own unit setting (hPa, inHg, or mmHg).
- Appearance: follow your device, or choose Light, Dark, or Mono. Icon Style switches between color icons, black and white icons, or no icons.
- Home Layout: All Tools or Custom View.
- Backup & Restore: under Your Data.
