Plan your next photo adventure
Shutter Speed plans your shoot and tells you what the sky and weather will do.
Shutter Speed is a planning toolkit for photographers, videographers, and astrophotographers. Save and revisit shoot locations, get a quick read on whether tonight is worth shooting from sun, moon, eclipse, meteor shower, and aurora highlights, and check live weather, tides, and lens-fogging risk before you leave. Built so the guesswork happens at your desk, not on set.

- Light ConditionsGolden Hour, Blue Hour, Twilight, sun direction, day length, and solar noon for your location.
- TidesToday's tide times and heights from real NOAA station data where available, or a rough offline estimate elsewhere.
- Lens Fog RiskEstimates whether current humidity and temperature carry meaningful lens/gear fogging risk, based on live dew-point data for your location.
- Fog ForecastPredicts upcoming atmospheric fog for your location: hourly for the next 48 hours, then daily likelihood for a few days beyond, from live provider forecast data.
Astrophotography

- Star TrailsLongest exposure before stars visibly trail on a fixed tripod, by the quick 500 Rule or the precise NPF Rule.
- Milky Way VisibilityForecast moon-free nights when the Milky Way core is visible above the horizon during astronomical dark.
- Meteors & CometsSee which major annual meteor showers are active and whether their radiant is visible tonight from your location, plus upcoming comet apparitions with expected peak brightness.
- EclipsesSee upcoming lunar and solar eclipses, and whether they’ll be visible from your location.
- Aurora VisibilityEstimate the Kp index needed to see aurora from your location, and tonight’s dark-sky window.
