Open Skies tells you exactly when the light and weather will be right for the photo you want to make — hour by hour, seven days ahead, for anywhere in the world.

Instead of a generic weather app, Open Skies scores every hour from 0 to 100 for seven kinds of photography, weighing cloud cover, wind and gusts, precipitation, visibility, humidity, sun angle and moon conditions.

SEVEN PHOTOGRAPHY STYLES Landscape, Portrait, Street, Wildlife, Astrophotography, Macro, and Fog & Mist. Each one reads the same weather differently — heavy overcast is a softbox for portraits but flat for landscapes, and dead-calm air is everything for macro.

LIGHT THAT ACTUALLY MATTERS Golden hour, blue hour and astronomical darkness are calculated from the real position of the sun at your exact coordinates, not a fixed offset from sunset.

BUILT FOR ASTROPHOTOGRAPHY Open Skies models the moon the way astrophotographers actually think about it: not just the phase, but how high the moon sits in the sky. A bright moon overhead floods everything, while the same moon near the horizon barely dims the stars and gently lights your foreground. A moon below the horizon means the darkest sky you can get. Dark-sky (Bortle) ratings are built in.

FIND WHERE TO SHOOT • Best Conditions Nearby — scan a 50-mile radius for the clearest skies in the next few hours. • Locations — a map of photogenic places around you: viewpoints, parks, lakes and coastline, landmarks and public art. Every pin is coloured by how good conditions are right now, red through green, so the best place to be is obvious at a glance. • Severe-weather alerts — active National Weather Service warnings for your area (US).

KNOW YOUR SETTINGS Tap any hour for a suggested aperture, shutter speed, ISO and white balance, tailored to the conditions and the style you picked — plus the tips that matter in the moment, on wind, dew, the 500 rule and more.

A PHOTOGRAPHY GUIDE WORTH READING Exposure, composition, lighting, editing and colour grading, explained with diagrams instead of jargon. Per-style guides cover camera handling, light, composition and Lightroom for each of the seven styles. A lens buying guide covers zoom versus prime, what a faster aperture really costs in weight and money, and the point where price stops buying image quality.
