Light and colour in the open air

An atmospheric optics simulator

Drag the view to look around; scroll, pinch or use + and − to zoom; double-click to reset the view. Photo look renders like a processed camera image (cooler white balance, more saturation and contrast), which helps when comparing with photographs. Compare photo loads a picture from your device over the simulation, with opacity and wipe controls, so you can check a scene against a real photograph; the photo never leaves your device. Keys [ and ] step through phenomena; Tour steps through them automatically. In mirage scenes, drag up and down to move the view. The address bar keeps the current phenomenon, settings and view, so it can be bookmarked or shared.
