Lasers, searchlights, car headlights and other light sources of sufficient power can form a column of light in a dusty or foggy atmosphere, various patterns on low clouds, fog or haze. Also, the rays can highlight parts of the cloud, objects or birds, giving them bizarre shapes.

Searchlights can shine with one beam, several. They can be stationary, move, and also form spinning carousels on the clouds, which can change shape and color.

It often seems that the light source is located at the point where the beam hits the cloud, and not vice versa.

Solid precipitation in the form of fine ice crystals floating in the air, resulting in cold weather (air temperature below -10...-15°). Day sparkle in the light of the sun, at night in the moonlight or by the light of lanterns. Often ice needles form at night beautiful glowing "pillars", coming from the lanterns up in the sky.
Occur most often during clear or cloudy the sky, sometimes fall from cirrostratus or Cirrus clouds.

When the objects are out of focus, their silhouettes blurred and poorly recognizable. They can look like dark or colored translucent stain. This is often the cobwebs, spiders, insects in front of the camera.

One of the most frequent types of halo, a visual phenomenon, an optical effect which is a vertical band of light stretching from the sun during sunset or sunrise.
