Initial data
Very often on pictures with many different photographers, and beginners and professionals can find strange photoactivity. The more gray hairs in the temples relieves, the less each oddity it seems. There are however, phenomena that are more familiar to professional UFO researchers than even a fairly experienced team. A similar effect was on the Foty night city made in the city of Cherven (Minsk region), in 2006.

Two months ago photographed by the digital camera city at night from the balcony. Nothing unusual was seen. Found after pouring the images to a computer. The picture shows two objects of "parachutists."
Camera Canon PowerShot A610. Shooting from a tripod. Shutter speed 15 seconds.
Three bright object in the background are street lamps. But "jumpers" is a UFO or a glare on the lenses of the camera lens?
Full-sized original from the camera without processing or can send on request.

My diagnosis is a classic example of the effect of catadioptric.
Catadioptric is the scientific term for specks from optics, photo or film negative and prints. Synonyms: lens flares, Lucarelli Mikirova (named after the scientist who first described the effect in Russian in the newspaper "Komsomolskaya Pravda" on 8 January 1961).
Glare result from bright light sources, located at the side of the lens; the axis of the image is always aimed at them. Adjusting the angle between the optical axis of the lens and the direction of the light source, it is possible to obtain a variety of shapes. These images it is easy to see directly in the mirror the viewfinder. That they turned out well in the picture, only need relatively large exposure. If the camera is rotating around the optical axis, the image without changing its shape, will move.
Arguments:
- being on the edge of the photograph strong light sources.
- "jumpers" are a body of revolution.
- long time exposure.
- the Central axis of these "parachutists" as time is aimed at bright light sources.

Re-reflections in lens lenses from a strong light source
The lens consists of a set of lenses (in some lenses - of mirrors), designed for mutual compensation of aberrations and assembled into a single system.
From the contour light (bright light sources behind the subject or next to it), caught in the frame or located outside the frame, parasitic reflections from the internal elements of the lens are formed, called glare (or in slang "hares").
