UFO. Germany

Often it's a small point on the photos, like hovering metal ball. At least - this is quite a big blur. Color, brightness and the presence of a highlight depends on the color of the reflected light source, background shooting and drop form.

Shape, color and density of pollution may vary depending on the source of the contamination and its nature. This can be as a desired pattern on the glass, and random.

Most often this artifact is called skayfish if the lens gets a passing bird or insect. It is based on the discrepancy between the speed of the video and the frequency of the flapping of insect wings. Essentially, each video drops a few strokes of the wings of an insect, which when viewed looks like "arrow", provided with long protuberances. The motion of the insect by its translucent body seems to "boom" and vibration of the wings give the appearance of bumps.

In many cities (especially European) are widely distributed street lights, weighing on an extension wire. Sometimes, when photographing a landscape, a lantern in the sky can be mistaken for a UFO if the wires will not be visible (e.g. under a certain angle).

It happens that the author deliberately blurs the wires.

Sometimes these lights are used for an intentional imitation of a UFO due to osobennostei design.

Sometimes a UFO can be taken lights caught in the frame part, or as a contrast object against a plain background when shooting at night.
