Mysterious Rays of Light Around the World – EXPLAINED
A strange wave of sightings of ray or a beam of light is showing up in recent days in different parts of the world. A facebook page ufoonly has released some amazing images taken by several eyewitnesses. The phenomenon has been reported in Genoa Italy, BCS Florida USA and Mexico. This beam of light is reminiscent of the beam that is present on some famous pyramids in the world a few years ago.
Website Megabunk.org thinks there is another explanation – something called rolling shutter. A “rolling shutter” means that the image is recorded one row (or column in portrait orientation) at a time, and not simultaneously.
Rolling shutter is a method of image capture in which a still picture or each frame of a video is captured not by taking a snapshot of the entire scene at single instant in time but rather by scanning across the scene rapidly, either vertically or horizontally. In other words, not all parts of the image of the scene are recorded at exactly the same instant. (Though, during playback, the entire image of the scene is displayed at once, as if it represents a single instant in time.) This produces predictable distortions of fast-moving objects or rapid flashes of light. This is in contrast with “global shutter” in which the entire frame is captured at the same instant.
The “Rolling Shutter” can be either mechanical or electronic. The advantage of this method is that the image sensor can continue to gather photons during the acquisition process, thus effectively increasing sensitivity. It is found on many digital still and video cameras using CMOS sensors. The effect is most noticeable when imaging extreme conditions of motion or the fast flashing of light. While some CMOS sensors use a global shutter, the majority found in the consumer market utilize a rolling shutter.
CCDs (charge-coupled devices) are alternatives to CMOS sensors, which are generally more sensitive and more expensive. CCD-based cameras often use global shutters, which take a snapshot representing a single instant in time and therefore do not suffer from the motion artifacts caused by rolling shutters.
