TISHITU Time Lapse Day Night in two minute

Tishitu explains Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, then played back at 30 frames per second. The result is an apparent 30-times speed increase. Time-lapse photography can be considered the opposite of high speed photography or slow motion. Processes that would normally appear subtle to the human eye, e.g. the motion of the sun and stars in the sky, become very pronounced. Time-lapse is the extreme version of the cinematography technique of undercranking, and can be confused with stop motion animation. In time-lapse videography , the camera records images at a specific slow interval such as one frame every thirty seconds (1/30 frame/s). The shutter will be open for some portion of that time. In short exposure time-lapse the film is exposed to light for a normal exposure time over an abnormal frame interval. For example, the camera will be set up to expose a frame for 1/50th of a second every 30 seconds. Such a setup will create the effect of an extremely tight shutter angle giving the resulting film a stop-animation or claymation quality. In long exposure time-lapse, the exposure time will approximate the effects of a normal shutter angle. Normally, this means the exposure time should be half of the frame interval. Thus a 30‑second frame interval should be accompanied by a 15‑second exposure time to simulate a normal shutter. The resulting film will appear smooth. The exposure time can be calculated based on the desired shutter angle effect and the frame interval with the equation: TISHITU ISO: 9001-2008 RESEARCH AND CONSULTANCY CELL OF INDUSTRIAL APPLICATION A Joint Accreditation System of Australia and New Zealand Copyright © All Rights Reserved www.tishitu.org Reg No.08122629691/SSI Accreditation No. M3111204IN contact , [email protected] ~-~~-~~~-~~-~ Please watch: "Lifi Communication by Arduino UNO Download Project"    • Lifi Communication by Arduino UNO Download...   ~-~~-~~~-~~-~
