Re: comments by someMidTowner & TStephens...........
There appears to be some difference of opinion over the meaning of "time lapse" photography.
1- Time lapse usually refers to motion pictures in which the shutter is released intermittently with a time delay between each exposure.
The time delay can vary from seconds to minutes or longer.
When the motion picture film (or video) is viewed at normal speed, time will appear to be speeded-up........e,g, a flower will grow & blossom in seconds rather than days.
2- A photo taken with the shutter left open for a long interval is known as a "time exposure."
Time exposures of traffic at night for example, will show light streaks as cars move within the image during the single, long exposure..
A time exposure is usually displayed as a single still image.
