Time Lapse
Time-lapse photography shows progress or change over any period of time in a series of photographs and blended together to create an illusion of time passing quickly.
The time between each photograph, known as the 'interval', is different for different types of project and can range from 0.5 of a second up to 10 minutes intervals.
The cameras can set up at ground level or 8m up on a trailer mast.
