For you who do not know what timelapse is, it is a series of still photographs taken at regular intervals then joined as a video to show a view that has been "speeded" up.
Have a look there at this one.
This will give you an idea.
This has been taken using my own made panning head to revolve the camera at the same time as taking the photographs.
This video contains over 1200 photographs taken over a two hour time period.
You MUST ensure you have a good camera battery !
If you would like details of the Panning Head, or even wish me to make you one then please mail me and I will try my best to help you.
The important part is getting the speed slow enough to give a smooth rotate.
