Time-Lapse photography seems harder than it really is. All that you have
to do to produce a time-lapse photograph is keep the camera's shutter
open for an extended amount of time while the subject has a chance to
move. With a manual camera, the shutter speed should be set to B (Bulb).
On this setting, you can simply hold the shutter open as long as you want
to while taking the picture. The key is to steady the camera. I suggest
using a tripod.
In bright sunlight, holding the shutter open for more than a second or
two (even with a narrow aperture)
might overexpose your image. Some of the best time lapse photographs are
taken in dusk or ver low light situations. The subject that moves is then
represented as a streak while the background has a chance to burn itself
on the film over the duration of a few seconds.
Some
photographers have even taken pictures over the course of an hour or more.
The image to the left of the night sky shows the rotation of the Earth
in relation to the stars. The camera and the shrubs at the bottom of the
image were both on the surface of the Earth, so the shrubs remain in perfect
focus, while the stars seem to streak due to the rotation of the Earth.
This exposure was roughly 1.5 to 2 hours if not more.
