Light...

Long exposure photography takes patience and especially timing. The speed of the shutter determines the amount of light let into the camera's eye which will appear in the photo. The photos below resulted from practicing and experimenting around with a 5-watt torchlight in the dark room of knowledge a.k.a my home library. ;)

If you are curious, these shots were taken using TV mode (shutter speed priority), a tripod, a two-second delay or timer and a torchlight. :)
