Working without a tripod is always recommended, working without a tripod in low light is vital … how about doing a long exposure without a tripod? The following image was taken at Niagara Falls about 30 minutes after sunset and it was a 20 second long exposure of Niagara Falls at Night.

Thanks to a table, 2 phone directories and a small box to stabalise under the lens (so that the lens didn’t drop and face downwards). I focused manually, turned off AutoFocus and MirrorLockup, used a cable release and prayed. The resultant shot is shown below.

Its a nice shot and I like the colour on the waterfalls which is a result of coloured lights placed near the falls.
I had never taken a photo of a waterfall at night but these powerful lights on the American Falls really helped.
