As a general rule in photography when you’re handling your camera you should aim for a shutter speed that’s as fast as the lens’ focal point. It’s a bit complicated for most DSLR because of the crop factor.
For example you have a 18-55mm kit lens (which most DSLRs have) and you have an effective focal length of around 28-90mm, if you use the reciprocal law you will need to adjust your shutter speed to 1/28 sec to 1/90 sec depending if you’re using a wide angle or telephoto zoom range.
When you’re shooting low light the latest generations of DSLRs have image stabilization or vibration reduction, this gives you three or four stops to play with before camera shake become a visible problem.
Another tip is to invest on a good solid camera tripod for sharper photos, also a wireless remote helps eliminate the shake or noise.
If you don’t have a tripod or wireless remote trigger another ingenious tip is to prop your camera on a solid surface and use the timer to take a photo, that way you don’t ‘shake’ the camera when you press the shutter.
