Additionally, when you are shooting non-moving subjects, you can trip your shutter using the self-timer (My Canon cameras have a 10 second self timer choice which is great for this. I don't know about the Nkon cameras).
Some Canon cameras (mainly the Rebels and the 7D) have a built-in Infra-red release which can be used with a IR trigger.
The Canon cameras which do not have the built-in IR release can be tripped remotely with a two part release. One part plugs into the socket for the corded release and contains a receiver which trips the camera when activated by a corresponding IR controller.
However even the cameras which contain a built-in IR release can benefit from using the two part release system because the two part release can be tripped from either behind the camera or from the front of the camera; while the built-in IR release can only be tripped from in front of the camera. Obviously tripping the camera from in front of the camera is great for taking your own picture and anytime you can have the trigger pointing towards the front of the camera. Tripping from the rear is better for macro shots and night shooting and anytime you
There are also corded release triggers which are physically connected to the camera by an electric connection usually about several feet or so long. The corded release can be operated from in front or behind the camera as long as you are within the length of the cord from the camera. Additionally, when triggering from the front of the camera, you need to make sure that the cord is not in your frame.
BTW: I have had absolutely no problems using third party remote releases available on eBay.
