DSLR cameras offer choice of shutter release modes which controls the way you want your shutter release button to behave. By default when you press the shutter button, the camera takes a picture, you press it again and it takes another one. But there are other options available which you can choose depending on your requirement.
S – Single Shoot Mode: It is the default mode. When you press the shutter it will take single picture. This is the normal photography mode.
CL – Continuous Low: It’s a burst mode but at a low speed. The camera will continuously take pictures till the time the shutter button is pressed at a user defined speed. This mode is useful when the subject is moving but at a low speed.
CH – Continuous High: It’s a high speed burst mode. The camera will continuously take pictures at the maximum speed capacity of the camera till the time the shutter button is pressed. This move is useful for sports or any fast action.
Q – Quiet Mode: This mode allows you to take picture quietly. It does not eliminate the shutter/mirror sound completely but its reduces it to a great extent. In addition to delaying the mirror sound it also silences the beep of the autofocus. This mode is quite helpful when you are shooting in a location when you want to maintain silence.
QC (Quiet Continuous): This mode is quite similar to the Quiet Mode with a continuous shooting mode.
Self Timer: This allows you to program an interval between pressing the shutter and taking the picture. The delay is user defined. This mode is useful when you want yourself to be in the picture or move away from the camera when it takes the picture.
Remote: This allows you to take a picture with an external wireless remote. It can be helpful just as the self timer shooting mode.
Mup (Mirror Up): If slightest camera movement is also critical for the picture, then this is the best mode to choose. Since you would want absolutely still camera, you will use a cable release in this mode. You have to press the shutter release in the remote twice, once to lock the mirror and second for the exposure. This is a very useful mode for creating ultra sharp images when the camera is on a tripod and using a slow shutter speed.
