Of course it does, it has full manual control (M), but may I suggest first trying "shutter priority" (Tv). This mode lets you set shutter speed up to 15 seconds, but it automatically sets the aperture to match the shutter speed that you set. Merely turn the mode dial to Tv, then use the right/left buttons to select the shutter speed.
Now before pressing the shutter button, may I also suggest that you use the camera's shutter delay timer to take the picture (this will eliminate any shake from you pressing the button). Just press the function button to bring up the menu. then find the timer setting (try 2 seconds).
