Menu screens from Canon and Nikon DSLRs show the best image-quality settings to use.

>>Smooth Like Silk. One of the last settings to determine is shutter speed. Set your desired shutter speed based on the effect you want. The longer the exposure, the smoother the motion of the action in your scene. By dragging your shutter (shutter open longer), you're able to hide exposure changes, and as a result, remove some of the flicker that would have been present otherwise. Usually, I wouldn't recommend a shutter speed faster than 1⁄100 sec., as you'll start to see more flicker from changes in light within your frame.
Most Canon DSLRs don't have internal intervalometers, but Canon makes the TC-80N3, which works with most of their cameras.
Time Is Everything
Zero out the intervalometer in all modes and set the delay mode to the desired time. Some intervalometers require you to set your time between frames using the interval setting. If you're in Bulb mode, set the "long" option to the desired exposure time. When deciding on what interval to use, make sure the time between photos is at least the amount of time it takes to both expose and buffer the given image.
|The Lens-Twist Method|
|A stopped-down lens will always cause a certain amount of flicker because between frames the aperture opens, then stops down again, just before the exposure is made. It's impossible for the aperture blades to close in exactly the same way in every exposure. The "lens-twist method" locks the aperture blades. To do it, establish the aperture you want to use and set it on the camera or lens. Press the depth-of-field preview to stop down the lens to that aperture and simultaneously depress the lens release button. While holding the DOF preview button, twist the lens slightly. Your camera will lose contact with the lens and the blades will remain locked in the stopped-down position. You'll lose the lens metadata information in the exposures, but that's a small price to pay.|
