How do I set up and use the self-timer feature on the Canon 70D camera?

To set up and use the self-timer feature on the Canon 70D camera, first, locate the self-timer button on the camera. Press the button and use the dial to select the desired delay time (usually 2, 10, or custom seconds). After setting the delay time, compose your shot and press the shutter button. The camera will then count down before taking the picture.
