Shooting tethered (when your camera is connected to a computer with a USB cable) is great because you see photos immediately on a big screen. However, the tether cable can often get unplugged during a shoot. There are JerkStopper tools you can buy to securely attach a USB tether cable to your camera to prevent dislodging. However, I found a very easy DIY and free way to securing USB tether cable to a camera, using an item that is in every household - plastic twist ties.
