When using a tripod, one of the most important steps to take is to ensure that it's properly secured. To do this, make sure all three legs are firmly planted on the ground and that each leg is locked into position by tightening the knobs or adjusting screws. Additionally, if you're shooting in windy conditions, use sandbags or weights at the base of your tripod to help keep it stable. Finally, check regularly throughout your shoot to make sure none of the legs have shifted and that everything remains secure and safe.
