Avoid too many head-high shots - work from different angles and points of view.
Do NOT use the zoom - unless absolutely necessary
Do not pan (swing camera horizontally) on static images unless there is no alternative
Do not overuse one shot - shoot long shot, medium, close-up
Whenever possible use a tripod - leave the camera on the tripod
Never shoot a scene longer than 20 seconds unless there is something vital happening at the time
Look at the viewfinder so that - you see, you perceive,you observe everything that is going on. Viewers have eyes like hawks!
