Tripod Heads and Methods of Creating Drag
a. Friction Head – develops drag by the friction of two metal-surfaced or fabric-surfaced plates
b. Spring Head – creates drag through a set of springs
c. Fluid Head – drag created by the movement of a thick fluid from one chamber to another
Pan (Horizontal/Table Plane)
The camera motion commonly known as panning occurs in the horizontal/table plane. This action moves sideward, while maintaining consistent level. Think of the eyes tracing the horizon as the head rotates to the side (like nodding the head “no”). As the pan occurs, the vertical composition of vision changes as objects slide right or left. The pan emphasizes horizontal motion, but requires an eye for vertical composition.
Traveling Side Phrase
“When panning with the camera, place your feet in a comfortable position at the finish of the pan. Then twist your body into the starting position. This unwinding effect allows your body to relax as it approaches the end of the pan, instead of building tension and the shakes that go with such tension. This same technique works somewhat the same in lengthy tilt. Position your body in a comfortable position at the end of the tilt, not at the beginning.”

Tilt (Sagittal/Wheel Plane)
The camera motion commonly known as tilting occurs in the sagittal/wheel plane. This action moves upward and downward, while maintaining consistent facing (like nodding the head “yes”). Look down to your feet and extend the cervical spine as the eyes arc through forward/diagonal/low, forward/middle, forward/diagonal/high, place/high. As the tilt occurs, the horizontal composition of vision changes as objects in sight rise or descend. The tilt emphasizes vertical motion, but requires an eye for horizontal composition.

Rotate (Frontal/Door Plane)
Camera motion that rotates is slightly less common than panning and tilting. This action involves clockwise or counter-clockwise rotation while remaining in the frontal/door plane. This one’s a bit harder to illustrate on the human body, but imagine an axis that passes from front to back through the space between your eyes. Now, try evenly rotating the eyes around that point. Maybe this is why it is less common! A rotating shot exhibits a circular shift of both the horizontal and vertical composition and results in disorientation to gravity. A rotating action that moves back and forth would cause a see-saw effect on the horizon. This is a great action to use if you want to upset the stomachs of your audience!
