Two types of pan heads commonly found on photographic tripods?

• A. Ball and Socket
• B. Rigid and Flexible
• C. Friction and Fluid
• D. Magnetic and Hydraulic

Answer: (C)

Pan heads are designed to control and smooth the motion when you pan left/right and tilt up/down. The two most common types you’ll encounter are friction heads and fluid heads. A friction head uses adjustable resistance on the pan and tilt axes, so you set how easily the head moves and how firmly it holds a position once you stop pushing. This makes it reliable and affordable for still photography where precise lock-in is important. A fluid head, on the other hand, uses damped fluid chambers to create a smooth, controllable motion, which is especially valued in video work where gradual, cinematic movement matters. The other terms listed don’t reflect the typical, widely used categories for pan-head designs—ball-and-socket describes a different joint style, and the others aren’t standard classifications for pan-head mechanisms.
