Gaff tape refers to a specific type of tape carried by gaffers and grips that works best for applying to lights, rigging equipment, and camera gear. It’s very durable, but easily removable, as it doesn’t stick so strongly to walls or equipment that removing it will damage paint or leave thick tape residue.
Gels are colored plastic filters that are used to cover the front of a light. In the same way, a polarizer or colored filter can change the colors your camera picks up, gels are used to change the color of the lights themselves.
For example, you might use a blue gel to make a light cooler in temperature or use a red gel to create a warmer temperature light.
