Step 1: Understand How the Lens Works.
A lens (derived from the Latin word for "lentil") is a transparent piece of glass with one or two curved surfaces.
A lens uses refraction to bend rays of light as they pass through the lens.
This refraction is what causes images to appear larger or smaller than they truly are. -
Step 2: Consider Context.
What is the environment like? It is broad and spacious, or close quarters? Will you be able to position the projector directly in front of the screen, or will you need to put it at an angle? , The more lenses you choose, the greater your investment.
Can you rent a lens to try it out? How often will you need a particular kind of lens? What kind of maintenance, upkeep and storage are required for additional lenses? -
Step 3: Evaluate Cost.
