Document Summary
The 1101: intro to the practice of theatre - backstage. Creative field of stagecraft and can have many functions in theatre: to create an illusion or an effect, establish a location, or tell the story. Projections for viewing videos in a large rom or auditorium, for example, will require a higher resolution than projectors used for powerpoint presentations in a classroom. A resolution of 800 x 600 dpi (dots per square inch) is generally adequate for basic powerpoint presentations in an office or conference room. 1024 x 768 or higher allows for more detail and 1280 x 1024 for an even higher quality image. Brightness and contrast are important elements of image quality. Lumens range from 500 to 1,000 for small, dark rooms to more than 2,000 lumens for large, brightly lit rooms. Additionally, the larger your screen size, the more brightness you will need. In academic hall, our projectors are 6000 lumens.
