In the olden days, even expensive projectors were Jessica Simpson-dim, which meant room lights at zero and blinding spotlights on the presenter. Concert-style lighting, professional performers, expensively-shot video, maybe even dancing bears. Today’s projectors are bright enough to work under most lighting conditions. I’m in a very dark place right now. Which makes me sound like some kind of moody, tortured Christian Bale Batman character, and nothing could be further from the truth.
