Is Screen Luminance Level Important?
To understand why screen luminance is important, we need to understand human vision. During the daylight, our vision is fully functional so colors appear brighter, and we see with maximum sharpness. In dim light, colors appear desaturated, and we may have problems seeing detail. At intermediate levels of light, we may see color and detail, but not with the same vividness. Theatre screens fall into this intermediate level, where a small increase in luminance can make a big improvement in color perception and visual acuity. Back To Top ^ Is Brighter Better? To demonstrate the effect of screen luminance on image quality, we made two identical prints, color timed at the laboratory screening room standard of 16 fL. We included a variety of scenes having highlights, shadows, fleshtones, bright and pastel colors, and good sharpness. The matched prints were projected side-by-side on identical projectors, one at 12 footlamberts, and the other at 22 footlamberts. The print projected at 22 fL had
