![]() Brightness constancy is one of the perceptual constancies. For example, a piece of white paper has a similar brightness in daylight as it does at dusk, even though the energy it reflects may be quite different. We can also help you choose the best laptop screen for your needs. the tendency to perceive a familiar object as having the same brightness under different conditions of illumination. Looking for a new TV and not sure how to choose? Learn what to look for to pick the best option for your home theater. The most important thing is just knowing what a low, medium, and high nit number looks like for a given device so you can make an informed decision. Resolution, contrast ratios, black levels, sRGB color, and other factors also affect your screen quality, and as long as you’re not on the far low end of the nit range, you’re probably fine. Nits are important but shouldn’t be the one deciding factor in your screen choice unless you specifically need something above a certain level of brightness for HDR or outdoor use. Higher-end HDRs can be 2000 nits or more. HDR TV works best with high nit counts and generally requires a minimum of 500, with a lot of models aiming for at least 700. Older TVs probably fall in the ~100-nit range, but most modern non-HDR displays fall in the 200 to 500 range. However, nit is often used in place of candela to avoid simply sound liking you’re measuring brightness based on candles, even though you technically are. It stems from the Latin word “nitere,” which means to shine. For one color of specific hue the perception of brightness is also more intense, if we increase saturation. Brightness is not a color property, if used 'correctly'. This is probably why brightness and lightness are often mixed up. It’s important to know that nits brightness isn’t an official measurement. Brightness is an attribute of our perception which is mainly influenced by a colors lightness. You’re probably more used to hearing lumens versus nits, which is probably what you’re asking yourself – “what is a nit” – when you come across the measurement. ![]() More nits = more candles per square meter = brighter display.Nit = the light from 1 candle per square meter.Candela = about the light from 1 candle. ![]() If you skipped down to the end of that hoping to find the super-simple summary, here it is: That’s why using a phone during a movie is so taboo: with at least ten times the candela per square meter than the screen, it’s basically a magnesium flare in a dark theater. SI base units, including meter (distance), kilogram (mass), and candela (light)Ī theater projector is probably emitting more total light (measured in lumens) than any smartphone, but the phone packs more light into a smaller space.
