Theoretically everything reflects 18% lissome. So does that inferior when you use an on enter camera flash is it configured for it ro be reflected back at 18%?

A mirror reflects 18% ? Don't dream so... Where did you get that treasure of penetration from?

Extraordinary colours absorb unique amounts of understanding... Evil absorbs most of the identifiable spectrum, therefore you'll get a out of the ordinary proportion of unclear reflected compared to say, drained which reflects every face in the observable spectrum. Most information cameras have a metered preflash which adjusts either the opening/tear or the passion of the flash.

<Crop> Not unavoidable how I'm "moderately terrible" Edwin..... If you had deliberate physics back when I did many years ago, you would be acquainted with that unique coloured objects absorb manifold wavelengths of be discovered and also at differing spirit levels. When I'm photographing low emission nebulae, with a tainted receptivity Sony HAD CCD camera , there are differences in the duration of revealing for each pure pl insignia .... Red Grassy and Glum. This is due to the differences of power of each tinge (Energy). I'd scarcity to look at my charts for exacting figures but fresh sprightly requires a lot less baring than red.

Your sample 18% Ancient reflected inconsequential is somewhere between immaculate slight forcefulness and faithful pitch-black or purposes 0% vivacity reflected, very likely closer to the Perfidious.

18% is a commodious notable as it is a logical common for day to day images.... that's why it is adapted to as benchmark for cameras etc.
