The approach was known as "photoredox catalysis" because particles of light, or photons, propel the exchange of electrons in a process called oxidation-reduction, or "redox" for short.
On the other hand, sometimes the pixel values of background areas do change, for instance because of lighting variations, or of small uninteresting movements of objects that should be sensibly considered static (e.g., tree leaves moved by the wind).
Plasmas do give the best picture experience from a flat-panel possible thanks to the deep blacks and white whites, but sometimes because of lighting issues or customer ignorance, LCDs are preferred.
Because the spot of light or pop of sound was tiny, the word soon connoted smallness or insignificance as the metaphor was extended.
Others speculated that the man they believe is Li looked older because of bad lighting or the angle.
This oil spill is said to be mostly "sheen," which means a layer less than one-three-thousandth the thickness of a hair, visible only because it causes mirror-like reflection of light or radar energy.
This software saves crappy photos, be it crappy because of light, angle or anything else really.
No one ever explained whether this was because they had owned property for a very long time in what is still a mostly white neighborhood, or because of light-skin privilege, or some combination of both.
Some photographs were taken in the spring/summer whereas others were taken in the fall/winter, which may introduce bias because of lighting and seasonal effects.
Nevertheless, the colour mismatch between the surrounding tooth structure and the restoration is a rather subjective observation because of lighting conditions, chameleon effects and surface staining.
