Subject field(s)
  • Photography
  • Cinematography
  • Optics
CONT

When you take a picture at the seashore or in the highlands or of a distant view, the photograph is on the whole rendered indistinct with a bluish veil added to the entire picture under the influence of ultraviolet rays, which are invisible to the naked eye. In such cases, the proper choice is the UV filter, which is colorless and cuts off only the ultraviolet rays and does not necessitate an increase of exposure.

CONT

Filtre UV. Ce filtre incolore élimine les ultraviolets, atténue voile atmosphérique et dominante bleue et améliore légèrement le rendu des verts. Il est conseillé de l'utiliser à la mer, en montagne, par ciel couvert et lointain. Il réduit l'excès de bleu à l'extérieur par ombre découverte sous ciel bleu. Il s'emploie sans modifier le temps de pose.

OBS

ultraviolet : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2006).

Record 5 1996-04-04

English

Subject field(s)
  • Analytical Chemistry
CONT

... monochromatic UV photometer available from Du Pont; similar designs are widely used in modern LC. UV radiation at 254 nm from a low-pressure mercury lamp shines on the entrance of a flow cell and is transmitted through this sample cell and strikes the analytical prototube. Radiation from the source also is directed through a neutral-density filter, and then to the reference photocell. Current from these photocells is fed to log amplifiers, which generate an output linear with solute concentration. The output signal to the recorder normally is attenuated with a simple bridge network.

Subject field(s)
  • Photography
  • Cinematography
  • Optics
CONT

The skylight filter is often confused with the UV filter, because the two do much the same thing. Both are almost colorless(the skylight filter is a very pale pink, while the UV filter is a very pale yellow). Skylight filters generally absorb a bit of blue light along with the ultraviolet, and they are used to remove the bluish cast that appears in color photos taken in the shade or on overcast days, if the cast is objectionable.

Filtre rose livré à l'origine par Kodak pour atténuer, en photographie couleur, le bleu trop intense du ciel ou la dominante bleutée des ombres.
