DEF

Lentille additionnelle. Bonnette. Lentille fixée devant un objectif pour en modifier la focale. On l'utilise, en général, pour photographier à une distance ou à une échelle que ne permet pas l'objectif dont on dispose. Les bonnettes négatives allongent la focale et donnent la possibilité de photographier à une échelle plus grande. Les bonnettes positives raccourcissent la focale et la distance au sujet peut ainsi être réduite.

OBS

Bonnette. Terme impropre employé pour désigner : lentille additionnelle.

OBS

Lentille auxiliaire. Terme impropre pour désigner : lentille additionnelle.

Record 9 1985-10-24

English

Subject field(s)
  • Photography
CONT

The simplest way is to add a positive supplementary lens or "close-up attachment" in front of the camera lens. This has the effect of shortening the focal length of the camera lens. As focal length decreases, so does the minimum focusing distance. Therefore, the lens can be brought nearer the subject and the image will be proportionately larger.
