Le principe de l'inversion. Rappelons d'abord brièvement comment l'on transforme l'image latente négative enregistrée sur un film en une image argentique positive. On parle à ce propos de "développement par inversion". L'expression est assez incorrecte puisque l'inversion n'est en fait qu'un ensemble de deux opérations précédées par un développement classique, et suivies par un second développement. Nous parlerons de "développement-inversion", construction lexicale sans doute peu heureuse, mais techniquement plus satisfaisante, du moins nous semble-t-il, ou mieux "d'inversion directe" par opposition à l'inversion indirecte (en deux temps) des procédés négatifs-positifs. 1, record 5, French, - d%C3%A9veloppement%20par%20inversion
