When a partly developed image is briefly exposed to actinic light, the final developed image becomes reversed. This is because in areas where the negative image had started to form, the emulsion is desensitized by the oxidation products of development. The result is that the extra exposure affects only the shadow areas of the original negative so that the final image is a positive.

Initially, a black and white, silver halide, latent image is chemically developed to form a negative on all three layers. During this stage, the developer used to convert the exposed silver halide to metallic silver becomes oxidized.

A yellowish-brown image color or stain produced on photographic films usually as a result of improper fixing and/or washing. The residual silver that results from insufficient fixing reacts with sulfur in the air or on the film to form silver sulfide. The residual hypo(thiosulfate) remaining on the film after washing breaks down and combines with silver to form silver sulfide. This phenomena can also be caused by improper chemical eradication techniques.  1, record 38, English, - sulfurized%20image

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 46, French, - d%C3%A9veloppement%20par%20inversion
