Abstract of the Disclosure A light-sensitive composition comprising: 1) a plurality of vesicles comprising lipid mem- branes containing rhodopsin; 2) a mixture of enzymes comprising phosphodiester- ase and GTPase; 3) a first nucleotide capable of interacting with GTPase to form a cofactor necessary for the activation of phosphodiesterase; 4) at least one metal cation selected from the group consisting of Mg+2 and Mn+2; and 5) a second nucleotide capable of being hydrolized to produce a proton, said hydrolysis reaction being catalyzed by activated phosphodiesterase, said phosphodiesterase also being activated by rhodopsin exposed by light in the presence of said cofactor and said metal cation is useful in preparing photographic elements com- prising means for detecting the hydrolysis reaction, such as an indicator dye. Further, a process for forming an image in the photographic elements com- prises imagewise exposing the photographic element to light having a wavelength of 350 to 600 nm, detecting said hydrolysis reaction, and optionally removing the metal cation to render the photographic element insensitive to further exposure.
