It’s not the sort of information that gets publicized by artists, or galleries, or curators, or historians. It’s largely irrelevant to the kind of conversation happening in art.
The kind of people who would need to know what specific materials an artist used would be conservators or archivists. People personally working hands on with the materials in a technical capacity.
But an audience member asking what kind of developer a photographer used to achieve a certain effect is sort of like asking who manufactured the canvas Van Gogh used to paint The Starry Night. It’s the wrong line of questioning to follow when interrogating the work.
And for an artist looking to take inspiration from the decisions contained in the work, it’s the wrong aspect of the work to be inspired by. Emulating the techniques of another artist is one thing but when it gets down to the level of what materials they used it becomes an unintentional attempt at either parody or forgery. Either way not really something of interest to art. Better to make your own decisions based on the needs dictated by the conditions of your own ideas.
