I've been looking for a definitive catalog of named poses.
Catalogs consisting mainly of unlabeled photos are easy to come by. "1,001 Poses for the Professional Photographer," kind of thing. This seems like a cave-man method of describing a pose. "grunt, Dat one!"
The biggest help I've found so far is in yoga and calisthenics guides. Once you discard all the Hindi and fanciful English names, you get a pretty good list of pose names, names you don't feel foolish using as a Lightroom keyword, or describing to a model. For example, cobra pose:
It's a somewhat fanciful name, but also descriptive, easy to learn, and clear.
Yet, I find myself still occasionally flailing about for a term. What do you call this pose, for example?
The legs are in a pose like you take for doing crunches, but for a photograph, you generally don't want the hands behind the head. I can just call it a "crunch pose" and know what I mean by that term, but that makes me feel like I'm just making things up.
Then you add in the infinite variability of the human form. What happens if the subject drops one knee? Is it a half-crunch pose now?
Despite the variability, I suspect there is a foundational set of classic poses, with most of the rest being variations on one of these.
Every profession develops a jargon. Surely I am following in the steps of other descriptivist photographers who have already pushed a path through this jungle? Where have they put their maps?
