Its not a matter of any sort of magic ratio. The females that I can choose to work with of any body type are the ones that contact me, or who respond favorably when I contact them. From the ones that write me I look for people that look comfortable in front of the camera and have a wide range of poses in their arsenal.
Unfortunately there isn’t a very large number of “chubby” models out there that do nude work, and of those not every single one of them likes or is interested in being a part of my work.
I would normally spend more time on a question, but I’ve answered this before, and I’ve been traveling for two months taking care of this all on my phone. When somebody says something that shows me they haven’t taken the time to look at my work, I don’t feel particularly inclined to take the time to give them a long answer.
The idea that photographers can just shoot some specific body type whenever they want is not very realistic, especially if you’re talking about experienced models. It’s not Weird Science here. There are a limited amount of models out there who have the kind of qualities Corwin mentioned, and the pool is fairly self selective. The experienced models are going to be the ones who are shooting a lot and making their living modeling (or at least a good portion of it), and they are going to tend to be on the thinner side.
There are so many things that go into whether two people work together or when, some of it is pretty close to random chance. Photographers are not nearly as much in control of this situation as I think some people imagine, at least those of us who aren’t wealthy or super famous.
Beyond all that, the idea that a photographer should be shooting a certain type of model because someone else thinks so is just really misguided to me. We all have our own reasons for shooting what we do and our own ideas we’re trying to express. Those differences are what makes our art individual and personal.
Ironically, Corwin is someone that I’ve seen push the envelope a lot more than other photographers, in terms of the types of people he shoots. So seeing this sort of criticism directed at him really makes me scratch my head.
