I was a hunter once. It did not work for me very well. I admire the folks it works for, but it's just not for me.
I prefer the studio now. Actually, I sit down and sketch by hand (yes, pencil and paper) and put down what I want to create photographically. I guess Keith would call this 'previsualization'. Then, I send these sketches to a few models, who I think would be ideal for the job. After mutual agreement, we get together and try to replicate the sketch and envision the print, at which point, things may change quite a bit, because there is more visual information. Keith, help me out, this must be the 'visualization' part, right?
I attached an example.
