My D80 does plenty of things I haven’t explored yet. Most of what I shoot is existing-light landscapes, or at least usually not people.
I’m primarily a video person, mostly for stock stuff which pays better than photos in my case.
I’ve used a few people and except for the brightest days, I used some kind of supplemental lighting or reflector.
Since I’m cheap, I rarely rent studio space and based on what sales I’ve had, stick with objects and animals. No release form necessary. Plus my home really isn’t practical due to layout.
Maybe I might get back into hiring talent again if stock video sales pick up.
