Real. Although, I would prefer real settings. Professional photographers typically use a mix of backdrops and real settings. Almost always, real setting are preferred.
I would also prefer a photographer who knows how to use a camera, photography composition, angles, light, manipulation, exposure, aperture, lenses, and all the other things it takes. I would not want a mom who bought a standard DSLR with a standard lens, who is not educated about photography. It's more then pointing and shooting. I don't know what you've learned about photography. It may be a lot, or a little. If all you know how to do is shoot on the preset automatic settings, you shouldn't be charging for your work. If you only have one lens, and have no idea how to manually operate your camera...you should not be charging.
I come from a family of photographers. There is nothing more maddening then a mom who buys a camera, and thinks they are a photographer. The pictures don't lie.
