I know a guy who does real estate photography as a company employee. They give him a Canon 350D & he goes to a house & blasts away & then uploads the files to the company where their digital employees do the finishing touches. They correct any convergence, stitch images together etc. The photographer is just one cog in the machine, something I'm still coming to terms with. I think most of us are accustomed to think of the photographer as the sole author of their production but that is less and less the case these days. So yes, real estate, architectural & other genres of commercial photography may be looking worse but it's not a simple case of being able to pin it on the photographer anymore. It's the system, man.
