Here is a real world example of “Professional Photography”. Santa stopped by for a photo op with the kids. I was visiting the dentist which is in the same mall, so I took a couple of photos on the way from the dentist’s office to Walmart.
They are using a Nikon D90 with Alien Bees B1600 flash and a shoot through umbrella!?! No idea who set them up. I don’t even know if they are from the camera store in the mall or Walmart’s studio. I think those are the most likely sources. I don’t think the mall has a dedicated photo studio tenant.
Pretty sure they are raking in the case though.
