Capturing your business using a professional photographer is a very good idea. Communicate to the world what you do. Give them the behind the scenes activity and maybe even show case your team. I think people are curious of what you do, at least I am. I will often ask, what do you do? Where? and what train to the city do you take? We humans are very curious.
These are very simple images captured with a shoot through umbrella and a shallow depth of field. A lot of the shoot is making the client feel comfortable, which is something I am very good at.
The food photography was shot with a light modifier and a piece of white foam core to reflect light into the shadows.
I love shooting black and white as well. Most cases I will take the raw file into photoshop where I will apply a bw filter.
One of the best parts about photographing chefs, is that they usually let you eat the sample plates!
