Traditionally a company's website might have a scrolling page of head shots with a short blurb with each person's bio. This is very useful and efficient way of showing every member of staff. Presenting your staff only as a mosaic of smiling faces misses an important opportunity to communicate with current and prospective clients.
Showing the "Team At Work" on your website communicates more than just competence, it can show your organization's personality.
The trick to making these photographs successful is to make them feel as natural as possible. For these images I use minimal lighting that looks natural and allows the camera to move around the action, and ask the subjects to pretend it is a normal day and I am not there.
This last part can naturally be the largest hurdle because the normal work day usually doesn't include a photographer, a photographer's assistant, and flash bulbs firing. But, if I take my time, give them some props, some minimal direction, and let them talk about their work, people will fall into their normal banter and I can get the best images.
