I have a corporate client that uses these kinds of photos in their marketing endeavours. This is Scott; who I know through other channels besides photographically. There are a couple of ways to achieve this kind of photo; you can photograph the subject against an all white background or you can use a chroma key background (these are usually green) and cut the subject out after. Because I took this on site and not in a studio and I did not want to lug along a bunch of extra backdrop stuff I simply positioned Scott in front of a fairly plain wall. I used to Elinchrom strobes triggered remotely to light him. Then, I digitally 'cut' Scott out using Topaz Remask software. Then I placed the cut selection onto a white background.
