I first tried to shoot with a softbox on the flash unit, but the dull colours and the subjects plain T-shirt made it a pretty boring shot so I decided to shoot without any form of light modifier and removed the softbox in order to get the hard shadow.
The flash exposure was f5.6 at 200 ISO with the softbox in place, but this leapt to f13 with just the metal reflector in place. There was so little available light that everything not lit by the flash was in total darkness. This effect was perfect for the shot. The subject had turned up with few tools and the shot needed a prop or two so we borrowed some plasterers tools and got him to hold them in a way that seemed to relax him. When you are photographing people that are not used to having their picture taken professionally you often need to work as hard at relaxing them as you do in getting the technical bits right. Having some familiar props (teddy bear substitutes) to hand can make all the difference.
I worked hard with this image at getting the composition right by using the arched frame, I tried a couple of other shaped holes too, but this was the best. Getting the shadow in the right place is nothing more or less than trial and error, but using the LCD on the back of a digital SLR helps to shorten that process. I started the shoot working with a 28-70 lens but graduated to a 17-35 pretty quickly. Getting closer to the arch gave me a larger area inside the room to work with and having a six foot tall man, his shadow and some plasterers tools I needed that space.
I think that this photograph helps to demonstrate just how useful adding extra elements into a portrait can be. The props and the shadow help to tell the story as well as making the whole image that little bit more interesting. In the end the picture ran in the newspaper in black and white and the contrast provided by the shadow really helped.
