Welcome to my office, have a seat! This was a fun shot, actually several shots merged in Photomatix and processed using the Tone Mapping filter. The room was separated by a half door and shelf, which served as a tripod for my camera and wide angle lens. Sometimes we have to improvise!
To enhance the vintage look, and create more depth and drama, I added a layer of texture and burned in the edges of the image. The cracked and peeling wall texture adds warmth, a little grunge, and keeps the background from looking too clean. The added effect is that it creates a more nostalgic image.
You can create your own vintage look by adding a texture layer and choosing a blend mode and opacity that suits your image. Make great pictures!
