If I had the choice I would hire Greg Shapps as the photographer for my ad because his use of lighting. I wanted the shots of my mp3 player to be bright and glowing as if shadow didn't exist. Chris Collins' work seems to be based on his use of shadows and dark to light gradient which is exactly what I didn't want to happen in my ad. I fought very hard to erase any hint of shadow from my shots. Greg Shapps seem to enjoy making every color stand out. I wanted this effect because my subject was generally different shades of a metallic blue color, so I tried to highlight each shade as much as possible. On the other hand Chris Collins seems to be satisfied only with shadows, which is an obvious bad choice for my ad.
