A month ago I made some test shots of medals donated for the local American Heart Association's charity races and we discussed them in this thread. My contact liked the concepts but when this year's medals arrived they were a completely different color and shape. So, I went with the simple style and changed the background to blue. That's because it makes the red part of the medals pop and because the donor's main branding color is blue.
Setup
The background and tabletop are a single sheet of vinyl printed with a blue gradient. I altered the color of the blue during post-processing to better match the sponsor's branding color. A medium continuous-light lamp was above and to the left of the medals.
