Well, today, I tried something different. In order to isolate my subjects, I shot with a long telephoto lens (200mm f4 Micro-Nikkor, manual focus), which allowed me to focus on details of various air and space craft. I cropped tight enough that the identity of any given aircraft is not obvious. I also used a strong flash. This allowed me to close down to smaller apertures, increasing depth of field, but more importantly allowed me to make anything in the background go completely black. In other words, I only lit what I wanted to see, and the ambient light in the background was too low to show up in the pictures.
Here are a few of my favorite results:
