Nikon SB-600 Flash Color Filter Adapter (Vivitar 2800)

This is a bit of a niche gizmo. It adapts color filters from a really old Vivitar 2800 flash (http://www.ebay.com/p/Vivitar-2800-Shoe-Mount-Flash/99568346) to a not-as-old Nikon SB-600 flash. The fit is great on my make. I'm still figuring out how best to use the filters, from a photographic perspective.

The adapter collar can also serve as a platform for other flash modifier projects.
