Udi sent in the really cool project that allows you to use your TTL flash off-shoe. Shooting pictures with your flash off-shoe can make for some interesting pictures that would not be possible on-camera. It’s fairly easy to make and will save you about $50.
I bought a flash that supports TTL. I wanted to have a TTL flash cord, something like the Nikon sc-28, which will enable me to shoot TTL off camera flash. After looking at the prices I changed my mind – 45 Dollars for a wire?? The question I asked myself over the next few days was “how can I build a TTL flash cord on the cheap?”
