Did a photoshoot of my co-worker's bike that he built from scratch. I love the old school, clean, and simple styling. I decided to experiment with some off-camera lighting in some of the shots. I was using the SB-800 with the Stofen diffuser and had the owner hold it in different locations (CLS trigger). These shots made me realize how much of a difference just one strobe can make. Being able to shoot at high ISO gave me more time to shoot after the sun was set. I also learned that you definitely need the SG-31R if you are using CLS in low light with subjects close up, especially with bigger lenses. The on-board flash was casting shadows from the lens without it. This bike is for sale. contact JP@sovereign-cycles.com if you are interested. Strobist: SB-800 with Stofen diffuser, camera right, triggered via CLS, hand-held by JP
