After failing to interest a manufacturer in his idea, Henry knew he had to do it himself. Things took off in 2007, when Henry met Tyler Kope, who helped Henry refine his idea and file for patents. The two moved on to production, then took some prototypes to Glazer’s Camera, a Seattle retailer, where the accessories buyer gave it a thumbs-up. Advertisements on digitalweddingforum.com began to generate online orders. Encouraged, Henry and Kope took the strap to the 2009 Wedding and Portrait Photographers International show. It was an instant hit, though some were put off by the $54 price. “It seems high for a strap,” Henry says. “But once photographers try it, they realize it’s a great investment in their shoulders and neck.” And perhaps in their readiness for an unexpected shot.
