You might be accustomed to taking pictures with your digital SLR by using both of your hands, but have you considered how difficult this might be with only one arm? The OHSnap is a clever camera add-on that enables you to capture fantastic scenes in high quality for those without the use of one of their hands.
Xing Dawei, who also goes by Dave Xing, submitted this idea to the 2013 Red Dot Design Awards. The concept winner is a flexible silicone elastoplast band with an embedded auxiliary shutter button. A fine wire extends from the control and plugs into your digital camera. The OHSnap strap fits snugly around lenses of various sizes, placing the button in the ideal spot for maintaining balance, adjusting zoom and focus and enabling you to modify for shutter speed and aperture.
