Unfortunately for right-handed folks, sometimes you require your right hand to be doing something in a photograph you take, and dSLR cameras are not left-hand friendly. With just a simple DIY attachment, however, you can make the task a bit easier.
All you need for this minor tweak is an aluminium strip, a drill, and a screw that will fit into the plate on the bottom of your camera. By bending the strip into a hook (big enough to fit your thumb into), drilling a hole and screwing it into the bottom of your camera, you can now easily hold the camera upside-down and press the shutter with your pinky finger. It's effective, if not the most ergonomic solution, but if you need your right hand in the picture (say, if you're writing), you don't have many other choices short of finding another photographer.
