A self portrait session up the Sychnant Pass in North Wales. I had the radio remote shutter clasped to my grip. I was triggering the remote shutter with my index finger and braking with my middle. It was awkward anyway, and then the two different radio signals (one controlling the shutter, one controlling the off camera flash) started interfering. The way round this ended up being setting the camera for a two-second delay, this stopped the remote shutter interfering with the remote flash but left me having to judge when I was two seconds from the place I wanted to occupy in the image, triggering the shutter and then two seconds later (with me hopefully in the right position) the camera would fire with the off camera flash and hey presto!
