Photographer Brian Rueb was approached by two friends to shoot their wedding - a familiar proposal for many photographers. However, there was a slightly unusual twist in this case, as the couple planned to tie the knot on top of Half Dome in Yosemite National Park.

For those unfamiliar, Half Dome is a 4,737 ft granite rock formation rising above Yosemite Valley. Anyone planning to visit the top can either climb a sheer rock wall, or make a trip up the slightly sloped east face with the help of some braided steel cables attached to poles that are fixed to the rock surface. 

Determined to help his friends document the occasion and face his fear of heights, Rueb made the eight mile hike with the bride and groom to the Dome. Suffice to say the trip up the cables wasn't an easy one for him, but he made it to the top for a truly unique wedding shoot.
