Photographers are a persistent bunch...we'll climb mountains, crawl through tunnels, bake under the blazing sun or let our fingers get so cold it's hard to press the shutter release all to get the perfect shot. Viv Porteous's stunning shot which opens this week's picks is a perfect example, as Viv says, 'this picture was almost 4 years in the making' until all the elements were perfectly aligned. Congratulations to you Viv, and to all the other photographers who've contributed to this week's brilliant collection.
