Whats the best camera you have? The one you have on you. On my drive home from work this morning I travel through a lot of countryside. This morning the sun was just rising and a low level mist was drifting along the ground. As I turned a corner I came across these horses out grazing and I knew I wanted to capture the image, my camera though was at home some twenty miles away. So I used my iPhone, uploaded the images to my PC and tweaked them a little.
Sometimes what you have overrides what you need to capture that moment, don't get bogged down in having all the right "kit". Open your eyes first and the rest will follow.
