While I was up in the Arctic Circle in Alta (Norway) I was lucky enough to see the Northern Lights, or the Aurora Borealis. Unfortunately I was in the middle of a load of lights and they were appearing straight above me, so I don't have the most beautiful pictures in the world, but I think they're pretty stunning nonetheless.
Now I don't have a fancy DSLR camera (yet!), so my iPhone was my only chance at getting a shot of them swooshing around in the sky. I'd seen that other people have really struggled to get shots in the past with phone cameras, as you really need to be able to manually change the shutter speed of your camera to catch them in action, and iPhone camera says no. I downloaded an app for 79p called Northern Lights Photo Taker, and hey presto it worked! The only problem was that it was about -8° and my fingers were nearly falling off, so because of the slow shutter speed my photos are a little blurry... but not bad for less than a quid, right?
