I have always wanted to use my iphone as a light source. Today I did just that, it was sort of a pain because I had to hold it up above me and get the lighting right. But I managed to pull it off. It was really surprising to me how much exposure was needed to get the shot. I was shooting all the way up at ISO 6400 and wide open. You can see all the grain from the high ISO but I think it kind of goes with the photo. So my phone put out a lot less light then I thought it would, but its still nice to know that I have a light source if need be.
