iPhone 4S is blowing my mind. This one was edited using Filterstorm. There is a Pro and a non-Pro app in the store and I’ve linked to the non-Pro version. The thing I love most about the app is that when you apply a filter or edit, you can also determine the layer mode by which it is applied. So for an edit like saturation, you can apply the saturation and then set it to a mode like Multiply or Overlay and you get dramatic results. It’s something that I’ve used to get pleasing results in my iPhone sky shots, this one included.
