One of my favorite observations by a now-forgotten sage explained the difference between writing and photography like this: A bad sentence can be massaged, but nothing helps a bad photo.
So true. However, I’ve experienced for myself how a good photo-editing app can salvage sloppy composition or bad exposure — and even teach you something along the way. So if you resolve to become a better photographer in 2017, you might want to add some tools to put a finer finish on your iPhone photos.
