There are several photographers that have used the iPhone as their capture tool. The resolution isn’t very good, no zoom (on mine anyway) no flash just kind of general Lomo camera. That’s what I find so interesting about it. You always have your phone so there just isn’t a reason to capture images right now.
I have fun in the editing department using a combination of Photoshop/Lightroom along with several standalone apps made for the Mac, iPhone or iPad. I haven’t seen the new iPhone but I hear the resolution is much improved and that would be good. I like having too much information so I can achieve my goals by taking away not puzzling over how to “fix” the photo. This shot is called “chair.”
