It took me quite a long time Rob, I used an app (colour splash) to give me a head start by bleaching out most of the colour on the phone itself and then used the adjustment brush in Lightroom to fine tune the image. Must admit, I am very impressed with the iPhone camera, nice and easy for wrist shots.
I find that the trick with the iPhone is controlling hand shake, the touching of the screen seems unnatural and the new way of pressing one of the volume buttons had me all over the place, the other thing I do is dance around the subject like a drunken Comanche taking gazillions of photos and then being really strict with the weeding process, 9 times out of 10 I will only end up keeping 1.
I was pleased with the way this one turned out, all I ended up doing was cropping it in quite close.
