Regular iPhone camera shot above. The app does make a big difference.
You really have to hold still for a longtime though.
Tried again, but sharpened in Snapseed. It would have been nice if there was sharpening available in the ProHDR app.
And finally, I said 'screw it' and added filters in Camera+ and FX Photo Studio. One thing I particularly like about FXPS is that you can paint on or paint off effects with your finger.
Hmm... I wonder if it's appropriate taking a picture of my Blackberry with my iPhone!
