Christmas Market, Edinburgh

I have been testing a new night photography app for my iphone.  This is called the Cortex Cam.  I am quite satisfied with it but will continue testing. This photo was taken without a tripod and has very little blur.  I found it hard to control the very bright highlights.
If any of you know of good night photo apps for the iphone: Please share.

The Christmas market was a great place to photograph because of all the colorful lights and the movement in general. Beautiful evening here!
