Heading for the light

There's always something going on at the airport. I'd stopped in on this occasion to view a photographic exhibition... and take a few photos with the iPhone.
I grabbed a free app called photo editor so I could retouch out a distracting piece of rubbish that was on the floor. The app has just turned it into a darker fuzzy blob (below the man on the left), and I also used the app to convert the image to black and white.
