Taking photos on a train can be tricky. First, you need to be fast, then you must avoid the trees and powerlines by the track which could obscure your view. And then the lights in the carriage might reflect on the window.
So instead of trying to avoid these things, I played up to them and used phone filter apps to make the most of them.
Take a look at these photos taken on trains in Germany, Czech Republic, Hungary and Slovakia.
My fave photo apps, by the way, are Cymera and Pixlr-o-matic.
