What is HDR photography?
The acronym HDR comes from High Dynamic Range photography and basically if you want to make an HDR image, you have to take three photos at different exposure and merge them into a single HDR image. If you want to learn even more things about HDR then I highly encourage you to watch Trey Ratcliff’s tutorial on how to capture and post process an HDR photo. Don’t forget that this is a free tutorial and its available for everyone:
Two electric locomotives
This HDR photo was captured a couple of years ago and If I remember correctly, this one was my first HDR photo. Back then, the Hungarian State Railways (or simply MAV) used some of its electric locomotives for some kinds of testings here in Romania. One day I’ve managed to photograph one of MAV’s locomotive when it pulled a Romanian electric locomotive and some passenger cars. The blue locomotive in front of the train is a Bombardier Traxx which was built by Bombardier Transportation. The second locomotive is a class 47 electric locomotive which is also known as the Dolphin, this locomotive was built by Electroputere in the Romanian city of Craiova.
