This image has been the selected from the following set of images. In the images #66 and #68 a flash has been used as "fill-in" in order to regulate the light of the window in the right. Initially I selected the image #68 considering that has more soft colours due to "fill-in" flash. Later I like more the image #62 and #63 and the final image above is the image #62 (without "fill-in" flash). The feeling of grain is due to the digital noise of the camera sensor (Nikon D700), because the image has been shot in high-iso (6400 ASA in order to have fast shutter speed and regulate the train vibrations). I have also upload this image for the National Geographic contest of 2013.
