Thank you for the comments. I took this shot with a single exposure, the National Geographic Your Shot community has its rule to follow to create a photo with your creative and idea not by the power of the modern software of your computer. What I did was set the shutter speed at the lowest which you can still shot at handheld position to blur the opposite speeding train and I use the glass reflection to have the effect and slide + of the saturation slider of the lightroom to enchance the photo..God Bless!
must have been at least 4 exposures...very nicely made, but I wonder if it wasn't set in post-production-process
This has to be a in-camera double exposure that both Nikon and Canon
supports now a days. I would love to see more documentary kind of
multiple exposures like this one.
