Late Night Metro in Paris

Image taken in the RER metro line in Paris. I was lucky that it was almost empty. Only one person was sitting behind me. The metro was riding at that moment.


TECH-INFO: I took 5 JPGs, while riding. I did not use any tripod but instead I have attached my camera on such island on a pole, which you can see in the middle of the image. So my camera made the same kind of vibrations as the riding metro. The longest exposure is 1/3 second.
As most of my images I first used DxO Optics Pro for lens corrections, merged them into a HDR file, tone-mapped it with Photomatix Pro and finally enhanced contrasts and colors in Photoshop. This is done using various layers of the selective color tool, curves tool and blending them in screen or multiply mode to brighten or darken the image. The effect is very similar as dodging and burning but you have much more control. The image is partly desaturated using the B/W tool (set on an opacity of 50%). I think its better than just dragging the saturation down because you can control the effect on colors like yellow, red, blue and others.
To avoid too long exposures I have set my aperture on f/5.6. The focus distance is 1.5m, this causes sharp seats in the front but a rather unsharp zone at the end of the metro. I sharpened that zone using a high pass filter on the copy of the image (set a radius of 5.1 pixels) and blended it in soft light mode with the original image. Then I painted on the layer mask of the high pass filter so that only the center of the image is sharpened, not the front, window reflections or parts containing more noise. I'm pretty happy with the result. Finally some rectangular shaped vignetting is added.
