I must admit here that, 17-40mm f/4 L lens is an excellent piece of glass, which not only reproduces super sharpness but also an excellent color. I strongly feel that the color in the first photograph came so well because of this lens.
The second photograph was a little tricky one. With a small tiny point and shoot camera nothing much you can do while shooting. I wanted to give it a feel of something different. I have set the camera shooting mode in "dusk" , which means it changes the white balance in the camera settings. It was early in the morning, probably at 5:30 AM, not much sunlight though, Chennai Express was about to go off the platform. It was a last minute check up with the reservation list pasted on the train compartment by a fellow passenger, while some others were boarding the train. Due to a slow shutter , it gave me a ghostly image. Enjoy.
