I turned most of the photos I took in Calcutta to B&W because b&w suits well for street photography. Also black and white has the capability of  turning any drab photo into a masterpiece. Here are the steps to do it in Photoshop.

First lets start with the original and the transformation.

As you can see it just looks drab and so its not enough. People think turning on the black and white mode of the camera also would produce an amazing black and white photo, but you will end up with something like this.

2) Open curves. Adjust it. The curve should look like an S . you can open Curves by pressing Ctrl+M.

As you can see the picture is starting to pop.  The curves adjustment is enough to make you pics pop.

3).  If you want more, you can play with the Shadow/Highlights and then your picture would be complete.
