The key to getting this nice and soft pink coloring on your image (as in any other effect mostly) is to start with a good photo. The one that has enough exposure and contrast. This is like the rule of thumb or something. After that, your post processing step is just downloading the free PSD file offered here, open the file in Photoshop and drag the layers above your image. You can do a little tweaking on the opacity of each layer to get the desired coloring effect for your image. I have come to believe that this pinkish and classic coloring works well with portrait to emphasize the softness of the subject.
