Low saturation style

This is one of the picture taken during my sister's solemnization back on December 2009. The sun was on their back making their faces under expose in the original version of this picture. 

But by;

1. Duplicating the layer, change the first one to black and white -> change blending options to screen.
2. For the upper layer or the duplicated layer/2nd layer ->change blending option to overlay.
3. Adjust your opacity for the layers to your taste.
4. Adjust the colour to your taste after you flatten the image.

Sorry, I didn't have the time to take a screenshot of all the steps.But it's pretty easy~~~
