I have found that there are several methods of converting a color photo to black and white. I've also found that one method doesn't work ideally on every conversion. It's been a matter of matching method to the source image.

In photoshop : go to Image>Adjustments>Channel Mixer , click on Monochrome box and adjust the Red,Green,Blue sliders to your liking , don't forget the Constant slider . Some times you have to use the Dodge & Burn Tool. There is moor but Im not going into that right now. This Image can also use some cropping off the top and bottom .
