Converting Over/Under Exposed Shots to B&W

I've mentioned in my previous post that I convert my Over/Under exposed shots to black and white when it's not possible to adjust the exposure through Photoshop or Lightroom without totally ruining the colors of the image. I won't be able to detail how I mixed it up through my photo editor since I can hardly recall the exact amount of adjustments I made with contrasts and brightness etc. There is no really exact way to do this but to trust your eyesight and your vision on how the picture should represent the image you have in your mind. You also have to consider that not all pictures converted to B&W will yield nice results. There are pictures that are really made to be seen in color. Below are some examples of the images that I converted through black and white, to the left is the original picture and to the right is the black and white conversion.
