The two black and white converted photos have been edited in a way that creates depth-of-field in the photo which of course means that the Jeep in more emphasized and background is slightly blurred.
To blur the background slightly you highlight the background using the marquee tool on photoshop then go to surface blur.I put the threshold on full on surface blur on around 8-12.
Once the blur is complete you will immediately notice the emphasis on the subject,then you need to increase light levels and contrast but not too much otherwise it will drastically look false and almost like a little toy model which is actually and photoshop technique called tilt shift.
