Ok, so I needed a cover photo for my master's thesis report. It needed to look good both in color and black and white for printing purposes. I wanted the photo to really capture the reader's attention, with focus on the vehicle and not the background, so I shot at f2.8. I also wanted the photo to show the behavior of the vehicle, so the vertical trees in the background really give a good reference to the roll angle of the body to show the vehicle is cornering. Basically I just took the saturation of the green and yellow channels to -100. I usually try to never do any local adjustments, but I did in this photo because the ramp in the background was distracting.
