Post-processing pics from the auto show can be interesting. Certain images you think you really nailed, only to find out later that the constant changing lights or ever present people have ruined the shot in one way or another. That's pretty much what I was expecting here, but this was actually came out pretty nicely. Above this new E-class were the rows of square panels that changed color, the projection screen that kept switching to new images, and various sets of lights that would dim, change color, and move direction. Not such a big deal for a single shot, but it did add complexity for the series of shots combined for this HDR. - charliesphotoblog
