Saw the stuff this chap did at London Olympics and that was really interesting. Not so sure (as a Brit) I know enough about the candidates (apart from that pillock Donald Trump) to get the best out of the presidential race. That said, I will check it out as good photography is good photography.
Also, I'm with Nigel on the photo manipulation issue. I even use Silver Efex Pro on scanned film (occasionally). Not to add grain but because some of the presets are just extremely good at converting colour to B&W, balancing out contrast, adding contyrast and they're a lot quicker than I would be using Photoshop. As Nigel said, different strokes for different folks.....
