I was wondering if you guys could have a look at this zombie gallery (a tad NSFW): http://www.behance.net/gallery/Zombie-Walk-Paris-2010/766679 and shed some light on the post-processing used in the pictures.
I think there is at least some vignetting going on, some fake bokeh/depth-of-field, some extra background textures, and a mix of vintage look + red saturation. Lots of work I'm sure. I'm usually not into post-process, but I think it worked really nicely for this specific subject; I'd love to get the corresponding LR preset and experiment on my own zombie gallery, for kicks.
Note: it's hard to characterize this type of question. I could typically imagine the same question being asked for a different effect. Any hint on how to make it more pertinent?
