Natalie Mayer, judge: This is a beautiful image, lovely exposure for the silhouettes, and perfectly captured action. Nice tones too, very appropriate to the vintage feeling of the whole scene. Lovely stuff. Photograph: Chris Mole
Natalie Mayer, judge: This is a cracker, a real contender for winning, but the three top images this month were all excellent. The grain, black and white, action, watchers on, light and shadow ... all well executed and compelling. It can be difficult to capture good action under these circumstances, but the photographer has shown an excellent understanding of exposure, and timed his shot perfectly for capturing the wallride at its peak (nothing like half a second too late for ruining a nice trick). Nice one! Get it printed on some nice textured Hahnemühle paper – it'll look fantastic! Photograph: Renato Lainho
Natalie Mayer, judge: Sweet composition and sweet air reverse! I really like this image – it has a great element of surprise; you don't see the surfer immediately, but when you do, the action is strong and stylish, and perfectly captured. All this really justifies the strongly unbalanced composition and makes it work. It fits really well with this month's adventure theme too ... the rough sea, ominous looking shipwreck, moody exposure and tones. All spot on.
