Photographer Natalie Mayer said: 'These days, with everyone doing their fair share of travelling with a camera, there are many obvious 'travel' shots which have become cliches as a result. I think the trick is to not forget to capture 'moments' rather than just staid shots of people abroad that we have all seen before. This one really stood out as having caught a nice moment in an clever and simple way. I like the composition, and I like the mystery - what are they looking at, cheeky peeping lads?! The shot has a nice documentary feel - you really don't feel the presence of the photographer - as the viewer, you are spying on the boys who are in turn spying on something else, and it is all done very unselfconsciously. I like that. Photograph: Oliver Shaw/guardian.co.uk
