Liminal spaces are endlessly inspirational to artists, and it’s no wonder, with all that neither-here-nor-there quality and interplay of light and dark. Singapore-based photographer Weilun Chong is no different. In his intriguing series “Please Mind the Gap,” he captures commuters just as they’re stepping onto or off of a train, their bodies straddling that gap, always going somewhere. According to PetaPixel, where we spotted the images, Chong is currently working on a book of the series. Check out some great shots after the jump, and then be sure to head on over to Chong’s website to see more of his work.
