This fantastic video by photographer Rob Whitworth is what he calls a "flow motion" look at Barcelona, Spain. Whitworth says,
"In few other cities is it possible to walk from spectacular location to spectacular location. I had a fantastic time adventuring around Barcelona's winding streets making this film."
By Whitworth's own account, the video took him 363 hours of work, which involved 75 hours of logistics and travel, 31 hours of location scouting, 78 hours of shooting and 179 hours of post-production. He used 26014 RAW files, 817 gigabytes of data and four Nikon DSLRs.
