Tim photographed good friend and fellow Nat Geo photographer Christian Ziegler working on a story about Panama’s balsa tree. National Geographic magazine published Christian’s story “Open All Night” in May 2011. The story was also published in National Geographic Germany’s July 2011 issue. They used two of Tim’s pictures of Christian working from his tower in the canopy.
Tim and Christian also were on a team of 4 photographers that shot a RAVE on Bioko Island in 2008 for a Nat Geo story. You can see Tim’s Bioko Island pictures in his online archive.
