Method one suggested, was the use of canopy high walkways.
Not to be recommended if you suffer from Vertigo or have problems with balance. We found the best method of transversing these often swaying and oscillating suspension bridges was to crawl along them on all fours. This of course made it difficult to focus the camera!
The second recommended method of getting close to the canopy was--
-- Zip Wiring
The main problem with this method was the effect on the canopy's fauna of my dear wife screaming constantly whilst we travelled at high speed across the top of the forest. Thus defeating the aim of getting close to any wildlife. Additionally holding the camera steady proved difficult!
After further experimentation we concluded that a gentle walk around the grounds of our many hotels produced the best results.
We hope you enjoy our efforts.
