My readers know I have been in wildlife photography for a long time. When I am on a photo shoot anywhere in the world, the best laid plans of mice and photographers sometimes go awry. Airplanes, boats, jeeps or other vehicles can get delayed or run into engine problem. Photographic gear and computers can malfunction and put out indecipherable error codes.
Like the wise man say, 'Feces Occurs'. For me, the best defense against expected and unexpected problems is - Back Up. I usually pack duplicates of everything in my equipment bag that is crucial to the photo shoot - cameras, lenses, batteries, memory cards, etc. and especially credit and ATM cards for overseas trips.
The video from DigitalRev below shows some of their photography bloopers, some genuine, others probably manufactured. Nonetheless, a bit of levity and entertainment rarely hurts.
