I had a stroke of luck a few months ago when I was contacted by an Ad Agency representing Canon to shoot an online commercial for a new (secret!) SLR, which turned out to be the 7D. They wanted a wildlife stories within Europe to be shot in the space of a few days. I tried to persuade them to do an underwater story, but the lack of a housing was a bit of a drawback, as well as the specialised nature of UW photography. In the end they liked my suggestion of the Camargue as a location, and we spend a fun few days wading in the mud, being bitten by mosquitoes, and chasing wayward horses. Having the choice of any Canon lenses I wanted to use was a dream come true- the 800mm f5.6 was lovely.
The 9 minute video of the story, along with pics etc is up here: http://www.canon.co.uk/takestories
I have posted a load more of the stills from the trip on my website http://www.ferguskennedy.com
Another cool aspect of the experience is that Canon are using my stills for their add campaign, so they're in lots of magazines at the moment, and apparently on billboards around London (mainly the pics of horses galloping through water). They are also apparently editing a 60 second ad for TV for Nat Geo channel (presumably Europe only).
Since that I campaign, I was also asked to do help produce a DVD in and around Cape Town to be supplied in the box with the 7D, 50D and 500D. This was also a great trip, and I managed to get in a bit of diving in CT after the shoot was over.
All in all a fantastic experience.
