Dave Sanders managed to choose a much more Ultimate friendly URL than mine, and hardly ever misses a chance to note that Google searches for "Ultimate Photos" favour his site over mine! Our shooting styles are very similar and we've shot together a few times, including at the last 2 World Ultimate Club champs in Perth (2006 ) and Vancouver (2008)

Lee Howell is a Christchurch based professional photographer and was New Zealand's Motorsport Photographer of the year in 2008. Lee is singlehandedly responsible for inspiring pretty much all of my long shutter action photography with a few comments and some advice late one day out at Ruapuna.

Unlike the other photographers here, I don't know Seb Rogers personally, but he's a leading MTB photographer from Britain and anyone that wants to learn a bit about MTB photography, or sports photography in general is well advised to check out his blog (http://sebrogers.typepad.com ) or his main site (http://www.sebrogers.co.uk/site.htm )
