he is a subject of many discussions on FLICKR, you might want to try a search on google for "Dave Hill" effect or try searching some of the numerous posts on FLICKR itself
Dave is a great photographer, and his style and processing technique have indeed been discussed (at considerable length) on the internet for quite a few years now.
Matt Hoyle is another great photographer, with a slightly similar style, who was also much-talked about online a few years back.
I found some great post about Dave Hill photography at digital-photography-school. It contains tutorials about creating some great effects in Lightroom. May be useful for Hill fans
