Thanks for the reply. My father in law is a company director for truck body building outfit and he has been quite supportive of my ambition, to the level that he has suggested at some point in the future I could do some of the photography for any magazine write up's for his products. Therefore I would like to explore transport photography. I do not want to limit myself to this particular niche as I like portraiture and landscapes.
I am scouring the Interwebnet for suitable courses on a regular basis but it's difficult to choose purely on their advertising bumf! I am going to request a full itinerary of the course to help make a decision.
I like your idea about shadowing a pro, I happen to work with a fella who does weddings and portraits (he is just always so busy) so I may ask him
