He had already done a management course while working and hopes to go into systems engineering.
A year travelling to Australia and an uncle who was a cameraman for NBC news gave Dave the ambition to make documentaries abroad.
Before starting the HND, he did an Access to HE Media course, which enabled him to build p a portfolio of small projects on sound, as well as moving and still photography.

Between them, they have clocked up a good range of work placements through the Ravensbourne course, including Wimbledon, shadowing a news team with Carlton, working on an outside broadcast truck and going with Sony Broadcasting to the Amsterdam trade fair.
