It's just called Digital Photography - An Introduction
There are Intermediate and then Advanced courses that follow on, but none are certificated or externally validated. They are evening courses to introduce and develop generic photography knowledge and skills with no pretension to being relevant to career or job, just for interest. However the college/faculty does teach HNC, HND and degree courses, and maybe one or two people might go on or over to those, but most of the students on my course at least are mature, not looking for a new career or even to make any side money out of it, just to develop their hobby. That's one of the nice things about it, because there's no pressure to deliver particular course or home work for any assessment.
