The stop motion project sounds interesting, will probably have a look into that when I have a bit of spare time. Tbh, I'm a bit fed up with HDR, it's become so common and overused that any meaningful application tends to pass by unnoticed by me! It also seems to be a way to hide 'average' photos, shall we say! I guess that's similar to what you're saying about the workborks as well.
I'm in two minds about doing a course. Having almost completed a three year engineering course I can't help but feel that three years spent as an apprentice or generally in a more practical, work-based application would have taught me more. Think that's where you're saying a ND would be better suited.
Thanks very much for the insight anyway pal, it's much appreciated. It's definitely something I'll consider once I've finished my course, especially if I can fit a job in at the same time. What are you planning to use the qualification for when you're finished by the way?
