The multimedia/photoshop course is more geared to web design than anything else, as for the photograhy courses - unless you want the qualification, look for a photography course at your local community college - a lot cheaper and usually taught by someone who is actually a photographer. Same with the photoshop courses, the community college is usally better value.
Ive looked at the Graphic design course a few times but its too expensive for me right now.
If you choose any if them let me know what they are like
