Computer Art is split up into three levels. They are Computer Art A, B, and (availble in 2008 and beyond) C - of course the lowest level is A and the highest for now is B. I'll be discussing A and B because C is not a class yet.
Computer Art A teaches the basics of using Adobe Photoshop CS to enhance images. The fundamentals of Adobe Photoshop. You create simple enough designs and what not. Follow simple outlines and rules in packets to make the assignments in computer art. Last year the students got to keep the packets for all of the projects - hahaha :), now the packets are given to the students to use but they have to return the packets back- at least the packets have color though for them - that's the only thing that the newbies get and a 3 ring folder.
