I am learning different graphic software from Internet..I have started learning just before few days.Here I am little bit confuse that 'How does presentation-graphics software differ from multimedia-authoring software ?'Please share your thoughts regarding to that difference.

OK so you want to learning from Internet but i suggest you to learn adobe photoshop ,adobe illustrator,and corel draw. try to learn this graphics software. it has all the tool and features and the latest adobe photoshop has 3D tool also.

Ok I agree with you that photoshop, illustrator and corel draw is good graphics application but now a day I think maya is very nice application for graphics creation so I suggest you to learn maya.

According to me there are lots things to do in a graphic software which includes randomly interesting graphic challenge, new digital paintings as well as corel digital, are the best. While, taking about the multimedia software, is best if you are interested in the creation of business presentation for which adobe and dreamweaver are the best.
