You don't need an expensive camera, everybody can start with just a simple 4 megapixel digital camera. Next look at other people's work, see how others make their photos, watch photo web sites, read photo magazines, try to find people with similar thinking to yourself.
Finally, and most importantly, don't be afraid. It doesn't matter what camera you use, the main thing is to use your ideas!
