My camera is a Canon 500d lens efs- 18 200mm (this should be it). How to debug? How to take pictures?

18-200 belongs to the basic camera set. 0.45/ 1.5 is the closest focal length (0.45m between the lens and the subject can still focus). Nothing has three solutions: 1. Spend money on photography classes or lectures. 2. Buy some photography books (SLR photography bible, SLR photography manual). . ) or photography magazine (Kappa, Friends of Photography. . ) 3. Go diving on related photography websites (China Photography Forum, Hummingbird Online. . . The key is to take more photos, read more books (other people's good works) and learn more (at least 80% of the instructions can be understood). You can't find a comprehensive answer in Baidu's short space.
