A DSLR always gives better quality of pictures than a point-and-shoot. The difference is evident while shooting in low light; with proper lenses and settings, a DSLR delivers superior results. Most DSLRs have a battery life of over 500 shots on a single charge. The point-and-shoot cameras usually allow 200 shots.
