Macro images often show detail not visible to the naked eye. Captured using a screw-on filter, this is the refracted image of the montbretia in a water droplet. There is a very narrow band of sharp focus, maybe only 1 - 2 mm, which falls away in front and behind it. Unless chasing the higher quality benefits of a macro lens, very good macro images are possible relatively inexpensively. As a generality, I try to capture the subject in a more creative way rather than in the style of images destined for study or for reference books etc which may demand macro lens quality.
