I find even a few water drops can really make something stand out when shooting close-ups and macro. It can also help with focus, as I find its another part of the image that can serve as a reference when trying to get something sharp. These tulips likely would have looked a but more ordinary or plain if there weren't any water drops on them. This was a few hours after a light shower, so I was in the right place at the right time, catching some of the aftermath.
