Shooting into the sun produces dramatic photos, if you are careful. The sun has to be partially blocked by something, usually a tree. Even so, the lens sometimes adds “interesting” optical effects. The star-like rays are a product of the lens diaphragm that controls the aperture, with a ray for every corner where the leaves of the diaphragm meet. That’s a nice effect. Prismatic effects produce odd splotches of color, and those are not so nice. A little Photoshop® retouching helps a lot in those cases. This photo of the dahlia garden in the Mendocino Coast Botanical Gardens shows the benefit.
