One of the stranger and more interesting artifacts you’re likely to come across in photographing nature is the sunstar. You’ve probably seen the effect, or one like it, where bright points of light. While many of these effects are the result of ::amazon(“B00004ZCDV”, “specialized star filters”)::, effects like this are, in some situations, easy to create without a filter due to a strange quirk in the physics of light, the phenomena of diffraction. Fortunately, you don’t need a degree in physics to get sunstars in your own photos, just a few simple tips. (more…)
