Camera lenses are full of flaws, which can be bad, but we can also use some of them in a creative way. I’m sure you’ve seen sunbursts in photos but maybe you haven’t figured out how to get them in your photos. All lenses will create the effect when the sun, or any strong light source, shines directly in the lens. But it doesn’t always happen, only when the lens aperture is very small, like f/22, and letting in very little light. Stopping your camera down to f/22 doesn’t always make the points happen either. If you aim your camera directly at the sun, you probably won’t see any bursts. You need to have the strong light source be slightly diffracted by something, like a tree branch, or lamp post.
