How To Get A Starburst In Your Photo
A question I get on a regular basis is “How do you get those cool starbursts in some of your photos?”
People have speculated on everything from special filters to photoshop to alien intervention (OK, made that last one up) – but it’s way easier than that.
To get a starburst in your photo, you just need a DSLR and a couple steps:
1. Set your F/stop somewhere between F8 and F16. Generally the smaller the opening (f/16) the more dramatic the starburst. I personally start at around F/11 (aperture priority) and that seems to work pretty well for most of my starburst attempts.
Tech Note – Going much past F/11 or especially F/16 starts to introduce too much diffraction, softening your overall image (yeah, yeah, I’ll do an article on diffraction one day).
2. Get the sun against a hard surface. When the sun is right against a mountain, horizon, rock, or even a tree and and you’re set in that F/11-ish range, it should produce a nice starburst. No special gear or processing required The aperture of the lens itself produces the starburst. (NOTE – yes, I’ve seen images where the sun was not against a hard surface, but in my experience starbursts are easier to capture when you use the “hard surface” rule.)
So, what actually causes the starburst?
The starburst is basically created when the light slices past the points on the lens aperture where the blades physically overlap. The more blades your lens apature has, the more points your starburst has.
Again, keep in mind that different lenses and even different focal lengths within the same zoom lens can produce different effects. At this point I’m pretty familiar with how my main lenses will respond when trying to produce a starburst, but that wasn’t always the case.
If you’re new to creating starbursts (which you probably are if you’re reading this ), then my advice is to quickly check the photos on the back of your camera as you shoot. Try different F/stops and focal length combos until you see a starburst you can be proud of!
Oh, and as always, your comments and feedback is appreciated :)
