What is This!?

OldNoob · 11-17-2013, 07:27 AM

Guys please tell me this is the lens causing this.
Trying to catch some sunrise photos this morning and THIS happens. For some reason the Sun has been turned into the Star of David! below the pic is a 100% crop. looks like a six blade aperture issue

Cool!!
Does it happen every time you photograph a bright source of light? some lenses because of the diafragm shape capture bright lights in different shapes... although i've never seen one like that.
Maybe you just captured moment where the combination of sun and clouds made that optical effect (it's probably something like that).

it didn't happen every time,, but it did happen a number of times, toward the last of my shooting as the sun got brighter.

I believe they call that diffraction. The light is bending around your aperture blades, and I guess the lens you're using is Kosher... :-)
Shoot wide open or just a few steps down, and it should clear that up.

Great, now sell images as religious relics on Ebay and make your living!

The sun is too bright to appear any better. That's just how it is unless you use an extremely slow exposure.

Flat out awesome effect!

No need to post the huge photo...The center crop should have been sufficient. I have a large monitor, but not room size.

You probably are not stopped down too much - maybe F8-F11? If you stopped down more, the stars will become more pronounced and it will look like a proper 6-point star.

Come to think of it,, that was an Auto setting, i guess the camera changed the aperture setting.

New experience for me, used to shooting the sun with a 8 blade lens

@OldNoob

The picture you linked (...://farm3.staticflickr.com/2894/10907137273_859d137462_o.jpg)
will send some Android browsers crashing.

Better not to attach pictures that wide to PS postings.
I think Adam should make it impossible.
