Strange round spots in pic

[tejpartapgill]

I have a Nikon 7100. While taking a pic with flash during night towards sky, I am seeing a round spots in my pic towards the sky side. Anybody know why this is happening ? Is this dust or something else ?

Post an image so we can have a look? It could be sensor dust, it could be a reflection....

Have you checked your lens for water spots on the outer or inner element?
Or larger dust specs inside the lens?
have you take a photo of a blue sky and see if you have the same spots in the same location.

or, maybe it was aliens

They're Bokeh Dots.

Out-of-focus dust particles in the air.

Basically, a humongous air cleaner that's capable of filtering all the air in the scene.

Or, wait until there's no wind. Or just don't use the camera flash.

Ok why it is not happening with the landscape mode?

The flash probably isn't firing.

Don't know. but there were only a few slight circular blobs from above. maybe the dust or whatever is higher in the air.
Take test shots landscape and then start angling up until you get all the way up.
Then check the results against each other.

Do you have a "protection" filter on the lens?
It looks to me to be dust on a filter lit from light reflected off the objects the flash illuminated, and then reflected off the front lens element to light up the back side off dust on the filter.
