Hi,

I took these pictures on 1/4/2017 with different speed settings - 1/13 and 1/20 with exact A and ISO settings. The one on the left has no star/cross along the edge but the one on the right has a lot. I am wondering if it was the speed or something else. Please help and comments. Thanks.

What camera and lens? Speed too slow and ISO too high. Here's one from 1/1/2017 at ISO 200, 1/100, f/5.6:

Here's a bit about the star effect:

Fred, thanks very much for the link that describes the star effect. I use the Olympus SH1 camera.

Just to give you a comparison on shutter and ISO, here is mine from January 2 at 1/200 shutter speed and ISO 400, f/6.5. Yes, your shutter to slow and your ISO too high.

Here one from the other night.

None of the answers address the ops question - why the star on 1/20 seconds shot and not on 1/13.

Yes the image is overexposed.

The star effect can be caused by the narrow aperture - yours seems to be 6.9...a bit of a strange number for aperature..can you check that?

I took photos of a motorcycle @ f22 and the reflections from the chrome had the star effect similar to this. You may want to check meta data again for aperture settings. I agree with zigipha, 6.9 is an unusual aperture setting.

I see from the camera specs that f-6.9 is the smallest aperture that the SH1 compact camera has, which feeds back into the link and its mention of aperture and starring. Perhaps the first shot has no starring because it is much more blurred, perhaps due to the slower shutter speed.

Others here may have more specific suggestions.

You are way, way over exposed. The moon light is the same as noon sun light on earth. I always check my captures and adjust as needed.

Hi all, thanks for your comments and input. I agree that the pictures are over exposed. Are you saying that if the exposure was correct, then there is no star?

And the aperture not to narrow...etc.

You can get that star effect from lights by going to F22 or higher
