Half Moon

I took this picture tonight. Can anyone tell me what the blue is around the edge. I am not too familiar with PP and am only getting started.

Search color fringe. I took a photo of the moon and got the same effect.

Hello Steve,

The blue fringe is chromatic aberration. This happens when light rays do not focus correctly and is usually a sign of lower quality optics.

Hi Steve,

Less exposure will reduce it significantly.
It looks a little overexposed around the edge to me anyway.

Your EXIF:
Camera Maker: NIKON CORPORATION
Camera Model: NIKON D300S

Given the shutter speed and focal length, I assume it was a tripod shot, so go for f8 next time.

Yes, It was a tripod shot. Thanks for the comments. I just am intrigued by shooting the moon and getting the detail of the craters.
