Blue outline on bright whiteness

I get it all the time on my photographs. Can someone explain what it is exactly and how to avoid it?

CA = Chromatic Aberration

Chromatic aberration - Wikipedia, the free encyclopedia

Could also be in-camera sharpening and/or compression artifacts. Kyle, can you post a picture that shows it?

Pixel bleed - where there is too much light compared to surrounding pixels and (electronically) some spillage occurs.

Or it could be a chromatic aberration issue as per above.

PS. Really could do with a still image to view.

Or maybe there was a bluebird streaking through the frame:<)

Anyhow, as others are saying, could be a lot of things and without seeing it it's awfully hard to know what is causing it.

Did your camera cost more or less than $29.95? ;-)
