She was positioned at one time to mark the hazards at the entrance to the Humber Estuary on England's east coast.

@ant_pruitt - There is a sort of bloom, or halo, around the lamp in this image. it is less obvious in the full size (follow the link) and more so in thumbnails (ditto)

I have noticed this along rooflines too, where they "meet the sky".

Is this an artifact of JPG compression? if so, how does the amount of compression affect it?

Or is it something the camera does before compression?

@ant_pruitt @BobHarvey That looks like the effects of over-aggressive HDR tone-mapping. Are you processing your photos in any way? Or, are you pulling these directly out of your camera?

It's not one of mine.

I haven't noticed this sort of fringing on mine since I started using a mirrorless. & Saving raw. Which is what made me wonder if it is a camera or compression artifact.

The culture on the web site is to do little or no processing. Most people post straight from the camera.

@BobHarvey @ant_pruitt Sorry, I didn’t realize they were not your images. This doesn’t look like a compression artifact. It appears that the author has tried to restore a blown-out sky. The white around the edges is the exposure of the bright sky without compensation. The rest of the sky has been darkened to bring back the blue and some other details. There are techniques that would reduce or eliminate these halos and still allow proper exposure for the sky and foreground.
