How to remove weird sun glare artifacts?

[daweakling]

Does anyone have any advice on how to remove these types of artifacts in photos? It seems to be some sort of sun glare. I tried looking into it but only found methods of removing lens glare but not this type of thing. What would this be even called?

 

The only way I found to fix this is to manually touch up details and erase the artifacts in Photoshop, but is there an easier method? I was using a polarizer filter to remove reflections in windows, but not sure if that would cause this.

That's purple fringing, results from poor quality lens. I doubt the polarizer is the culprit but you could compare with/without, if it's the same it's just the lens/camera.

 

Lightroom has a "Defringe" setting, this was by moving just one slider a bit.

It looks like longitudinal chromatic aberrations or spherochromatism. That type is caused by the lens focusing different colours of light at slightly different distances, usually going purple in one direction, green in the other. The hardware fix is buy a better lens but there are essentially no perfect lenses, so it is a question of how much there is. It might be mitigated to an extent by stopping down effectively making the focus converge more, but highlights like those can still overpower it. Software fix is to selectively remove purple when it happens.

 

Adding a filter could influence it since it does change the optical path of the system, but not to a significant degree.

Thanks for the explanations and tips to remove it. I am not using a very high-end lens. It's only a ~$100 35mm f1.8 Nikon lens.
