I am using a Nikon AF-P DX NIKKOR 70-300 mm f/4.5-6.3G ED VR Lens with mt D3300 camera, and processing the NEF with RawTherapee software on Linux. On zooming in the image, I find chromatic aberrations -- blue lines appearing on long contours. [A sample photo is attached]

 

Is there a way to solve the problem?

A few things to try:

1. Ensure the focus is accurate

2. Stop down by an extra stop or two

3. Reduce the exposure slightly

 

As this looks like a pretty tight crop, the whole image may not be quite as bad as it may appear.  Software should be able to fix most of the aberrations for you.

Thanks Adam. I shall try that out.

Yes, the overall image is not all that bad. The effect is not visible there.

Regarding software, I am using RawTherapee. Though there is a feature for correcting chromatic aberration, it is not so effective in these images.
