Last week a few readers said it would be nice to see a few examples of Chromatic Aberration and how it was removed. I didn’t include any with the last post because chromatic aberration is different in every image. But I thought this week as an expansion of last week’s blog post I would include a few samples just to show what to look for and what overdoing it looks like.
The full image shot with a 10.5 mm Nikkor Fisheye lens
With the fisheye as I said in the last post I am guaranteed to have some chromatic aberration, especially with the sun peaking over the mesa in the background. Hence for this image I selected the Highlight edges option as that was the only place that there was any chromatic aberration.
Chromatic Aberration (color fringing) on the highlight edges in the lower right corner.
Lower right hand corner with the Red/Cyan CA removed. Notice there is still some blue fringing that needs to be removed.
Lower right corner with the Blue/Yellow CA removed - and hence all of the CA is removed.
An example where I have taken the Blue/Yellow slider a little too far which creates a yellowish CA fringe.
So, there you have it. Normally an image will exhibit CA in both corners of the image but in this example the other corner is blue sky and hence there are no edges to exhibit CA.
That’s it for this session. See you next week.
Adios, Michael Clark
