does CA (Chromatic Aberration) even matter anymore ?

Just curious quite a number of people/reviewers complain about CA, but when you process RAW files with Nikon Capture, it automatically removes (when turned on) CA and actually makes corrections for it resulting in a sharper image. I have tested this a few times with a JPEG vs. a RAW file and the results are pretty amazing. Photoshop CS3 Camera RAW has a CA filter, but unfortunately it only removes the color fringing. I know the D300 and D3 have this built in now.

I took a look at the link, and it is for the Apple version of Capture. Does anyone know if auto CA adjustments can be turned on on the PC version of Capture 1.3?

Thanks!

It's already there under "Raw Adjustments".


The software (NX, CS, and in-camera) goes a long way toward correcting CA, but there's no substitution for a good lens. Find an image with a good amount of CA and do a before and after set with NX 1.3~2. Yup, CA gets reduced but parts of the image sometimes also looks a little softer after the CA correction.

Does looking at CA matter anymore? Just like an unsharp-mask isn't a solution for a soft lens, CA-correction isn't a solution for a lens with bad CA. Both help, but there's no substitution for quality.

Yep
CA auto mode is available for both Mac and PC on Capture NX.

If you had a D300 and shot RAW (I made a bunch of tests)... its very noticable how the photos clean up with Capture NX and CA set to auto.

CA still robs the picture of some sharpness, and correcting for it won't bring that sharpness back. Also, bokeh CAs (longitudinal CAs) can't be corrected.

I think that CA does matter. The less CA there is in the first place, the more effective the software will be at removing it and retaining detail afterwards.

Still, I find with the latest bodies and recent pro glass, I've not seen a hint of CA in my NEFs run through CNX1.3.3/2.0
