First remove CA then stack with Zerene or vice versa?

Post by Adalbert »

Hello everybody,
Actually I only would like to know when the CA should be removed:
1.) Before stacking (e.g. during the conversion from RAW into the TIFF by LR)
2.) After stacking (LR or PS)
Does the Zerene like/need the pictures with CA?
If you removed the CA first, would Zerene miss any information from the pictures?

I recommend to remove CA during raw conversion, because that is usually when the best information is available to do that.

Zerene Stacker does not use the CA for anything, so nothing will be lost by removing it during raw conversion.

Depending on the stack, optics, and raw conversion software, CA may not be completely removed from the source images. If that happens, you might need to remove CA after stacking also. But again, nothing should be lost by attempting to remove CA during raw conversion, even if it doesn't quite finish the job.

Hello Rik,
Many thanks! So, I will add that to my workflow.
CA will be removed by LR during the conversion of the CR2 into the TIFF.
