In this post Julieanne Kost says "Post-merge, lens profiles don’t make any sense to apply to panoramas, so the feature is disabled."

Yet, in the current version (9.5) of ACR this is not the case and instead it is possible to select "Enable Lens Corrections" on a panorama stitched inside of ACR.

My question is: Does it make sense to select it, though? Or did the corrections already get applied during the stitching process and checking it would apply them twice? Or would they be applied incorrectly since it is not a single image?

Thank you!

If you enabled lens corrections (profile, vignetting) on a panorama result image, the corrections would not be applied correctly because the panorama is a different size and shape compared to a single image that the lens corrections do apply to.

Thank you, I will refrain from using lens corrections when dealing with panoramas.

But I actually have a follow-up question: When I create an HDR panorama by first merging all the exposures into HDRs and then merging the HDRs into a panorama, do I apply lens corrections before merging the different exposures into HDRs or not at all?

Hi Bernd,

It does not matter whether you apply the lens corrections before/after the HDR merge.  If you prefer to apply lens corrections, doing so either way will work (and produce the same results).  In concept, what really happens is that the lens corrections will be applied to the HDR-merged result.

When you stitch the HDR merges to a panorama, the lens corrections will automatically be applied before that pano is done.  (Thus, even if you forgot to turn on lens corrections on the individual HDR images prior to starting the pano merge, the lens corrections will still be applied.)

Hope this helps,
Eric

Thank you, this definitely helps! So basically, I don't need to worry about enabling lens corrections manually at all when creating a panorama, be it HDR or not.
