I just noticed when using ACR 8.1 that, when applying a "previous conversion" that includes a vertical manual lens transform, no vertical correction is made to the new file, but the new-file horizontal transform is made the negative of the old-file's vertical. Thus, to be specific, if one had made a vertical transform of, say, -8 in the old file and then applied "previous conversion" to a new file, the new file's vertical would remain zero, but the horizontal would be +8.
I'm not sure if it makes any difference, but I'm using ACR 8.1 with a licensed copy of CS6, not with a CC version. I'm using MacOSX 10.8.4.
Has anyone else noticed this or can someone try this to see if they find the same issue?
I am using ACR 8.1 with CS6 on a Windows 7 64Bit Professional computer and do not see this problem. I have all of the latest Photoshop CS6 updates installed.
Whether the horizontal or vertical transform is applied when applying Previous Conversion will depend on the orientation of the images in question. Are both the images (the previous one, and the current one) the same orientation?
Yes, Eric, I do believe that was the case now that you mention it. I've just checked again with images of the same orientation, and it does indeed appear to be working correctly.
Thanks -- that seems to resolve the issue.
