Batch rotate an arbitrary amount in LrC (eg. 1-2%?)

[Patrick Kilburn]

Hello,

I imported 600 (raw) frames from a timelapse and realized after the fact that my horizon was off by a measly 1 degree. I know how to edit an image and create a preset to apply general edits (already done), but I can't seem to find a way to batch rotate 1 degree. Only 90 L or R... Any thoughts??

The Crop Tool allows you to rotate images by 1 or 2 degrees, or however many degrees you want. Now I haven't tried it, but if you select all the files of interest, then go into the Develop Module and click on AutoSync and do the rotation in the crop tool, they should all rotate by the same amount. Remember to turn off AutoSync when finished.

Thanks very much - worked like a charm!! Autosync turned back off 😉

Just to clarify: using the Crop tool and Autosync / Sync, images will be rotated "TO" a common crop angle.

But if one image was currently set to -5 degrees, and another was set to +3 degrees, then syncing +2 degrees onto both would mean a different new amount and direction of change, for each one.

Where starting angles differ, you may want to rotate these all "BY" a certain further number of degrees.

For doing that, in the Transform panel, is a manual Rotate slider. This acts cumulatively onto whatever the crop panel may be variously doing already, on each image.

Transform has got a Constrain Crop checkbox, which will auto-crop each image on the fly as needed (keeping the aspect ratio shape of its crop the same) to ensure its corners do not open up any white gaps. The Crop tool always constrains itself to the edges of the overall picture regardless: it does not have such a checkbox.
