Often I have found that I want to apply perspective correction to multiple files at once using the Upright feature in Camera Raw. But depending on the results I want to achieve, it’s best to know that there are two different ways of accomplishing this. Note: For both methods, it is recommended that you first enable Lens Profile Corrections and Remove Chromatic Aberration using the Lens Corrections panel in Camera Raw.
METHOD ONE - in the first situation, you might have a series of unrelated images that all need to have their own set of perspective corrections made to them. In this case, the easiest way to apply Upright would be to:
• Select all of the desired files in Camera Raw. Then in the Lens Correction panel, in the Manual sub-panel (where the Upright controls are) click the desired Upright mode (Auto, Level, Vertical, or Full) in order to apply the perspective correction to all selected files.
• With this method, each image is analyzed individually and the perspective corrected.
Note: if you prefer not to select all of the files first (or have additional settings in other panels that you want to synchronize to multiple selected images), you can select the first file and apply the desired changes including the Upright mode. Then, add the other images to your selection and click the Synchronize button. In the Synchronize dialog, check the settings you want, plus Transform. And, if you do this often, you may want to consider creating a preset to apply an Upright transformation mode.
METHOD TWO – in the second situation, you might have a series of related images – such as a sequence of bracketed exposures or a set of time lapse images for which you need the same exact numeric perspective corrections made to each image. In this scenario, you don’t want to run the upright analysis on each individual image because Upright is likely to return a slightly different result on each of the images in the selection. Instead, what you want to do is have the upright analysis be performed on one of the images, and then have the result of that analysis (the numeric transformation) synchronized across the other images in the set.
In order to do this, select the first image of the series (in this case one of several exposures necessary to create a single HDR image) and apply the desired Upright transformation option.
Then, add the additional images to your selection and, in the Lens Correction panel, in the Manual sub-panel, click the Sync Results hyperlink.
With multiple images selected, Camera Raw will copy Upright’s numerical transformations from the primary image to the other selected images.
