I have a series of images (many, many images) that were taken with slightly uneven lighting:
I also have an image of the blank white background under the same lighting:
I would like to use the blank image as a map to even out all the other images' background. I know this is commonly done in book scanning and this great post shows how to do it in Photoshop with layers.
But my images are RAW and I'd like to batch process without saving a ton of intermediate versions. Is it possible to do this in Lightroom?
