And what does it do
Every time you scan a book without book cradle, you put books under the section that is thinnest, so that both the left and right pages are almost at the same height.
Even though you scan with a so-called book rocker, even then there will be a difference between the left and right pages due to the thickness of the book.
If you use the “regular” crop method, you draw a rectangle around the left page and the right page. But there is not the same amount of text on each page; some pages are even blank.
Figure 6: For 1 page, the crop frame (green rectangle) of the left page is inside the content frame (red rectangle). This is 100% the case on no other page.

Figure 10:
The green left crop frame and the blue right crop frame are similar to each other. Although on some pages there is a photo or no text at all.

Even if you have a book of 1000 pages, you don’t have to check a single page for a wrong crop! (See fig.11: the result)
To get this amazing result, I used the Image Filters (fig.18) and I saved it in a workflow (Profile) for a next time, for similar books.
