And what does it do
Every time you scan a book without a book cradle, you put books under the thinnest section so that the left and right pages are almost the same height.
Even when using a book rocker, the left and right pages will inevitably have different heights due to the book’s thickness. This highlights the need for alternative methods when scanning without a book cradle.
If you use the “regular” crop method, you draw a rectangle around the left and right pages. However, there is not the same amount of text on each page; some pages are even blank.
Figure 6: For 1 page, the left page’s crop frame (green rectangle) 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, 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 the wrong crop! (See fig.11: the result)
To get this amazing result, I used the Image Filters (fig.18) and saved it in a workflow (Profile) for future use on similar books.
