The Multi-Crop feature greatly improves productivity as it allows multiple images with a specific crop each to be automatically created from a single capture.
This feature is particularly valuable with high-volume archives where multiple crops can be made in the same position, such as when scanning film (particularly small format), or when digitizing postcards or similar. With books, for example, both pages can be cropped into two separate images, leaving the original capture complete with an Object Level Target (OLT).
The resolution of the original capture will obviously dictate the number and size of crops, but the feature can greatly speed up workflow. Note that this feature needed a script to run on earlier versions, but this is no longer the case.
