Unfold it in a meeting or classroom, and place a book, document, photo, or pretty much anything else on the large 17 x 13″ shooting area. Set the overhead camera and two gooseneck lamps just right, zoom in by up to 20x (which is enough to clearly see some of the tiniest details), and project the image live on an HDTV, projector, or other display.
Using the included software on your laptop or desktop (Mac/Windows), annotate the image to point out specific details, and/or add various effects, such as picture-in-picture or mask, to highlight details, make comparisons, and much, much more. Alternatively, you can make annotations without a computer/software by plugging a mouse directly into a USB port on the side and using the mouse.
The PS752 allows you to save up to 240 JPEG images to built-in memory. But it also supports up to 4TB USB flash drives via the USB port on the side (the one that accepts the mouse for annotations). So you can store images as well as videos to a flash drive, sold separately, as well as to your computer via the included software.
