It is certainly not free but is very good. I have version 3 Pro but I use for visual only. In version 4 the developer split visual and imaging. Imaging has been released but visual is pending. There are different upgrade price options if you buy 3 now than if you bought but a couple of years ago. See Skyhound website for details.
