Silverfast 8.8. There is some pokiness when using masks and delving into History (in fairness it’s a lot of processing and will not freeze up so if you use them be patient), and has a few gotchas that can be overcome with experience and relying on the training tools, but so it goes with any advanced software. A built-in clone tool is slated to be added and should be available by the time you read this or will come as a software update soon thereafter.
