Version 2 sweeps away these objections and adds convenient new tools as well, such as Brush and Eraser tools and an Auto Outside Object command for automatically generating an outside selection after you have outlined the inside selection. The single level of undo and the lack of CMYK support were also annoying limitations in the standalone application. The changes you make in KnockOut 2 are immediately applied to the working layer of your document. There are two advantages to the plug-in route: First, the program uses less memory and second, you don’t have to export the file and load it into Photoshop. It installs as a Photoshop plug-in and can be used by any program that supports Photoshop-compatible extras.

So the first thing you’ll notice about version 2 is that it’s no longer a standalone app.

It was a standalone application that hogged your system memory - it ate up a whopping 348MB of my 512MB system - which meant you couldn’t keep Photoshop open while you were working in KnockOut. Figure 1: Two selections from the same image: The image on the left was generated by Photoshop’s Extract Command the one of the right by KnockOut 2.Įarlier versions of KnockOut were clumsy to use.
