Akvis Software has released SmartMask 4.5 (http://akvis.com/en/smartmask/), an update of the image selection and masking plug-in for the Mac and Windows platforms. The upgrade is compatible with Adobe Photoshop CC.
SmartMask is a masking tool designed to save time on complex selections. With the app, there are two pencils, red and blue. Draw a line with the blue pencil inside the object being selected (for example, yourself in a group photo) and then outline the same object with the red pencil to define the areas that should be cut out. The selection algorithm analyzes the image and your drawing, and creates the selection you want. Akvis SmartMask features three selection modes are tailored to different types of selection: Sharp, Soft, and Complex.
On the Mac platform, SmartMask requires Mac OS X 10.4 or higher. The product sells for $90, downloadable from http://akvis.com. The functionality of the program depends on the license type. During the trial period you can try all options and choose the license you need.
