Artlandia has released version 3 of Artlandia SymmetryShop, a Photoshop plug-in for professional pattern design. The company says that SymmetryShop 3 provides many new features and simplifies the design workflow by making the plug-in functionality available as a floating Photoshop panel.

SymmetryShop automatically creates the seventeen mathematical types of symmetric patterns as well as drop and diamond patterns, grids, gradations, sateens, and other standard repeat systems. The plug-in keeps the image source available for unlimited iterations and refinements throughout any number of Photoshop sessions. The new version makes this core functionality more easily accessible and adds new important features.

As a key improvement to previous versions, SymmetryShop 3 is available as a floating panel (similar to the Layers, Channels, Paths, and other standard Photoshop panels) and no longer requires the user to open a special dialog in order to create a pattern or change its properties.

In addition, SymmetryShop 3 supports the Large Document Format and at the same time improves performance by letting the user reduce the image size of a pattern on the fly. At the end of the creative process, the user can rebuild the pattern at full size and quality by pressing a button.

The new SymmetryShop panel also adds convenience buttons that streamline a typical pattern design workflow. These include targeting the seed (motif) layer, selecting the control path, visualizing the area exported as a pattern preset, previewing the exported pattern, and other functions that used to require multiple steps.

Artlandia SymmetryShop 3 costs $315 (around £210) and is available for Mac OS X and Windows. Photoshop CS4 is required to use the floating panel and most new features. Upgrades cost $75 (£50).
