The Mercury Graphics Engine of Photoshop Extended CS6 powers the blur gallery, the crop tool, 3D rendering, and the Lighting Effects Gallery. Image editing is now accelerated by the Mercury Graphics Engine, which leverages technology from the playback engine that drives the video-editing application Premiere Pro. With CS6 you can now search layers, and use layers to modify vector graphics (adding gradients, for instance) in the same ways you use layers with photographic imagery. Photoshop keeps track of each change you make to an image, allowing you to undo actions with ease. You can modify layer opacity and order, aiding in compositing tasks. Using layers allows you to make adjustments to images without modifying aspects of an original.

Photoshop Extended uses a powerful layer-based approach for image editing. Greatly expanded for this CS6 version, the software's tool set now includes a much larger array of 3D tools that let you create 3D artwork using in-context, on-canvas controls for extrusions, editing lights, and more. The Maximize Backwards Compatibility for Photoshop Files preference now correctly sets the state of the Maximize Compatibility checkbox in the Photoshop Format Options dialog box when you save a file as Photoshop (PSD) format.Adobe Photoshop Extended CS6 for Mac is the industry-standard tool for professional digital image editing. An issue that prevented Photoshop 6.0 from opening certain files containing layer effects and edited in Photoshop 7.0 has been fixed.

Photoshop no longer appears frozen when applying KPT3 filters. Metadata is better preserved in certain JPEG files. Picture Package no longer locks up when it encounters incorrect file types while using custom page layouts. Favorites now function correctly in the Open dialog box. Files made with Photoshop now work better with Microsoft Windows XP's automatic thumbnail generation. TIFF files with LZW compression are now written correctly.

The color of white areas in CMYK files saved as JPEG files no longer shifts. The total ink now defaults to 300% as it did in previous versions of Photoshop. If the color settings color management policy is set to 'Off,' Photoshop no longer asks to save changes unless other edits have been performed.

The most significant fixes in the 7.0.1 release include the following: Photoshop now saves alpha transparency data in Targa files in the same way it did in previous versions. The Adobe Photoshop 7.0.1 update fixes a number of problems discovered after Photoshop 7.0 was released.
