Enable Middle Eastern features

To reveal Middle Eastern type options in the Photoshop interface, do the following:

1. Choose Edit > Preferences > Type (Windows) or Photoshop > Preferences > Type (Mac OS).

2. In the Choose Text Engine Options section, select Middle Eastern.

3. Click OK, and restart Photoshop.

4. Choose Type > Language Options > Middle Eastern features.

Text direction

To create content in Arabic and Hebrew, enable right-to-left (RTL) text direction. While RTL is the default direction of text, many documents also

include left-to-right (LTR) text. You can seamlessly switch between the two directions.

Select the paragraph direction from the Paragraph panel.

Paragraph direction selection (InDesign panel shown)

Digit Types

When you are working in Arabic or Hebrew, you can select the type of digits you want to use. You can choose between Arabic, Hindi, and Farsi.

By default, in Arabic versions of Photoshop, Hindi digits are auto-selected; in Hebrew versions, Arabic digits are selected. However, you can

manually change digit types if necessary:

1. Select the digits in the text.

2. In the Character panel, use the Digits menu to select the appropriate font.

Digit type selection (InDesign panel shown)

Legacy font support

Fonts that have been traditionally used (for example, AXT fonts) can continue to be used in this release of the software. However, it is

recommended that newer Open Type fonts be used for text-based elements.

Missing Glyph Protection (Edit > Preferences > Advanced Type) is enabled by default. Text is handled automatically, where glyphs are not

available in the font you are using.

Default fonts

When you install a Middle Eastern or North African version, the default typing font is set to the installation-specific language, by default. For

example, if you have installed the English/Arabic-enabled version, the default typing font is set to Adobe Arabic. Similarly, if you have installed the

English/Hebrew-enabled version, the default typing font is set to Adobe Hebrew (or Myriad Hebrew in Photoshop).

Automatic Kashida insertion

In Arabic, text is justified by adding Kashidas. Kashidas are added to arabic characters to lengthen them. Whitespace is not modified. Use

automatic Kashida insertion to justify paragraphs of arabic text.

Select the paragraph, and at the lower-right of the Paragraph panel, choose an option from the Insert Kashidas pop-up menu: None, Short,

Medium, Long, or Stylistic.

Note: Kashidas are inserted only in paragraphs with fully justified margins.

To apply Kashidas to a group of characters, select the characters in the document, and then choose Type > Language Options > Kashidas.

Ligatures (OpenType fonts)

With some OpenType fonts, you can automatically apply ligatures to character pairs in Arabic and Hebrew. Ligatures are typographic replacement

characters for certain letter pairs.

1. Select text.

2. In the Character panel, above the language and anti-aliasing menus, click the Standard or Discretionary Ligatures icon.

Discretionary ligatures provide more ornate options that some fonts support.

Hyphenation

Sentences that have more words that can fit into one line of text automatically wrap into the next line. The type of text justification when wrapping

occurs sometimes causes unnecessary spaces to appear in the line that are not aesthetically pleasing or linguistically correct. Hyphenation

enables you to split the word at the end of a line, using a hyphen. This fragmentation causes the sentence to wrap into the next line in a better

way.

Mixed text: The Kashida insertion feature affects how hyphenation occurs in mixed text. When enabled, Kashidas are inserted where applicable,

and non-Arabic text is not hyphenated. When the Kashida feature is disabled, only non-Arabic text is considered for hyphenation.

Hebrew text: Hyphenation is allowed. To enable hyphenation and customize settings, choose Paragraph panel > Panel menu > Hyphenation

Settings.

enhancements are available in the Creative Cloud version of Photoshop, see the Adobe Creative Cloud Only section of What's New in CS6.

From an expert: 3D in CS6 - a video tour

Updated 3D features for Creative Cloud only

In addition to the 3D features in Photoshop CS6 described in the following sections, there are these additional 3D enhancements in the Creative

Cloud version:

32-bit color pickers can now be used when specifying colors for materials, lines, surfaces, or lights in the Properties panel.

Normal maps can be generated from Diffuse maps. In the 3D panel, select the 3D object you want to affect and then, click the Filter By

Materials icon in the top area of the panel. Then, in the Properties panel, click the folder icon next to Normal: and choose Generate Normals

From Diffuse from the menu.

If you pause a rendering and make one or more selections, resuming the rendering will be applied to the selections. Resuming a rendering

also works even after saving your document as a PSD.

Cross Section now works with reflective surfaces and other surface styles such as Constant, Cartoon, and Sketch.

By default, an Image-Based Light (IBL) is added your 3D environment. Adobe offers other IBLs for download from Adobe® Photoshop®

Extended 3D Content.

You can change the Ray Trace rendering tile size from its default, which is set based on how many cores are in your computer. Choose Edit

> Preferences > 3D (Windows) or Photoshop > Preferences > 3D (Mac OS) and then, choose a size from the Render Tile Size menu in the

Ray Tracer section of the Preferences dialog box.

During rendering, both the time remaining and percentage rendered are displayed in the Status Bar at the bottom of the document window.

Photoshop now offers better OpenGL shadows. To specify the shadow quality that works best with your computer, choose Edit >

Preferences > 3D (Windows) or Photoshop > Preferences > 3D (Mac OS). Then, choose an option from the Shadow Quality menu in the

Interactive Rendering section of the Preferences dialog box.

To the top

In the streamlined 3D panel, select specific elements you want to edit:

1. At the top of the 3D panel, select Scene , Meshes , Materials , or Lights .

2. Select an individual element (such as Current View in the Scene section). Or select multiple elements to apply uniform properties.

3. Adjust settings in the Properties panel, or drag in the document window. (If you drag a specific object or light, the 3D panel then selects that

element.)

Note: To add new lights, click the document icon

at the bottom of the Scene and Lights sections. Or click the panel menu to save and load

groups of lights as a preset.

Properties panel provides contextual settings

After you select individual elements in the 3D panel or document window, the Properties panel displays related settings. When you finish adjusting,

click the Render icon

at the bottom of the panel.

Note: Click the Coordinates icon at the top of the panel to enter precise numerical locations for objects, cameras, and lights. To quickly cycle

between properties and coordinates, press the V key.

Environment settings include global ambient and image-based lights, and ground plane shadows and reflections.

Scene settings include render presets such as Bounding Box and Wireframe, and custom render options for cross-sections, surfaces, and points.

Camera settings include field of view (FOV), depth of field, and stereo options for anaglyph, lenticular, or side-by-side viewing.

Mesh settings let you catch and cast shadows, adjust 3D extrusions, and edit source text and paths.

Note: To hide an object, but retain its shadows for compositing with 2D images, select Invisible.

Materials settings include texture and bump map settings such as the new Roughness option.

Light settings let you choose from infinite, spot, and point types, and adjust color, intensity, and shadows.

Move tool consolidates object and camera adjustments

The Move tool lets you adjust the placement of objects and camera:

In the options bar, choose between Rotate , Roll , Drag , Slide , and Scale modes.

To quickly cycle through these modes, press Shift + V.

To quickly switch between camera and Environment controls, click away from 3D objects.

Note: In the document window, a gold document border indicates camera control, a blue border Environment control, a green border Scene

control, and no border Mesh control.

On-image controls directly edit elements

With on-image controls, you can often edit an entire 3D scene without accessing any workspace panels. To maximize your view, press the F key

to cycle between full screen and standard screen modes.

In the document window, you can directly interact with the following elements:

Scene, Mesh, and Light settings To quickly access Scene properties in the document window, right-click the canvas away from 3D objects. Or
