• Organize and name layers. If you change a layer name in a Photoshop file after you have imported it into After Effects, After Effects retains the link to the original layer. However, if you delete a layer, After Effects is unable to find the original layer and lists it as Missing in the Project panel.

• Make sure that each layer has a unique name. This is not a requirement of the software, but it will help to keep you from becoming confused.

See also “Layer styles” on page 168 “Working with Photoshop and After Effects” on page 32 Preparing and importing Illustrator files

Before you save an Illustrator file for importing into After Effects, consider doing the following:

• Crop the image so that you are only saving the portion that you want to import into After Effects.

• To ensure that Illustrator files appear correctly in After Effects, select Create PDF Compatible File in the Illustrator Options dialog box.

• To copy paths between Illustrator and After Effects, make sure that the AICB and Preserve Paths options are selected in the Files & Clipboard section of the Illustrator Preferences dialog box. If you don’t select AICB in Illustrator, After Effects prompts you when you attempt to paste the path.

• To ensure that files rasterize most faithfully in After Effects, save your file in AI format instead of Illustrator 8.x or

9.x EPS format.

When you import an Illustrator file, After Effects makes all empty areas transparent by converting them into an alpha channel.

Note: When you’ve imported an Illustrator file, you can specify whether anti-aliasing is to be performed at higher quality or at higher speed. Select the footage item in the Project panel and choose File Interpret Footage Main, and click the More Options button at the bottom of the dialog box.

After Effects does not read embedded color profiles from Illustrator files. To ensure color fidelity, assign an input color profile to the Illustrator footage item that matches the color profile with which the Illustrator file was created.

See also “Interpret a footage item by assigning an input color profile” on page 245 “Copy a path from Illustrator, Photoshop, or Fireworks” on page 324

Cineon files are commonly used to transfer motion-picture film to a digital format. To preserve the full dynamic range of motion-picture film, Cineon files are stored using logarithmic 10-bpc color. However, After Effects internally uses 8-bpc, 16-bpc, or 32-bpc color, depending on the color bit depth of the project. Work with Cineon files in a 16- or 32-bpc project—by default, After Effects stretches the logarithmic values to the full range of values available.

In most cases, you should use color management features to automatically interpret the colors of Cineon footage.

(See “Working with Cineon footage items” on page 251.) You can, though, use the Cineon Settings dialog box to control the conversion manually.

Manual settings in the Cineon Settings dialog box:

Converted Black Point Specifies the black point used for the layer in After Effects.

Converted White Point Specifies the white point used for the layer in After Effects.

10 Bit Black Point Specifies the black level (minimum density) for converting a 10-bit Cineon layer.

10 Bit White Point Specifies the white level (maximum density) for converting a 10-bit Cineon layer.

Current Gamma Specifies the target gamma value.

Highlight Rolloff Specifies the rolloff value used to correct bright highlights. To get over range values when working in 32 bpc, set the value to 0.

Logarithmic Conversion Converts the Cineon sequence from log color space to the target gamma specified by the Current Gamma setting. When you’re ready to produce output from the Cineon file, it is important that you reverse the conversion. (To convert from logarithmic to linear, set Current Gamma to 1.) Units Specifies the units After Effects uses to display dialog values.

When you shoot JPEG files with your camera, the camera automatically processes the JPEG to enhance and compress the image. You generally have little control over how this processing occurs. Shooting camera raw images with your camera gives you greater control than shooting JPEG images, because camera raw does not lock you into processing done by your camera. You can still edit JPEG and TIFF images in Camera Raw, but you will be editing pixels that were already processed by the camera. Camera raw files always contain the original, unprocessed pixels from the camera.

To shoot camera raw images, you need to set your camera to save files in its own camera raw file format.

Note: The Photoshop Raw format (.raw) is a file format for transferring images between applications and computer platforms. Don’t confuse Photoshop raw with camera raw file formats.

Digital cameras capture and store camera raw data with a linear tone response curve (gamma 1.0). Both film and the human eye have a nonlinear, logarithmic response to light (gamma greater than 2). An unprocessed camera raw image viewed as a grayscale image would seem very dark, because what appears twice as bright to the photosensor and computer seems less than twice as bright to the human eye.

About Camera Raw Camera Raw software is included as a plug-in with Adobe After Effects and Adobe Photoshop, and also adds functionality to Adobe Bridge. Camera Raw gives each of these applications the ability to import and work with camera raw files. You can also use Camera Raw to work with JPEG and TIFF files.

You must have Photoshop or After Effects installed to open files in the Camera Raw dialog box from Adobe Bridge.

However, if Photoshop or After Effects is not installed, you can still preview the images and see their metadata in Adobe Bridge. If another application is associated with the image file type, it’s possible to open the file in that application from Adobe Bridge.

Using Adobe Bridge, you can apply, copy, and clear image settings, and you can see previews and metadata for camera raw files without opening them in the Camera Raw dialog box. The preview in Adobe Bridge is a JPEG image generated using the current image settings; the preview is not the raw camera data itself, which would appear as a very dark grayscale image.

Note: A caution icon appears in the thumbnails and preview image in the Camera Raw dialog box while the preview is generated from the camera raw image.

You can modify the default settings that Camera Raw uses for a particular model of camera. For each camera model, you can also modify the defaults for a particular ISO setting or a particular camera (by serial number). You can modify and save image settings as presets for use with other images.

When you use Camera Raw to make adjustments (including straightening and cropping) to a camera raw image, the image’s original camera raw data is preserved. The adjustments are stored for each image in either the Camera Raw database, as metadata embedded in the image file, or in a sidecar XMP file (a metadata file that accompanies a camera raw file). For more information, see “Specify where Camera Raw settings are stored” on page 104.

After you process and edit a camera raw file using the Camera Raw plug-in, an icon appears in the image thumbnail in Adobe Bridge.

If you open a camera raw file in Photoshop, you can save the image in other image formats, such as PSD, JPEG, Large Document Format (PSB), TIFF, Cineon, Photoshop Raw, PNG, or PBM. From the Camera Raw dialog box in Photoshop, you can save the processed files in Digital Negative (DNG), JPEG, TIFF, or Photoshop (PSD) formats.

Although Photoshop Camera Raw software can open and edit a camera raw image file, it cannot save an image in a camera raw format.

AFTER EFFECTS CS3 88 User Guide Note: In Photoshop, the Camera Raw dialog box is automatically suppressed when you use a batch of files for a web photo gallery, picture package, or contact sheet.

As new versions of Camera Raw become available, you can update this software by installing a new version of the plug-in. You can check for updates to Adobe software by choosing Help Updates.

For up-to-date documentation for Camera Raw, go to the Adobe website at www.adobe.com/go/learn_ps_camerarawhelp.

Different camera models save camera raw images in many different formats, and the data must be interpreted differently for these formats. Camera Raw includes profiles for many camera models, and it can interpret many camera raw formats.

Note: For a list of supported cameras and for more information about Camera Raw, see www.adobe.com/go/learn_ps_cameraraw.

About the Digital Negative (DNG) format The Digital Negative (DNG) format is a non-proprietary, publicly documented, and widely supported format for storing raw camera data. Hardware and software developers use DNG because it results in a flexible workflow for processing and archiving camera raw data. You may also use DNG as an intermediate format for storing images that were originally captured using a proprietary camera raw format.

Because DNG metadata is publicly documented, software readers such as Camera Raw do not need camera-specific knowledge to decode and process files created by a camera that supports DNG. If support for a proprietary format is discontinued, users may not be able to access images stored in that format, and the images may be lost forever.

Because DNG is publicly documented, it is far more likely that raw images stored as DNG files will be readable by software in the distant future, making DNG a safer choice for archival storage.

DNG is an extension of the TIFF 6.0 format and is compatible with the TIFF-EP standard. It is possible (but not required) for a DNG file to simultaneously comply with both the Digital Negative specification and the TIFF-EP standard.

Metadata for adjustments made to images stored as DNG files can be embedded in the DNG file itself instead of in a sidecar XMP file or in the Camera Raw database.

You can convert camera raw files to the DNG format by using the Adobe DNG Converter or the Camera Raw dialog box. For more information on the DNG format and DNG Converter, see www.adobe.com/go/learn_ps_dng.

Processing images with Camera Raw

1. Copy camera raw files to your hard disk, organize them, and (optionally) convert them to DNG.

Before you do any work on the images that your camera raw files represent, transfer them from the camera’s memory card, organize them, give them useful names, and otherwise prepare them for use. Use the Get Photos From Camera command in Adobe Bridge to accomplish these tasks automatically.

–  –  –

3. Adjust color.

Color adjustments include white balance, tone, and saturation. You can make most adjustments on the Basic tab, and then use controls on the other tabs to fine-tune the results. If you want Camera Raw to analyze your image and apply approximate tonal adjustments, click Auto on the Basic tab.

To apply the settings used for the previous image, or to apply the default settings for the camera model, camera, or ISO settings, choose the appropriate command from the Camera Raw Settings menu. (See “Apply saved Camera Raw settings” on page 105.) To see a video tutorial on adjusting images with Camera Raw, go to the Adobe website at www.adobe.com/go/vid0006.

To see a video tutorial on adjusting multiple images with Camera Raw, go to the Adobe website at www.adobe.com/go/vid0007.

4. Make other adjustments and image corrections.

Use other tools and controls in the Camera Raw dialog box to perform such tasks as sharpening the image, reducing noise, correcting for lens defects, and retouching.

5. (Optional) Save image settings as a preset or as default image settings.

To apply the same adjustments to other images later, save the settings as a preset. To save the adjustments as the defaults to be applied to all images from a specific camera model, a specific camera, or a specific ISO setting, save the image settings as the new Camera Raw defaults. (See “Save, reset, and load Camera Raw settings” on page 104.)

6. Set workflow options for Photoshop.

Set options to specify how images are saved from Camera Raw and how Photoshop should open them. You can access the Workflow Options settings by clicking the link beneath the image preview in the Camera Raw dialog box.

7. Save the image, or open it in Photoshop or After Effects.

When you finish adjusting the image in Camera Raw, you can apply the adjustments to the camera raw file, open the adjusted image in Photoshop or After Effects, save the adjusted image to another format, or cancel and discard adjustments. If you open the Camera Raw dialog box from After Effects or Photoshop, the Save and Done buttons are unavailable.

Save Applies the Camera Raw settings to the images and saves copies of them in JPEG, PSD, TIFF, or DNG format.

Press Alt (Windows) or Option (Mac OS) to suppress the Camera Raw Save Options dialog box and save the files using the last set of save options. (See “Save a camera raw image in another format” on page 93.) Open or OK Opens copies of the camera raw image files (with the Camera Raw settings applied) in Photoshop or After Effects. The original camera raw image file remains unaltered. Press Shift while clicking Open to open the raw file in Photoshop as a Smart Object. At any time, you can double-click the Smart Object layer that contains the raw file to adjust the Camera Raw settings.

Done Closes the Camera Raw dialog box and stores file settings either in the camera raw database file, in the sidecar XMP file, or in the DNG file.

Cancel Cancels the adjustments specified in the Camera Raw dialog box.

–  –  –

After Effects applies the settings for the first camera raw image in the sequence to all of the images in the sequence that do not have their own XMP sidecar files. After Effects does not check the Camera Raw database for image settings.

Note: Camera raw files are uncompressed. Their large size may increase rendering time.
