To convert a number of RAW files efficiently with Photoshop CSi you must create your own Photoshop action. This action should open a file in ACR, apply all settings for the ACR workflow (selecting output Resolution, Depth, color Space, Size, ...) start the conversion, make the setting for the target format, and finally save the file using the appropriate (preferred) image mode. Important in file saving is selecting an output file format and various settings for that specific file format. (The following is brief description how to create such an action. For more details, please refer to the Photoshop Help system).

How to create an action in Photoshop

Photoshop actions are very useful tools to do repetitive tasks. Creating a new action may be as easy as just recording the different Photoshop steps in your task. Thus, an action is a sequence of steps (such as opening a file or setting a new image mode) in Photoshop.

To create your new action, activate the action panel (Window rActions).

Before starting, have a look at the basic recording tools in the action button bar: □ C _i ft Their functions are (from the left to right):

Ol c

J Stop recording

Record button: shows "red" if Photoshop is recording an action and "green" when the recording is stopped.

Replay action

Create a new action set

J Create a new action * Delete action or action step

To create an action for batch processing RAW files, first create a new action SET by clicking . Enter a descriptive name for this action set:

^ew Set

x]

Name: My_Batrh_converaon

Cancel

Select the new action set in the action panel and click to create a new action. This starts recording the following Photoshop steps. But, first a dialog appears, asking for a name for the new action. Lets us call it "16-bit RAW conversion".

The next steps to be recorded, done in Photoshop, are:

► Open a RAW file (File rOpen). It doesn't matter which file you open because its name will later on be replaced by the source selection).

► When Adobe Camera Raw appears, set all Work-flow Options you want to use for your batch conversion. From the ACR Settings menu, select the appropriate conversion settings set you plan to use in your batch.

► Click Open to start the conversion. The converted image will be opened in Photoshop.

► In Photoshop set the image mode you desire and add prototype adjustment layers (this, only useful, if you prepare your images for individual image corrections after the batch conversion is complete).

► Call up "Save as" (FilerSave as), select the appropriate file format (e. g. TIFF) and explicitly set all options and modes for your intended file format. The file name you give here will be overwritten when the actual batch processing is performed.

► Close the Save dialog by clicking OK.

► Close the image window in Photoshop.

Click to stop recording and thus finishing your action.Take a glimpse of the steps in your action by clicking at ^ of your particular action in the action panel. You will see all steps and values chosen. Photoshop allows adding more steps, deleting or replacing steps. All this is well documented when you call up Photoshop Help.

You should now save your action set (select action panel, right-click on » and select Save Actions).

To start batch processing with Photoshop, select File ^Automate r Batch.

There are four sections in this dialog:

► Play for selecting the action-set and action.

► Source to select the source files.

► Destination to specify where the processed (converted) files should go.

► Errors-Handling

Section "Play" ► First, select the action set. An action set is a collection of different actions grouped into a set. To be listed in this pulldown menu, it should reside in the Photoshop default script folder.

You may, however, load additional scripts in Photoshop: Activate the action panel (Window rAction). In that panel choose Load Actions from the i drop-down menu. From the Set menu of the Batch dialog select the specific action you plan to use to process your source files.

Section "Source" ► In the source section is specified which files to process and how the processing should be done. Various source selections are available: For this RAW conversion, only Folder or Bridge (or File browser with CSi) is of interest. Selecting Bridge processes those files selected in Bridge (or the Photoshop browser). Or, if you select Folder, all files in that folder (and optionally all files in its subfolders) are processed. In this case, you must select the source file folder by clicking the Choose button. In either case, we strongly recommend the following settings:

1 Figure 8-3: Suppress Open and Warning dialogs

Override Action "Open" Commands will suppress the open dialog box as each source file is processed - it, nevertheless, will open each individual file. If you do not check this button, only that file will be opened which was in use when the batch script was recorded.

"Include All Subfolders" is optional and will do a recursive processing of all source subfolders, as well. We rarely use this option.

Suppress File Open Options Dialog suppresses the file Open dialog when opening individual source files.

Suppress Color Profile Warning suppresses a pop-up of the warning dialog if there is a mismatch of color profile of the converted file and current working space of Photoshop.

Section "Destination" ► Similarly to the source section, you specify your file destinations. They may either be written to the same folder as the source files or to a different destination folder (which you are asked to select by clicking Choose).

Section "Errors" ► If an error occurs while processing the files, the processing may either stop (useful when debugging your scripts) or the error may be logged to a dedicated log file while processing continues with the next source file. The second option is preferable in the final, well-tested script.

Batch conversion using Bridge

Using CS2 and Bridge for a standard batch RAW conversion, it is unnecessary to build a Photoshop action. There is a simpler way:

► Select the files you want to convert within Bridge.

► Call up Tools r Photoshop rImageporcessor. This brings up this dialog box:

Image Processor

You probably already know the scheme:

© Open the first (additional) image in ACR and do the conversion settings to be applied to all selected files (1). If you don't use this option, current settings of the individual selected files are used instead.

2 Select the destination for converted RAW files.

2 Select a file format for converted files. You may generate JPEGs, as well as, PSDs or TIFFs - all simultaneously. You may even resize the (converted) images.

4 You may select an additional Photoshop action to be applied to the converted file. The default action offers several different £ workspaces.

E You should always include the ICC profile of your destination

^ color workspace.

You may Save the current settings of this dialog box or may Load settings previously saved.

Clicking Run starts the conversion. If you selected the Open first & image to apply settings (see area 1 of figure 8-4), ACR pops-up the

Open dialog where you may select a RAW file. This RAW file will be £ open in ACR, and you may set up various ACR settings for image o optimization. Clicking Open in ACR starts the conversion using the c selected ACR settings for the selected file of the Open dialog as is well as the previous files selected in Bridge.

£ The pictures will eventually display in Photoshop, yet no actions are cD required, and images are saved automatically.

Some Predefined scripts with Photoshop CS2 and Bridge

Photoshop CS2 ships with an assortment of preconfigured scripts to do batch conversion. If the scripts are to your liking (test them!), all you need to do is select the files to be converted in Bridge and call up the chosen conversion-function.

To select batch-conversion in Bridge, select Tools rPhotoshop r Convert to. You may select one of the preconfigured destination file formats like JPEG, PDF, TIFF, ...

Simple Photoshop CS2 Batch Conversion Using Bridge

When using Bridge, you may proceed very similarly:

1. Select the files you want to convert within Bridge.

2. Shift-douple-click the previous file selected. This brings up ACR in the film-strip-mode.

3. Select the file you want to use as the reference for your settings. Do all corrections you wish to apply to this and the other images.

4. Now, select all files of the film strip (using the shift key) or click the Select All button (upper left corner).

5. The ACR Save button will change to "Save n images".

6. Clicking Synchronize will apply settings to all selected files.

7. Click Save n images. The dialog box of figure 8-7 pops up.

1 Figure 8-7

8. Clicking Save starts the actual batch conversion of selected files. ACR registers the status of the processing at the lower right corner of the ACR window, just above the Save button.
