image and is calculated based on the RGB output space that has been selected in the Workflow options. As you carry out the Basic panel Exposure and Blacks adjustments, the shadow and highlight triangles in the histogram display indicate the shadow and highlight clipping. As either of these get clipped, the triangles will light up with the color of the channel, or channels, that are about to be clipped, and if you click on them, they display a color overlay (blue for the shadows, red for the highlights) to indicate which areas in the image are currently being clipped.

At the bottom are the Workflow options, which when clicked will open the Workflow Options dialog shown in Figure 3.12 . The destination color space should ideally match the RGB workspace setting established in the Photoshop color settings, and I would suggest setting the bit depth to 16-bits per channel, as this ensures that the image bit depth integrity is maintained when the image is opened in Photoshop. The file size setting lets you open images using smaller or larger pixel dimensions than the default capture file size (these size options are indicated by + or − signs) and the Resolution field lets you set the file resolution in pixels per inch or per centimeter, but note that the value selected has no impact on the actual pixel dimensions of the image.

Figure 3.12 The workflow options let you set the color space and pixel dimensions, plus other options (see Figure 3.11 caption).

The Toggle Full screen mode button ( ) can be used to expand the Camera Raw dialog to fill the whole screen, which can make Camera Raw editing easier when you have a bigger preview area to work with. Click this button again to restore the previous Camera Raw window size view.

General controls for multiple file opening

If you have more than one photo selected in Bridge, you can open these all up via Camera Raw at once. If you refer back to Figure 3.10 , you can see a summary of the file opening behavior, which is basically as follows. If you double-click, or use File Open ( ), this opens the multiple image Camera Raw dialog hosted via Photoshop (as shown in Figure 3.14 ) and if you choose File Open in Camera Raw…, or , this opens the multiple image Camera Raw dialog hosted via Bridge.

Figure 3.14 Here is a view of the Camera Raw dialog, in the multiple file open mode, hosted in Photoshop (you can tell because the Open Images button is highlighted here). This screen shot shows the filmstrip of opened images on the left where all four of the opened images are currently selected and the top image (highlighted with the blue border) is the one that is ‘most selected’ and displayed in the preview area. Camera Raw adjustments can be applied to the selected photos one at a time, or synchronized with each other, by clicking on the Synchronize settings button. This opens the Synchronize dialog shown in Figure 3.15 . Note that if you hold down the key as you do so, this will bypass the Synchronize dialog options and synchronize everything.

The multiple image dialog contains a filmstrip of the selected images running down the left-hand side of the dialog and you can select individual images by clicking on the thumbnails in the filmstrip, or use the Select All button to select all the photos at once. You can also make custom selections of images via the Filmstrip using the key to make continuous selections, or the key to make discontinuous selections of images. Once you have made a thumbnail selection you can then navigate the selected photos by using the navigation buttons in the bottom right section of the preview area to progress through them one by one and apply Camera Raw adjustments to the individual selected images. The Synchronize… button then allows you to synchronize the Camera Raw settings adjustments across all the images that have been selected, based on the current ‘most selected’ image. This will be the thumbnail that's highlighted with a blue border. When you click on the Synchronize… button, the Synchronize dialog ( Figure 3.15 ) lets
