them via Bridge, but when you do this Photoshop then becomes tied up managing the Camera Raw processing and this prevents you from doing any other work in Photoshop. The advantage of opening via Bridge is that Bridge can be used to process large numbers of raw files in Camera Raw, while freeing up Photoshop to perform other tasks. You can then toggle between the two programs. For example, you can be processing images in Camera Raw while you switch to working on other images that happen to be already opened in Photoshop.

Regarding JPEG and TIFF images, Camera Raw can be made to open these as if they were raw images, but please refer to page 170 for a summary of the JPEG and TIFF handling behavior in Camera Raw.

General controls for single file opening

When you open a single image, you will see the Camera Raw dialog shown in Figure 3.11 (which in this case shows Camera Raw hosted via Bridge). The status bar shows which version of Camera Raw you are using and the make of camera for the file you are currently editing. In the top left section you have the Camera Raw tools, which I have listed on the left, and below that is the image preview area where the zoom setting can be adjusted via the pop-up menu at the bottom. The initial Camera Raw dialog displays the Basic panel control settings and in this mode the Preview checkbox allows you to toggle previewing any global adjustments that have been made in Camera Raw. Once you start selecting any of the other panels, the Preview toggles showing only the changes that have taken place within a particular panel.

Figure 3.11 This shows the Camera Raw dialog (hosted by Bridge), showing the main controls and shortcuts for the single file open mode. You can tell if Camera Raw has been opened via Bridge, because the Done button is highlighted. This is an ‘update’ button that you click when you are done making Camera Raw edits and wish to save these settings, but without opening the image. If you click on the Workflow options (circled), this opens the Workflow Options dialog shown in Figure 3.12 , where you can adjust the settings that determine the color space the image will open in, the bit-depth, cropped image pixel dimensions plus resolution (i.e. how many pixels per inch). You can also choose here to sharpen the rendered image for print or screen output. These options are relevant if you are producing a file to go directly to print or for a website. If you intend carrying out any type of further retouching then leave this set to ‘None’. Lastly, there is an option to open in Photoshop as a Smart Object (see pages 158–161).
