What's new in Camera Raw 7.0
Camera Raw 7.0 offers some further image processing refinements. In particular, there is now a new Process 2012 option in which the main Basic panel controls have been completely revised to provide more extensive editing capabilities for both raw and non-raw images. In fact, if you are familiar with the image editing controls in Adobe Revel for tablet devices, you'll already have seen how these work. The main Process 2012 sliders are also available as localized adjustments, along with new Temp and Tint adjustment controls. Lastly, the Tone Curve panel now also offers an RGB point curve editing option.
Figure 1.104 When you select a single raw image in Bridge, and double-click to open, you will see the Camera Raw dialog shown here. The Basic panel controls are a good place to get started, but the Auto button can often apply an adjustment that is ideally suited for most types of images. Once you are happy, click on the Open Image button at the bottom to open it in Photoshop. TIP: If you click on the Full Screen mode button in Camera Raw (circled above in blue), you can quickly switch the Camera Raw view to Full Screen mode.
Saving from raw files
If you save an image that's been opened up from a raw file original, Photoshop will by default suggest you save it using the native Photoshop (PSD) file format. You are always forced to save it as something else and never to overwrite the original raw image. Most raw formats have unique extensions anyway like .crw or .nef. However, Canon did once decide to use a .tif extension for some of their raw file formats (so that the thumbnails would show up in their proprietary browser program). The danger here was that if you overrode the Photoshop default behavior and tried saving an opened Canon raw image as a TIFF, you risked overwriting the original raw file.
Opening photos from Bridge via Camera Raw
If you double-click to open a raw or DNG image via Bridge, these will automatically open via the Camera Raw dialog shown in Figure 1.104, where Photoshop will host Camera Raw. Alternatively, if you choose File ➯ Open in Camera Raw... via the Bridge menu, this will open the file in Camera Raw hosted by Bridge. The advantage of doing this is that it allows you to free up Photoshop to carry on working on other images. If you choose to open multiple raw images you will see a filmstrip of thumbnails appear down the left-hand side of the Camera Raw dialog, where you can edit one image and then sync the settings across all the other selected photos. There is also a preference setting in Bridge that allows you to open up JPEG and TIFF images via Camera Raw too.
I would say that the main benefit of using Camera Raw is that any edits you apply in Camera Raw are nonpermanent and this latest version in Photoshop CS6 offers yet further major advances in raw image processing. If you are still a little intimidated by the Camera Raw dialog interface, you can for now just click on the Auto button (circled in red in Figure 1.104). When the default settings in Camera Raw are set to Auto, Camera Raw usually does a pretty good job of optimizing the image settings for you. You can then click on the 'Done' or 'Open Image' button without concerning yourself too much just yet with what all the Camera Raw controls do. This should give you a good image to start working with in Photoshop and the beauty of working with Camera Raw is that you never risk overwriting the original master raw file. If you don't like the auto settings Camera Raw gives you, then it is relatively easy to adjust the tone and color sliders and make your own improvements upon the auto adjustment settings.
There are some hidden items in Photoshop. If you drag down from the system or Apple menu to select About Photoshop..., the splash screen reopens and after about 5 seconds the text starts to scroll telling you lots of stuff about the Adobe team who wrote the program, etc. Hold down opt/alt and the text scrolls faster. Last, but not least, you'll see a special mention to the most important Photoshop user of all... Now hold down cmd/ctrl-alt and choose About Photoshop... Here, you will see the Superstition beta test version of the splash screen (Figure 1.105 below). When the credits have finished scrolling, carefully control/alt-click in the white space above the credits (and below Superstition) to see what are known as Adobe Transient Witticisms appearing one at a time above the credits. Being a member of the team that makes Photoshop has many rewards, but one of the perks is having the opportunity to add little office in-jokes in a secret spot on the Photoshop splash screen. It's a sign of what spending long hours building a new version of Photoshop will do to you. And if you are looking for the Merlin begone Easter egg, associated with the Layers panel options, well, Merlin is truly begone now!
