Real World Camera Raw with Adobe Photoshop CS- P3: If you're reading this book because you want to be told that digital really is better than film, look elsewhere. Those discussions tend to generate a lot more heat thanlight, andifyouaren't at least contemplatingshootingdigital for some or all of your work, this book isn't relevant. | 42 Real World Camera Raw with Adobe Photoshop CS Rotate controls. The Rotate 90 Degrees Left and Right controls press L and R respectively let you apply a rotation to the preview that will be honored in the final conversion. The Main Control Buttons Both the CK and Cancel buttons perform multiple duties. Clicking CK dismisses the Camera Raw dialog box and converts the image using the settings specified in Camera Raw. Cancel closes Camera Raw leaving the image unchanged and no conversion takes place. When you hold down the Shift key the CK button changes to Skip. The subtledifference between Skip and Cancel is that if you select multipleimages to open with Camera Raw Cancel cancels the entire process while Skip simply skips the current image and opens the next one in Camera Raw. When you hold down the Option key the CK button changes to Update. When you click Update the currentsettings are writtento the image s metadata without performingthe conversion and opening the image. The Cancel button changes to a Reset button resettingany changes you ve made in Camera Raw and leaving the Camera Raw window open. See Figure 3-7. The Basic and Advanced radio buttons unsurprisingly let you toggle between Basic andAdvanced modes. The obvious difference between the two is that theAdvanced mode adds two extra sets of image controls Lens and Calibrate which I ll discuss later in this chapter. A less obvious dif-ferenceis that Advanced mode also adds some commandsto the Camera Raw menu which I ll discuss shortly. Since you ve bought this book and read this far I ll assume that you re an advanced user and hence you ll do what I do and keep the Advanced radio button turned on at all times.
