Real World Camera Raw with Adobe Photoshop CS- P342 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 O and Cancel buttons perform multiple duties. Clicking O K K dismisses the Camera Raw dialog box and converts the image using the settings specified in Camera Raw. Clicking Cancel closes Camera Raw, leaving the image unchanged, and no conversion takes place. When you hold down the Shift key, the O button changes to Skip. The K subtle difference between Skipand Cancel is that if you select multiple im- ages to openwithCameraRaw,Can~ancelcancels entire process,while Skip the simply skips the current image and opens the next one in Camera Raw. When you hold down the Option key, the O button changes to Update. K When you clickupdate, the currentsettings are written to the images meta- data without performingthe conversion and opening the image. The Cancel button changes to a Reset button, resetting any changes youve 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 and Advanced modes. The obvious difference between the two is that the Advanced mode adds two extra sets of image controls,Lens and Calibrate, which Ill discuss later in this chapter. A less obvious dif- ference is that Advanced mode also adds some commands to the Camera Raw menu, which Ill discuss shortly. Since youve bought this book and read this far, Ill assume that youre an advanced user and hence youll do what I do and keep the Advanced radio button turned on at all times. Figure 3-7 Gunera Raw main control buttons no modifier plus Shift plus Option The Histogram and RGB Readout The histogramdisplays thehistograms of the red, green, and blue channels that will be created by the current conversionsettings, notthe histogram of the raw image (whichwould lookstrange since digital cameras capture at linear gamma-all the image data would be scrunched over to the left). Chapter 3: Using Camera Raw 43 The histogram lets you check for black and white, just like the histo-grams on the Histogram palette, but it also lets you check for clippingcaused by colorsyouve capturedthat are outside the gamut ofyourchosenworking space (see Figure 1-5 in Chapter 1, Digital Camera Raw). you Iffind that the chosen workingspace is clipping some colors, you can selecta larger one- your color is clipping in ProPhoto RGB, youre probably ifcapturing something other than visible light! The histogram is a useful tool both for evaluating the unedited rawcapture and for checkingyour edits to make sure that you dont introduceany unwanted clipping. The RGB readout shows the RGBvalues that will result from the conver-sion at the current s e t t i n p i t shows the RGB value for the pixel under thecursor. See Figure 3-8. The RGB readout always reads 5-by-5 pixels at thecurrent view resolution, so it may give different values at dierent zoomlevels. When you fit the entire image into Camera Raws preview, youresampling an average of a fairly large number of pixels--the exact numberdependson both the cameras native resolution and the size youve chosenfrom the Size menu in the workflow controls (seeCamera RawWorkflowControls, later in this chapter).You cant really sample a single pixel, butin those rare cases where youd want to, sampling at 400% view will getyou very close.

(Ive seen situations where older versions of the plug-in listed all raw files open in the Fie Browser, whether they had associated saved settings or not, and choosing ones that didnt have saved settings just produced an error message.) Choosing an image from the Settings menu loads that images settings into Camera Raw. ...
