TAILIEUCHUNG - Real World Camera Raw with Adobe Photoshop CS- P5

Real World Camera Raw with Adobe Photoshop CS- P5: 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. | 102 Real World Camera Raw wMfi Adobe Photoshop cs These settings eliminate the color fringe. Figure 3-43 Chromatic Aberration corrections continued The Calibrate tab. I ve already covered the intendeduse ofthe Calibrate tab controls fine-tuning the color rendering for a specific camera in detail earlier in this chapter. Here I ll look at some creative uses cf the controls. One non obvioususeof the Calibrate tab which I must credit to Adobe evangelist raconteur bon vivant and demomeister Russell Brown is in color to grayscaleconversions. Start by reducing the Saturationcontrol in the Adjust tab to 100 and then move to the Calibrate tab. The Hue slid ers control the panchromatic response while the Saturation controlslet you modulate the strength of the Hue controls effect. Figure 3 44 shows examplesof different black and white conversions alongwith thesettings that produced them. Note that the ideal values will vary from camera to camera but the ones shown here should get you in the ballpark. These conversions approximatethe use of traditionalcolor filters but you aren t limited to this approach you can createintermediatesettings or make image specific conversions. If you re going for natural it s probably a bad idea to use the Calibrate controls as selective color correction tools selective color cor rections are better left for you can certainly use them for creative color effects like the one in Figure 3 45 Chapter 3 Using Camera Raw 103 Color to grayscale Figure 3-44 2002 Jeff Schewe Co or image Starting with the color image reduce the Saturation slider in the Adjust tab to zero to get a image and then adjust the Calibrate controls to the panchromatic response. 104 Real World Camera Raw with Adobe Photoshop cs Figure 3-45 Creative color with Calibrate The image as shot The image after drastic moves with the Calibrate controls Saving Settings If you had to adjust every slider on every image you might reasonably conclude that Camera Raw was an instrument of torture
