A W A R D S & C U S T O M I Z A T I O N T H E D I G I T A L E Y E WHITE POINT BLACK POINT e Levels feature can be used to assign neutral highlight and shadow colors to the lightest and darkest areas of the image. With the WPBP technique, all the colors in the image will remap the brightness information based on the light and dark extremes of the image. In practice, this will usually produce the best contrast and completely eliminate any colorcast in just a few steps. What follows is the step-by- step workflow: 1.) Here is the "Dream Car" (Fig. 7), and it runs just fine. It can go 0-60 in 2.2 seconds! But it desperately needs a contrast 6 6 G R A P H I C S P R O • S E P T E M B E R 2 0 2 2 G R A P H I C S - P R O. C O M The "Dream Car" needs a contrast adjustment, and its murky yellow colorcast needs to be removed. 7 The light area on the rear of the car is the white point and the left front tire is the black point. 8 adjustment and its murky yellow colorcast needs to be neutralized. 2.) Drag over the image with the Color Sampler tool. Read the numbers in the Info panel to find the lightest area of the image and click to establish the white point (#1). In this case, it's the light area on the rear of the car. Remember, don't choose a specu- lar highlight for the white point, and don't choose absolute black (0 R, 0G, 0B) for the black point. Choose the areas with the low- est numbers and click to deposit (#2). In this case, it's the left front tire. (Fig. 8) 3.) Click the Levels icon in the Adjustment panel. Click on the white eyedropper on the panel to display the Color Picker. Enter these recommended values in the RGB fields for the white point: 240R, 240G, 240B that produces a very light gray. Click OK. en click on the black eyedropper on the panel to again display the Color Picker. Enter these recommended values in the RGB fields for the black point: 25R, 25G, 25B to produce a very dark gray. Click OK. (Fig. 9) 4.) Choose the white eyedropper again. On the image, click sample point #1. e image lightens. 5.) Choose the black eyedropper. Click on sample point #2. e image adjusts to perfect tonality. When the light and dark extremes are adjusted using the WPBP method, all of the colors are remapped, and everything usually falls nicely into place as you can see in Fig. 10.
