Slide around the color bars to get your black and white photo to look exactly how you want it to look. The red and yellow sliders seem to make the biggest differences, although that obviously will depend on the colors in the photograph. Once you are satisfied with the balance you’ve found, click OK. It’s as simple as that.
You’ll notice that on the bottom of the Black and White box, there is a checkbox that says Tint. If you check that box, you can add a hue into the monochrome photo. You can pick the color by moving the Hue slider, and you can choose how strong that color comes through in your picture by adjusting the Saturation slider. Again, be sure to click OK to apply the changes to your photograph.
With the Black and White tool in Photoshop CS3, your control over the color and tint of your pictures is absolute. It’s a quick process and certainly much smarter than switching settings on a camera to get those antique, black and white photos.
