Customize Photoshop for Your Projects- P7: Using Photoshop CS5 you can improve photographs, repurpose them, or start with a blank canvas to create original designs. Because printed images and Web images have different limits on the range of colors that they can represent, you need to set the working color space for your project. | Create a dynamic black-and-white image with NIK SILVER EFEX PRO Photoshop CS5 s Adjustments panel includes many presets and adjustments for converting a color photo to black and white nondestructively. Nik Software s Silver Efex Pro is a sophisticated and yet easy-to-use tool for converting color images to grayscale and re-creating the different techniques for traditional darkroom photographic film processing. As with other Nik plug-ins Silver Efex Pro enables you to selectively control the tones and contrast in the image with the U Point technology. Silver Efex Pro conversions have the look of traditional film black-and-white images because the Nik plug-in re-creates the film grain from the pixels in the photo instead of overlaying a grain pattern as with other digital conversions. You can also select a black-and-white film type so your final image more closely emulates the look of a grayscale photo shot with film. Silver Efex Pro includes a number of presets including tints and toners so you can vary the resulting conversion in numerous ways. You can add a vignette or burned-in edges and you can even save your own settings as presets. You can download a trial version to use with your images at .
