ptg Manipulating Images with Filters Introduction Adobe Photoshop filters are a designer's dream come true. With filters you can turn a photograph into an oil painting or a watercolor; you can even change night into day. Photoshop's Filter menu includes no less than 105 highly cre- ative filters, which can be applied once, reapplied, or com- bined with other filters to create any effect your imagination can dream up. The potential combination of filters and images literally runs into the millions. This means that Photoshop filters are truly an undiscovered territory. As a matter of fact, the Filter Gallery lets you view the effects of one or more filters on the active document. This level of power gives you unbelievable creative control over your images. Other commands, such as the Fade command, let you reduce the effect of the applied filter. You can even apply a blending mode to the final image. In addition, you can utilize a channel mask to control how the filter is applied to the image. You could also use a black to white gradient channel mask to slowly fade the effects of the filter from left to right. Photoshop even lets you protect your intellectual property by embedding a customizable watermark into the image that is almost invisible to see, and virtually impossible to remove. In fact, you can print an image that contains a watermark, run it off on a copy machine and rescan it, and the watermark is still there. Now that's protection.
