Other Filters | Photoshop CS Savvy

Two filters ”Video and Digimarc ”exist in a category by themselves , being neither constructive, destructive nor effects for Render filters.

Video Filters

The Video ’ NTSC Colors filter has one purpose: to convert the colors of an image for transfer to videotape. This filter is not a color space. It converts your RGB images to NTSC (National Television System Committee)-compatible colors.

If you continue to work on an image after using this filter, you might introduce incompatible colors. A better solution is to close the file, head to the Color Settings, and choose the NTSC RGB color space as your working RGB space. Then reopen the file and OK the profile conversion in the dialog box that appears.

The Video ’ De-Interlace filter regenerates missing interlacing rows from video grabs. When you capture an image from a video device, the results might be less than satisfactory due to the interlacing used by the video program to compress file sizes. The De- Interlace filter restores the image by replacing pixel data. The result is that the image appears smoother. You can choose to replace interlaced fields by duplication or interpolation.

Digimarc Filter

The Digimarc filter lets you embed a digital watermark on your image to protect your copyright. It s particularly useful to professionals who license their work. Code is added to the document as noise and is usually imperceptible to the human eye. The watermark can endure most editing, even filters and file conversion.

To embed a digital watermark:

Choose Filter ’ Digimarc ’ Embed Watermark.
You must first register with Digimarc Corporation to get a creator ID. Click Personalize to launch your browser and access the Digimarc website at www.digimarc.com, or call the phone number in the dialog box.
Enter the PIN and ID number in the creator ID box. Click OK.
In each field, enter information about the image, including the copyright date and usage information.
Select a Visibility and Durability value. The more visible the watermark is, the more durable it is.
Click OK.

After you ve embedded the watermark in an image, test its durability with the Signal Strength meter. Choose Filter ’ Digimarc ’ Read Watermark. The meter will tell you under what conditions the watermark will survive a specific intended use.
