    ICC profiles: Color space descriptions that can be configured or installed for a specific device like a scanner or printer. ICC stands for and was defined by the International Color Consortium as a cross-platform color standard.

    Image: From the Image menu choices, you can make adjustments to the image concerning color, hue, saturation, and other attributes, as well as make changes to the color mode. Other options allow you to duplicate, trim, rotate, crop, and trap the image, and change the image size.

    Image Ready: A second application that ships with Photoshop 7.0 and is used mainly for web design.

    Import: Available from the File menu, this command lets you import files from a scanner or digital camera and import PDF images, annotations, and WIA support. PDF (Portable Document Format) is the primary file format for Adobe Illustrator and Adobe Acrobat.

    Impressionist: Adds an impressionist effect (like Monet’s art) when the box is checked while using the Pattern Stamp tool.

    Indenting text: Left indent indents a paragraph from the left edge of the paragraph, right from the right edge, and first line to only indent the first line of the paragraph.

    Indexed color: This mode uses from 1 to 256 colors. You can convert an RGB image to an indexed color image, and Photoshop will look at the colors and convert them to the colors available in the indexed color model. Indexed color can be used for web images but is used in screen printing as well. Screen printers can use indexing to color separate an image using only a few colors, and those colors can be hand picked.

    Info palette: Displays color information about the color directly underneath the mouse pointer and displays additional information depending on the tool chosen.

    Interpolation: Photoshop’s way of figuring out what should be in a specific pixel when enough information isn’t given, such as when you resample an image. If you start with a small image and try to double the size, Photoshop has to guess at what’s supposed to be in those extra areas. If you take a large image and reduce its size, it has to guess at what to throw away. There are several types of interpolation: Bicubic, Bilinear, and Nearest Neighbor.
