TOOLBOXES

LAYERS

Layers allow you to work on one element of an image without disturbing the others. Think of layers as sheets of acetate stacked one on top of the other. Where there is no image on a layer, you can see through to the layers below. You can change the composition of an image by changing the order and attributes of layers.

PAINT- AND DRAWING TOOLS

Pencil & Brush

Erase tool

Retouch

Manipulating a picture

Polygons/vector

Text tool

HISTORY PALETTE

The History palette lets you jump to any recent state of the image created during the current working session. Each time you apply a change to an image, the new state of that image is added to the palette.

For example, if you select, paint, and rotate part of an image, each of those states is listed separately in the palette. You can then select any of the states, and the image will revert to how it looked when that change was first applied. You can then work from that state.

FILTERS

To apply a filter to an area of a layer, select that area. To apply a filter to the entire layer, leave the image unselected.

Choose a filter from the submenus in the Filter menu. If a filter name is followed by ellipses (), a dialog box appears.

If a dialog box appears, enter values or select options.

RGB

A large percentage of the visible spectrum can be represented by mixing red, green, and blue (RGB) colored light in various proportions and intensities. Where the colors overlap, they create cyan, magenta, yellow, and white.

Because the RGB colors combine to create white, they are also called additive colors. Adding all colors together creates white. Additive colors are used for lighting, video, and monitors. Your monitor, for example, creates color by emitting light through red, green, and blue phosphors

CMYK

The CMYK model is based on the light-absorbing quality of ink printed on paper

In theory, pure cyan (C), magenta (M), and yellow (Y) pigments should combine to absorb all light and produce black. For this reason these colors are called subtractive colors. Because all printing inks contain some impurities, these three inks actually produce a muddy brown and must be combined with black (K) ink to produce a true black. (K is used instead of B to avoid confusion with blue.) Combining these inks to reproduce color is called four-color process printing.

The subtractive (CMYK) and additive (RGB) colors are complementary colors. Each pair of subtractive colors creates an additive color, and vice versa.
