QUICK KEYS

CTRL+Z

If you don't like the effect of a filter you've just applied, or you've gone wrong with a brushstroke you can use Undo to take you back one step. Edit ?Step Forward/Step Backwards makes life even easier. It's like the History palette but uses shortcut keys to speed things up. Whatever you do can be simply undone. (For multiple undos see History palette )

Tip

  • Use Undo to revert to a previous setting when making adjustments to palette settings that have several options.

Use all Layers

Select this mode in the Rubber Stamp, Paint bucket or Sharpness/Blur/Smudge palettes to ensure the colors of all layers are considered when an effect is applied to the active layer. When Use all Layers is not selected only the colors in the active layer are sampled, cloned or smudged.

Here's what happens when we clone from a source image (Untitled 1) to a destination document (Untitled 2). The image has text on each of three layers. The first example (top) doesn't have Use All Layers selected. When you clone from source to destination only the active layer is picked up and cloned onto the new document. When Use All Layers is selected (right) all three layers are cloned.

Photographic Films
Photographic films are plastic sheets used to capture images by exposing the layers of plastic to light for specific periods of time, depending on the quality. They consist of sheets of plastic coated with an emulsion that forms a latent image when exposed to light.
Optical Bandpass Filters
Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light.
Lithography Equipment
Lithography equipment transfers circuit or device patterns onto a substrate using a patterned mask and a beam of light or electrons to selectively expose a photoresist layer. Overlay metrology systems align the pattern masks or reticules.
Semiconductor Wet Process Equipment
Semiconductor wet process equipment performs a variety of wet processing applications including etching, washing, chemical mechanical polishing (CMP), and spin coating in semiconductor or microelectronics manufacturing.
Flat Panel Displays
Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.
