Study Sheet for Graphic Programming Test#2

 

1.      Identify, label, and describe the common parts of the Photoshop Interface.

A. Menu bar B. Shortcuts bar C. Options bar D. Toolbox E. Palette well F. Palettes

Menu bar The menu bar contains menus for performing tasks. The menus are organized by topic. For example, the Layers menu contains commands for working with layers.

Shortcuts bar The shortcuts bar displays buttons for executing common commands. (See Using the shortcuts bar.)

Options bar The options bar provides options for using a tool. (See Using the options bar.)

Toolbox The toolbox holds tools for creating and editing images. (See Using the tools.)

Palette well The palette well helps you organize the palettes in your work area. (See Using the palette well.)

Palettes Palettes help you monitor and modify images. (See Using palettes.)

3.  Give common keyboard shortcuts for Photoshop.

 

      Zoom In = Ctrl +  -(minus key), Zoom Out = Ctrl + + (add key)

      New Layer = Shift + Crtl + N, Select All = Ctrl + A, Copy = Ctrl + C,

      Cut = Ctrl + X, Paste = Ctrl + V, Fit on Screen = Ctrl + O,

      Merge Down = CTRL + E, Group = Ctrl + G, Ungroup = Shift + Ctrl + G

 

4.   Describe what a layer is in Photoshop and explain the advantages of using

      layers to create an image.

 

        In Photoshop and many other graphic applications, a layer is a component in a complex image that consists of multiple layers. Each layer is like a transparent sheet upon which the user may draw or insert an image object.

 

      Each transparency contains part of a single image. One transparency might have the background. One transparency might have text. Another transparency might display the company logo. You can view each transparency by itself, or you can stack the transparencies on top of one another and view the stack as one image by projecting the stack on the overhead projector.

 

      It is the same with layers in a graphics application. You can work with or view each layer by itself, or you can combine them (it's called flattening) and view the "stack" of layers as one image. Layers are useful because they allow you to move and manipulate parts of an image to see how your changes affect the whole.

 

5.   Describe the difference between vector and bitmapped images and tell how this explains why you can’t paint on a shape object in Photoshop until you merge or flatten the shape layer and thus change it from a vector image into a bitmapped image.

 

      Vector graphics - is the creation of digital images through a sequence of commands or mathematical statements that place lines and shapes in a given two-dimensional or three-dimensional space. Vector graphics can’t be drawn or painted over because they are not bitmapped images, they are just formulas for creating an image.

 

Bitmapped Graphics (Raster image) — A bitmapped graphic is an image made using a grid of dots (pixels), also known as raster format. A bitmapped image has a fixed resolution, therefore, enlarging the graphic causes it to become coarse or stair-stepped.
