Starting Photoshop and Viewing the Workspace To start Photoshop: Either launch Photoshop or open an existing Photoshop file Before opening or creating a new document, the workspace becomes available and consists of: The Menu bar (top of the screen) The Options bar (below the Menu bar) The Tools panel (on the left of the screen) The dock of panels (on the right of the screen)

Using the Zoom Tool and the Hand Tool Creating a marquee with the Zoom tool Adobe Photoshop CS6 - Illustrated Saving a Document and Understanding File Formats File formats: Specific types of computer code that are used to save images for various types of

output to use with other applications Standard file format for Photoshop files Adobe Photoshop CS6 - Illustrated Saving a Document and Understanding File Formats The key to choosing a file format Understand what the file is to be used for Save As dialog box

Adobe Photoshop CS6 - Illustrated Understanding and Changing Resolution A bitmap graphic is a graphic composed of pixels Pixel is a term that comes from the words pictures and elements A bitmap image is a grid of pixels All Photoshop files are bitmap graphics Resolution is a measurement of the number of pixels per inch (ppi) The higher the resolution, the greater number of

pixels A file 1X1 with a resolution of 100 pixels per inch would contain 10,000 pixels (100 pixels wide X 100 pixels high) Adobe Photoshop CS6 - Illustrated Understanding and Changing Resolution Image size: physical dimensions of the image-width and height File size: how large the file is in computer memory

Image resolutions and sizes Adobe Photoshop CS6 - Illustrated Changing Image Size Image size: Is not dependent on resolution Two files of the same dimensions can be created with two different resolutions Is related to resolution

All bitmap images regardless of physical dimensions have a resolution Changing the width and height of an image will affect the images resolution Resizing an image may have a negative effect on the images appearance Adobe Photoshop CS6 - Illustrated Changing Image Size When looking at an image for quality it should be viewed at 100% or larger

Image size Image size Adobe Photoshop CS6 - Illustrated Creating a New Document Many of the images that are worked on in Photoshop are either scanned or captured by a digital camera An image can also be created from scratch by creating a new document in Photoshop

A color model defines the colors that are seen and work with digital images RGB (red, green blue) CMYK (cyan, magenta, yellow, black) HSB (hue, saturation, brightness) In Photoshop a documents color mode is listed on the Image menu The color mode determines which color model is being used to display and print the image Adobe Photoshop CS6 - Illustrated

Color Models and Color Modes RGB is the standard color mode when working with digital images Selecting a color mode has an impact on which tools and formats are available All Photoshop tools and features are available in the RGB Color mode All files that are printed professionally must at some point be CMYK files Adobe Photoshop CS6 - Illustrated

Transforming the Canvas The bed of pixels making up an image is referred to as the canvas When an image is opened, it usually uses all of the pixels available on the canvas The canvas can be enlarged to add more pixels to the file Example: to make room for an additional image Adobe Photoshop CS6 - Illustrated

Transforming the Canvas Transform: refers to specific operations that are made to change the location of pixels Transformations include: Scaling Rotating Skewing and/or Distorting pixels For precise moves when transforming, use the arrow keys to more the image one pixel at a time

Adobe Photoshop CS6 - Illustrated Transforming the Canvas Canvas Size Dialog Box Adobe Photoshop CS6 - Illustrated Transforming the Canvas Viewing new pixels added to the canvas Positioning of second image over the new pixels

Adobe Photoshop CS6 - Illustrated Cropping an Image Cropping: Allows the definition of an area of an image that is wanted to be kept and the remainder of the image to be discarded Photoshops Crop tool: Makes it easy to execute a single crop Provides options for previewing the crop before it is executed Cropping an image can often be an artistic

choice A so-so image can be turned into an eyecatching one Adobe Photoshop CS6 - Illustrated Cropping an Image Creating a crop marquee The cropped image Adobe Photoshop CS6 - Illustrated

Cropping an Image Setting opacity for the Crop tool Opacity refers to how opaque something is When using the Crop tool, you can change the shield color and opacity of the area outside the crop using the Color and Opacity settings on the Options bar As a preview before cropping, many designers set the opacity to 50% while experimenting, then, when they think theyve found a crop that they like, they

increase the opacity to 100% Adobe Photoshop CS6 - Illustrated Cropping an Image to a Specific Size The Crop tool: number of options to execute more than just a simple crop After creating the crop marquee, the Crop tool pointer becomes an arrow pointer when inside the marquee Use the arrow to move the marquee to crop a different area of the image

The Crop tool pointer outside of the crop marquee is a rotate pointer Use the rotate pointer to rotate the crop marquee Specific width and height dimensions can be used to create a crop marquee of a specific size Adobe Photoshop CS6 - Illustrated Cropping an Image to a Specific Size When a specific width and height is entered

to crop an image to a specific resolution, using the Resolution text box on the Options bar can be also entered Makes the Crop tool function much like the Image Size dialog box No matter where an image is cropped or what size crop marquee is created, new pixels cannot be added or deleted, only redistributed Adobe Photoshop CS6 - Illustrated

Cropping an Image to a Specific Size Rotating the crop marquee The cropped, rotated, and resized image Adobe Photoshop CS6 - Illustrated Summary Photoshop CS6 offers a variety of tools to edit and manipulate digital images Three basic categories of graphics programs: vector, bitmap, and animation

File formats are used to save images for various types of output to use with other applications Photoshop files are bitmap graphics composed of pixels The greater the number of pixels, the higher the resolution of the image Adobe Photoshop CS6 - Illustrated Summary A bed of pixels comprises a canvas The canvas can be enlarged to add

additional pixels Pixels can be transformed by: Scaling, rotating, skewing, or distorting Cropping of an image allows for an area of the image to be used and the other parts to be discarded Adobe Photoshop CS6 - Illustrated
