Domain 2 0 identifying design elements when preparing images

Domain 2.0 Identifying Design Elements When Preparing Images

  • Domain 2 focuses on design elements and image composition.

  • This domain is similar to the second domain in the Web Communication (Dreamweaver CS5) and Rich Media Communication (Flash CS5) certification objectives.

Photoshop domain 2 identifying design elements when preparing images

Objective 2.1 Demonstrate Knowledge of Image Resolution, Image Size, and Image File Format for Web, Video, and Print

  • Resizing an Image

  • The Image Size dialog box displays the image data, which includes the number of pixels in an image, the size of the image in inches, and the resolution.

Objective 2.1 Demonstrate Knowledge of Image Resolution, Image Size, and Image File Format for Web, Video, and Print (cont.)

  • Resizing an Image

  • To change the image data, which affects the resolution and file size, you must resample the image, which increases or decreases the number of pixels contained in the image.

  • Photoshop uses a method called interpolation to resample an image, using existing pixel colors to create new color values.

  • You can crop an image to resize it. Cropping allows you to remove the outside portion of an image to correct its focus.

Objective 2.1 Demonstrate Knowledge of Image Resolution, Image Size, and Image File Format for Web, Video, and Print (cont.)

  • Printer Resolution

  • The resolution on a printer is measured in ink dots per inch (dpi). The more dots per inch, the higher the image quality.

  • This actual number of printer dots is referred to as screen frequency, screenruling, or linescreenfrequency and is measured in lines per inch (lpi).

  • When preparing your image for print, it is often easier to specify your image in the printed dimensions, often referred to in inches, as well as the image resolution; this is referred to as the document size.

Objective 2.1 Demonstrate Knowledge of Image Resolution, Image Size, and Image File Format for Web, Video, and Print (cont.)

  • File Formats

  • There are many different file formats available for graphics. It is important to choose the correct file format for how and where the image will be used.

  • Image Optimization

  • The Save for Web & Devices command on the File menu provides a method to optimize images for publishing on the web and mobile devices.

Quick quiz

Quick Quiz

  • What is a pixel?

    • Answer: A single point in a picture laid out in rows and columns.

  • True or False? Scaling an image to resize it changes the image data.

    • Answer: False.


Class discussion

Class Discussion

  • Review Table 2-2 that describes the most commonly used file formats for graphics. Discuss the importance of choosing the correct file format for how and where an image will be used, such as the web, video, photos, print, a Microsoft PowerPoint presentation, or a Microsoft Word document.


Lab activity

Lab Activity

  • Complete Step-by-Step 2.1, which provides practice resizing and optimizing an image.


Objective 2 2 demonstrate knowledge of design principles elements and image composition

Objective 2.2 Demonstrate Knowledge of Design Principles, Elements, and Image Composition

  • Graphic design includes design elements, design principles, and image composition. It is important to understand some concepts to be able to create an attractive layout.

  • Image Composition and Principles

  • An image composition is the arrangement of the visual elements of your image to create a visually compelling design.

  • When composing or laying out your design, there are some basic concepts you should consider for your graphic design project, such as aspect ratio, framing, field of view, foreground, and background.

Quick quiz1

Quick Quiz

  • What is the aspect ratio of an object?

    • Answer: The relationship of an object’s height to its width.


Class discussion1

Class Discussion

  • Review each of the design elements and design principles in Table 2-3 and discuss the importance of understanding design concepts in order to be able to create an attractive layout. How can you achieve balance by applying symmetry or asymmetry?


Lab activity1

Lab Activity

  • Complete Step-by-Step 2.2, which provides practice cropping an image.


Objective 2 3 demonstrate knowledge of typography

Objective 2.3 Demonstrate Knowledge of Typography

  • When adding text to a digital image it is important to consider the font, style, color, and spacing.

  • The selections made to design the text and the placement of the words are called typography.

  • Readability is the feeling that is conveyed to make the typeface comfortable and easy to read.

Quick quiz2

Quick Quiz

  • What is readability?

    • Answer: The feeling that is conveyed to make the typeface comfortable and easy to read.


Lab activity2

Lab Activity

  • Locate a graphic image that includes text in a magazine, flyer, web page, or other source and evaluate its readability. Are there any changes that could be made to the size, style, or alignment of the text to make it more readable?


Objective 2 4 demonstrate knowledge of color correction using photoshop cs5

Objective 2.4 Demonstrate Knowledge of Color Correction Using Photoshop CS5

  • RGB color mode uses red (R), green (G), and blue (B) in various combinations to create the colors you see on a computer display, a television screen, or a movie in a theatre.

  • CMYK color mode uses cyan (C), magenta (M), yellow (Y), and black (K) to create various colors in print.

  • Colors that are in a range that can be displayed or printed are referred to as a gamut.

Objective 2.4 Demonstrate Knowledge of Color Correction Using Photoshop CS5 (cont.)

  • You can use the Histogram panel to interpret colors in an image.

  • High dynamic range (HDR) images allow a photographer to record a much larger range of tonal detail than can be captured in one photo.

Quick quiz3

Quick Quiz

  • Which color mode would you use when submitting your graphic design to be printed?

    • Answer: CMYK

  • How would you view colors that are out of gamut?

    • Answer: Click View on the Application bar (Win) or Menu bar (Mac), and then click Gamut Warning. The colors outside the range are highlighted in gray.


Lab activity3

Lab Activity

  • Open an image and use the Proof Setup command to view the image’s simulated output in a variety of options, such as type or color of paper. Which option would you use to proof for color blindness?

Objective 2.5 Demonstrate Knowledge of Image-Generating Devices, Their Resulting Image Types, and How to Access Resulting Images in Photoshop

  • You can create an image with a digital or film camera and from scanning an image.

  • The Open command opens each image into its own Photoshop document.

  • The Place command allows you to place multiple images into a single document.

  • You can scan images directly into Photoshop by clicking File on the Application bar (Win), pointing to Import, and then clicking WIA Support.

Quick quiz4

Quick Quiz

  • True or False? Camera Raw files are much larger than JPEG files, sometimes two to six times larger.

    • Answer: True

  • What is the difference between the Open command and the Place command on the File menu?

    • Answer: The Open command opens each image into its own Photoshop document. The Place command allows you to place multiple images into a single document.


Objective 2 6 understand key terminology of digital images

Objective 2.6 Understand Key Terminology of Digital Images

  • Bitmap vs. Vector Graphics

  • A bitmap image, technically known as a raster image, is represented by pixels in a grid layout; each pixel contains color information for the image.

  • A vector image is created with mathematical calculations and can be enlarged without a loss of quality.
