1. LESSON 6
Module 4: Working with Images
Scanning, Part I

2. In this lesson, we will:
Learn when and why scanned images are appropriate for the Web.
Practice using a scanner and making appropriate choices, depending on the image and output.
Create a sketch using line art (black marker) that will be scanned in the next lesson.

3. Guiding Questions
In Web design, when is there a need for scanning images?
How can the designer manipulate an image by scanning?
Why is the resolution important when scanning?
Use the guiding questions as a class starter, allowing the students time to answer the questions in their journal. Discuss student answers to the questions.

4. Web sites What Is a Logo: Visual Literacy: http://k-8visual.info/
Presenting Effective Web Graphics:
Use Web sites to give background information and show examples.

5. Scanning Activity Participate in class discussion

Student activity: T.4.6.WS_Scan (Scanning Outline)
Participate in class discussion/take notes on the Scanning Outline.
Observe the scanning process and continue to take notes on the Scanning Outline.
Sketch a caricature of your favorite pet, teacher, or food. Sketch the picture with pencil and outline with a fine-tip black marker. This will be used to scan in line art mode in the next lesson.

Summary and Vocabulary
During this lesson, we learned about the different scanning modes. We discussed resolution and file type selection. We looked at how to scan using a flatbed scanner.
Scanning Modes: Scanning modes refers to the various ways to scan images such as, line art, halftones, grayscale, color, true color, spot color, and scanning with a specific palette.

7. Assessment Why and when would you use a scanner in Web design?
A client would like to scan a color photograph of broken glass, but would like the photo to create a dramatic impact. What scanning mode would you choose and why?
When would a designer use black-and-white scanning mode?
Ask students to answer the questions in their journal, with a partner, or as a whole class.
