PHOTOSHOP BASICS – Adding Colour

Student will be able to:

1. Add several colours to one digital image.
2. Match colours used in a hand coloured colouring page image with colours created in Photoshop.
3. Open a Photoshop file.
4. Save a Photoshop file.
5. Use the Foreground/ Background tool, Colour Picker Tool and Paint Bucket tool from the Photoshop tool bar.

Have students:

1. Create and scan their own line drawing, then colour several versions of it in Photoshop. 

1. Prior to the lesson:
   - Introduce students to Photoshop and what it can be used to do, the basic screen layout, and the icons found in the Photoshop toolbar.
   - Have students familiarize themselves with the school computers.
2. Pre-load the Digital_Adding_Colour.pdf files onto the computers.
3. Pre-load the 3 colouring page Adding_Colour.pdfs onto the computer so students can select and print the one of their choice, OR print copies of each image ahead of time.
4. Download the Colour poster available on this website,
   Colour
5. Gather images from the Internet that show colour manipulation, for example,
   Helicopter
   Monument
   Landscape
   Contrast

1. Show students several examples of how colour has been digitally manipulated.
2. Have a class discussion based on the examples, e.g., likes, dislikes, simplicity, complexity, shading, colour choice, etc.
3. View the Colour Picker window as a class and discuss how it is used, 
   - What are Hue, Saturation and Brightness?
   - How can they be changed in Photoshop?
   - Why are Hue, Saturation and Brightness important in an image? 
4. Discuss how Hue, Saturation and Brightness are being changed with their own photos through apps found on their personal devices such as Instagram and Snapchat, for example,
   - Look at the editing features found in Photos & Camera on your personal device. How can you change the HSB?
   - Look at the editing features found in Instagram. How can you change the HSB?
   - Look at, or research apps like Snapseed. Have students download it and discuss HSB changes.
5. Ask students to look through their personal device for the best picture they have shot, then have them change the Hue, Saturation and or Brightness. 
   - Is their photo better or worse?
   - What do they see that makes them say that?
6. Introduce the challenge.

1. Once the work is complete ask students to share it in small groups.
   Ask them to:
   - Look closely at the hand coloured image as well as the PS image and determine whether they are a colour match.
   - Determine whether the individual followed the step-by-step instructions accurately.
   - Talk about the advantages and disadvantages of colouring with a computer vs. by hand.
   - Talk about what was difficult about hand colouring an image and then replicating it digitally.
2. Ask some of the students to share both of their images with the class.
3. Display the images in and around the classroom and school so students can view them as a body of work throughout the next few weeks.

1. Observe students as they work – attention to detail, transfer of knowledge from lesson to activity, collaboration with classmates
2. Observe students as they discuss their work – active listening, insightful contributions, supporting ideas with evidence found in the work and from personal experience.
3. Use a checklist to track progress. (Downloads – Photoshop-Adding_Colour_tracking.pdf)
4. Have students use the self-assessment form to evaluate their work. (Downloads – Photoshop-Adding_Colour_self-assessment.pdf)
