Lesson 1 - 31stOct-4thNov

• BND - P1 - hardware and software required for image processing
  • Group activity: discuss and present on hardware in input, storage, processing and output groups, how they work with images.
  • Hand in 10th November.
• BNC - P4, P5 and M2 (basic skills and advanced skills)

Lesson 8

• Class -BND - hand in P4&P5&M2 - printout and annotated + email me for backup
• Class BNC - hand in P1, P2, P3 and P6 - email first. Some hand in for final and some for 1st draft.

Lesson 7 P4 & P5 - Creation of Images

• Question basketball: Name PS skills you have learned, Paint skills, Image processing in PowerPoint
• Learn to use MS Visio - vector graphics package -for the map - centre classroom signposts
• End products must
  • Demonstrate basic skills in Photoshop
  • Demonstrate basic skills in MS Visio
  • Demonstrate scanning and digital photographing skills
  • Annotated screenshots
  • End result is reviewed.
• Advanced skills for M2 - 2 or more (filter (lighting, extract, blur), layer effects, 3D, etc.)

Lesson 6 Digitising & Factors Influencing Image Quality

"The overall weight of ants on Earth is the same as the overall weight of all humans."

• LOs -
  • Learn about factors affecting the quality of images - file type and compression techniques;
  • Learn about different input methods (digitising devices)
  • These will help with P3, P4, P5, M1, M3 and D1
• Question Basketball:
• Demonstration: MS Paint
• Tasks - see this file for templates
  • Group of 3-4, one on computer to try the file types, the others on digitising methods (a sketch of logo).
  • First support team for the 4 on computers
  • Rotate and share with group
  • Share with class
• Question time
• Type up for drafts of M1 (partial), M3 (partial) - deadline is to be announced.

Lesson 5A Complete P3

"There are about ten thousand trillion ants in the world. Even the sharpest ear cannot hear an ant singing."

• Complete and email the draft to me as your P3.
• Must include your name in the filename

Lesson 5 Client, User, Audience and Graphics Designer (P3)

• Introduction: you are about to start the graphic design tasks after P1, 2, & 6. First you need to understand the requirements for the graphics to be designed.
• The objective is to understand the requirements of your client, user and audience. This is to ensure a satisfactory design meeting their requirements. (You are the graphic designer.)
• Know the purpose and operations of Studio N17 - three images for marketing the games they have produced - logo, map and poster.
• Define the Client, User, Audience and their relationship with you.
• Discuss and produce a list of requirements for you to follow.
• Share with class
• Write up and submit by the ned of next lesson as your P3
• Research: find and bring in some posters for game pormotions.

Lesson 4A - Complete P1, P2 and P6 for first submission

• Type up and email me the drafts. must be clearly named and labelled.
• Each document should have your name in the filename and the criteria (P1, P2 or P6)

Lesson 4 Legal Issues related to Images

• Copyright, Design and Patent Act - the main principles
• What does it mean to you when you use images created by others? What does it mean to you when you create an image?
• How to get permission?
• What if no permission is obtainable?
• Evidence: A presentation to explain all te above.
• Find a suitable image from the Internet. Identify its owner and try to get permission to use it. Evidence the process.

 

Lesson 3 Applying Knowledge (P1) to a Realistic Scenario

• LOs:
  • consolidate hardware and software knowledge
  • Apply to a real scenario to solve a problem.
• Question basketball: name a hardware device and describe how it works with images
• Group discussion: is each component suitable for image processing.Why? If not, what to replace it with?
• Share with class:
• Write up (report or presentation) as your P2. Then evidence in folder.

Lesson 2 Harware and Software for Image Processing

Hardware - 4 categories - input, storage, processing and output.

• create a presentation about them
• each device should include name, category, working principles (how it handles image)
• should include all relevant hardware devices,
• all should include a picture to iluustrate

Software - 4 types - vector graphics based, bitmap based, embedded facilities and photograph editing software

• create a presentation about them
• each should include include a list of the main features of the type

More features of Photoshop

• fill layer and shape layer
• filter (extract, blur)
• quick mask mode selection
• preset styles
• layer styles
• adjustment - layer, colour, levels, curves,
• resize - image- canvas size

Lesson 1 Start Practical Exercises

Familiarise with the workspace

• start a new file, size, resolution, colour, file size
• create new images - toolbox - paintbrush (size, colour, pattern); eraser (type, size); paint bucket (colour, opacity, tolerance); gradient (presets, new scheme), text (font, colour, warp, rasterising, re-editing); move tool; selection tool (regular shape marquee, lasso, polygonal lasso, magnetic lasso, magic wand); layer (add, delete, move, select, opacity); copy/paste from files or internet.
• edit image - text (before and after rasterising), image (edit-transform, free transform)
• output - save as PSD file, save as jpg, png,

Start an A3 poster for Studio N17 to promote their products.
