Assessment Guidance
Guidance for achieving higher grades
- 💡Familiarise yourself with common software like Photoshop or GIMP.
- 💡Practice using selection tools and adjustment layers.
- 💡Always keep original files and work on copies.
- 💡Practise using layers and masks to combine images seamlessly.
- 💡Know the difference between raster and vector formats.
- 💡Always keep a backup of original images before editing.
- 💡Practice using keyboard shortcuts for efficiency.
- 💡Save work in appropriate file formats.
- 💡Understand the difference between raster and vector graphics.
- 💡When completing assignments, always provide annotated screenshots showing the use of core tools and techniques to demonstrate understanding.
- 💡Plan your composite image by sketching a layout and gathering all source materials before starting the editing process to save time and maintain consistency.
- 💡Check the assessment criteria carefully to ensure all required manipulations (e.g., cropping, colour adjustment, retouching) are evidenced.
- 💡Learn keyboard shortcuts for common editing tasks.
- 💡Use layers to non-destructively edit images.
- 💡Always keep a backup of original files.

Common Mistakes
Common errors to avoid in your coursework
- Using low-resolution images that appear pixelated.
- Neglecting to save work in appropriate formats.
- Over-editing, resulting in unnatural images.
- Over-compressing images, losing quality.
- Ignoring resolution and aspect ratio when combining images.
- Using too many effects, making images look unprofessional.
- Not maintaining original image quality when resizing.
- Overusing filters, leading to unnatural results.
- Poor layer management causing confusion.
- Students often forget to lock or hide layers before editing, leading to unintended modifications.
- A frequent error is resizing raster images beyond their original resolution without using proper resampling, causing pixelation.
- Many learners neglect to save work in a layered format (like PSD) before exporting to a flat format, losing editing flexibility.
- Using low-resolution images that appear pixelated.
- Over-editing, making images look unnatural.
- Not saving in the correct file format for the intended use.
- Using low-resolution images that appear pixelated.
- Forgetting to save original files before editing.
- Over-editing resulting in unnatural images.
- Forgetting to flatten or export images in the correct file format for the intended purpose, leading to compatibility issues.
- Overusing automatic adjustments without understanding their impact on image quality and resolution.
- Neglecting to name layers clearly, making the file difficult to navigate and edit later.
- Confusing image resolution with physical dimensions, resulting in prints that are pixelated or incorrectly sized.
- Applying filters directly to the original image layer instead of using smart filters or duplicates, causing irreversible changes.
- Working on flattened layers, losing editability.
- Overusing filters, making images look unnatural.
- Not saving in correct resolution for output.
- Misconception: The SDLC is always a linear, waterfall process. Correction: While the waterfall model is one approach, modern practice often uses iterative or agile methods where phases overlap and repeat based on feedback.
- Misconception: Network security is only about firewalls and antivirus. Correction: Effective security also involves user training, access controls, regular updates, and incident response planning.
- Misconception: Database normalization always improves performance. Correction: Over-normalization can lead to complex joins and slower queries; sometimes denormalization is used for performance optimization in read-heavy systems.
