Vector- and pixel-based images
This subtopic explores the fundamental differences between vector and pixel-based images, including their creation, editing, and appropriate uses in media production. Learners will develop practical skills in using industry-standard software to produce both types of images and critically evaluate their effectiveness for specific purposes.
Assessment criteria
Learning Objectives
What you need to know and understand
- Compare the technical properties of vector and pixel-based images
- Create vector-based images using appropriate software tools
- Create pixel-based images using appropriate software tools
- Evaluate the suitability of vector and pixel-based images for different media outputs
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately describing the mathematical basis of vector graphics (paths, anchor points, curves) versus raster grids of pixels
- Award credit for demonstrating correct use of vector tools (e.g., pen tool, shape tools, path operations) to create scalable artwork
- Award credit for demonstrating correct use of pixel-based tools (e.g., selection tools, layers, brushes, filters) to create detailed raster images
- Award credit for providing a reasoned evaluation of when to use vector vs pixel-based images, referencing factors like scalability, file size, and output medium
Assessment Guidance
Guidance for achieving higher grades
- 💡When evaluating images, always link technical features to the intended use (e.g., logo for print vs web banner)
- 💡In practical tasks, save working files in native formats (e.g., .ai, .psd) and export appropriate final formats (e.g., .svg, .png, .jpg)
- 💡Use layers and naming conventions to organise your work – this demonstrates professional practice
- 💡For distinction, provide a comparative analysis of two or more images, justifying why one format is superior for a given context
Common Mistakes
Common errors to avoid in your coursework
- Confusing vector and pixel-based terminology (e.g., calling a vector file 'rasterised')
- Assuming all images can be infinitely scaled without quality loss
- Neglecting to consider output resolution when creating pixel-based images for print
- Using inappropriate software for the image type (e.g., trying to create detailed photorealistic images in vector software)
