    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Identifies techniques for image manipulation.
    • Uses software tools to manipulate images effectively.
    • Produces a final manipulated image that meets a brief.
    • Demonstrates correct use of selection and layering tools.
    • Applies colour correction and retouching appropriately.
    • Creates a composite image that is realistic and well-blended.
    • Saves and exports images in suitable formats for intended use.
    • Award credit for demonstrating the ability to open, navigate, and save images in appropriate file formats (e.g., JPEG for web, PNG for transparency, PSD for editable master files).
    • Evidence must show correct use of at least two selection tools (e.g., rectangular marquee, lasso, magic wand) to isolate and modify specific areas of an image.
    • Learner must apply at least one non-destructive adjustment layer (e.g., brightness/contrast, hue/saturation, levels) to alter image appearance without permanently changing original pixels.
    • Work should include clear annotation or a brief written reflection identifying the tools and techniques used, explaining why they were chosen and how they contribute to the final manipulated image.
    • Identify tools and techniques for image manipulation.
    • Produce manipulated images to meet a brief.
    • Explain ethical considerations in image manipulation.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Practice using layers and masks for non-destructive editing.
    • 💡Always keep a copy of the original image.
    • 💡Check the final image for resolution and colour consistency.
    • 💡Practise using layer masks for non-destructive editing.
    • 💡Always work on a copy of the original image.
    • 💡Check resolution and colour mode before final output.
    • 💡Always document your workflow with screenshots or step-by-step notes to provide strong evidence for the 'Know how' criterion and support your final submission.
    • 💡Carefully read the assignment brief to ensure your manipulated image meets all specified technical requirements, such as exact dimensions, resolution (e.g., 72 ppi for web), and color mode (RGB).
    • 💡Back up your working files (e.g., PSD) regularly to avoid losing unsaved edits, and keep versions to track progress.
    • 💡Use non-destructive editing techniques like adjustment layers and smart objects wherever possible, allowing you to refine the image later if feedback is given.
    • 💡Perform a final quality check by viewing the image at 100% zoom to spot any leftover fringe pixels or misalignments, and ask a peer to review your work before submission.
    • 💡Use layers and non-destructive editing techniques.
    • 💡Save original files for reference.
    • 💡Tip 1: For practical tasks, read the instructions carefully. Many marks are lost by not following specific formatting or file-naming requirements. Always double-check your work before submitting.
    • 💡Tip 2: In written answers, use examples from your own experience or the course. For instance, when explaining online safety, mention a specific scenario like creating a strong password or identifying a phishing email.
    • 💡Tip 3: Manage your time during assessments. If you get stuck on a question, move on and come back later. Ensure you attempt all parts of a question, as partial marks are often awarded.

    Common Mistakes

    Common errors to avoid in your coursework

    • Over-manipulating images, making them look unrealistic.
    • Not saving work in appropriate formats.
    • Ignoring copyright and ethical considerations.
    • Using too many filters or effects that look unnatural.
    • Poor edge blending when combining images.
    • Forgetting to save working files (e.g., .psd) alongside final exports.
    • Saving final images in lossy formats (e.g., JPEG) for all outputs, resulting in lack of transparency when required or unnecessary quality degradation for editable masters.
    • Over-editing images leading to unrealistic color casts, excessive contrast, or visible halos from over-sharpening, which detract from professional appearance.
    • Neglecting to use layers, making edits irreversible and complicating subsequent changes or corrections.
    • Confusing image size (pixel dimensions) with canvas size, leading to unintended cropping or undesirable aspect ratio changes.
    • Using copyrighted source images without permission or proper attribution, which can result in plagiarism issues in assessed work.
    • Over-manipulating leading to unrealistic images.
    • Ignoring copyright and usage rights.
    • Misconception: 'Digital literacy is just knowing how to use social media.' Correction: Digital literacy involves a wide range of skills, including using productivity software, understanding cybersecurity, and evaluating online content critically.
    • Misconception: 'Programming is too hard for beginners.' Correction: Level 1 programming uses visual tools and simple logic, making it accessible. You don't need to write complex code; focus on understanding basic structures like loops and conditionals.
    • Misconception: 'Online safety only matters if you share personal information.' Correction: Even browsing can leave a digital footprint. Always use secure connections, update software, and be cautious of links and attachments.
