Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

CUVPHI514A - Employ colour management in a digital imaging workplace

What evidence can you provide to prove your understanding of each of the following citeria?

Research history and apply theory of colour in a digital imaging context.

  1. Identify colour theories/theory as it applies to the digital imaging context using appropriate sources of information and standards.
  2. Evaluate currency/credibility of information gathered and ensure research scope is sufficiently broad.
  3. Examine how colour is created, defined and managed in contemporary digital imaging devices.
  4. Investigate the areas of capture, display, output and archive spaces in contemporary digital imaging devices where colour management is critical to the production of a quality product.
  5. Maintain accurate and comprehensive details of sources of information and standards.

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

ability to research colour theory and digital colour management systems/strategies

ability to evaluate and adapt appropriate digital colour management systems/strategies

ability to maintain and review digital colour management systems/strategies.

Context of and specific resources for assessment

Assessment must ensure:

access to appropriate technology and sources of information to research colour theory and digital colour management systems/strategies

access to an environment where a range of digital imaging devices and colour management systems can be applied

access to appropriate learning and assessment support when required

the use of culturally appropriate processes, and techniques appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by candidate

direct observation of candidate's evaluation, adaptation and management of appropriate colour management practices and strategies

case studies to assess candidate's ability to evaluate workplaces and their use of digital colour management practices and strategies

problem solving activities to assess candidate's critical thinking skills.

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.

Required Skills and Knowledge

Required skills:

research techniques sufficient to access information on colour theory and management

literacy skills sufficient to interrogate/interpret a broad range of information on colour theory and management

numeracy skills sufficient to understand numeric values and meaning against colour theory and how RGB, CMYK and LAB colour values are quantified

communication skills sufficient to:

critique and discuss colour theory and management

use industry and community networks as sources of information

critical thinking skills sufficient to identify best practice options and adopt/adapt colour management strategies

problem solving skills sufficient to:

recognise and resolve workplace issues when adopting/adapting colour management systems into digital workplace

solve colour issues

learning skills sufficient to seek expert advice when adopting/adapting colour management strategies

planning and organising skills sufficient to:

develop strategies to respond to future colour theory and management strategies

document research findings clearly and concisely

plan integration of colour management strategies into digital workplace practice

technology skills sufficient to coordinate the installation of colour management systems.

Required knowledge:

colour theories/theory and their application to colour management systems

commonly used research methodologies

current trends and emerging technologies in colour management systems

OHS requirements relating to computer usage.
