Read the first 7 Digital Workflow & Color Management flashcards as text

  1. In a raw workflow, what does a camera manufacturer's 'standard' picture profile affect?

    Answer: The JPEG preview embedded in the raw file and the demosaiced rendering in converters that honor it

    Picture profiles alter the embedded JPEG preview and influence rendering in software that reads them, but the underlying raw sensor data remains unchanged.

  2. What is metamerism in the context of color printing?

    Answer: Two colors that match under one light source but differ under another

    Metamerism occurs when two color samples with different spectral compositions appear identical under one illuminant but different under another, a common problem with inkjet prints.

  3. Which Delta-E formula is considered the most perceptually uniform and is preferred for evaluating color accuracy in modern profiling?

    Answer: Delta-E 2000 (CIEDE2000)

    CIEDE2000 applies corrections for lightness, chroma, hue, and their interactions to align numerical color difference with human perception more accurately than older formulas.

  4. A digital imaging specialist sets Photoshop's working CMYK to 'U.S. Web Coated (SWOP) v2'. This setting affects:

    Answer: How CMYK values are interpreted and displayed when no embedded profile exists

    The working CMYK space defines how untagged CMYK files are interpreted and how Photoshop displays CMYK color values on screen.

  5. Which workflow step ensures that a digital file's color will be correctly interpreted by every application in the production chain?

    Answer: Embedding an ICC profile in the file

    Embedding an ICC profile tags the file with the color space definition, so every color-managed application knows exactly how to interpret and display the image data.

  6. What is the primary function of a LUT (Look-Up Table) in a digital imaging workflow?

    Answer: To map input color or tonal values to output values, enabling fast color transformations

    A LUT defines a pre-computed mapping from input to output values, allowing complex color grades or transformations to be applied quickly and consistently.

  7. When evaluating a monitor's calibration using a colorimeter, a Delta-E result below which value is generally considered 'excellent' for professional color work?

    Answer: Below 1.0

    A Delta-E below 1.0 indicates a color difference imperceptible to the human eye, which is the target for professional-grade monitor calibration.
