Light Control
Light Control refers to the manipulation of luminance, color temperature, and intensity within visual media. In digital workflows, this encompasses global adjustments (exposure, contrast) and local corrections (dodging, burning, masking).
Core Principles
- Luminance Management: Adjusting brightness without altering chrominance.
- Color Temperature: Shifting hues toward warm (orange/red) or cool (blue) spectrums.
- Dynamic Range: Preserving detail in highlights and shadows.
Digital Implementation
Modern image editing software utilizes non-destructive workflows via adjustment-layers and masks. Key tools include:
- Curves & Levels: For precise tonal mapping.
- Gradient Maps: For color grading based on luminance.
- Selective Color: For targeted hue adjustments.
