Lightroom Tone Curve Tutorial Notes

Introduction

  • Purpose: Demystify the tone curve in Lightroom
  • Goal: Make it simple, practical, and accessible

Understanding the Tone Curve

  • Basic Overview of Tone Curves:
    • Two gray curves: Adjust tones without affecting colors
    • Red, Green, Blue curves: Primary colors in digital photography
  • Explanation of Primary Colors:
    • Human vision perceives colors as red, green, blue
    • Cameras capture RGB light and screens display RGB pixels

How the Tone Curve Works

  • Image Setup:
    • Reset all tones in an image
    • Black (left) to white (right) representation
  • Adjusting Brightness:
    • Adding points on the line to adjust brightness
    • Dragging the left point up increases brightness, dragging right point down decreases it
  • Mid-tones:
    • Midtones are at the 50% mark
    • The diagonal line shows the relationship between blacks, whites, and mid-tones

Fine-Tuning with the Point Clicker Tool

  • Adding Specific Adjustment Points:
    • Use point clicker tool to add points for precise adjustments
  • Benefits of Using Tone Curves:
    • Allows for specific adjustments over broad ones (like highlights, shadows)
    • Chainsaw vs. chisel analogy (broad brush vs. precise tool)

Differences Between Gray Curves

  • Two gray curves serve different purposes:
    • First curve for quick basic adjustments
    • Point curve for specific area adjustments

Practical Examples

Example 1: General Adjustments

  • Adjust highlights and darks for better contrast:
    • Use the tone curve to refine image contrast without losing details

Example 2: Selective Corrections

  • Recover highlights and shadows selectively
  • Adjusting specific areas for better contrast and detail recovery

Advanced Tone Curve Techniques

  • Using RGB curves to selectively add colors to different tones
  • Example: Increase greens in shadows or reduce blues in highlights
  • Creating an S-curve:
    • A method to add contrast by lowering shadows and raising highlights

Color Correction Techniques

  • Combining tone curve adjustments with masks for skin tones
  • Adjusting skin tones for smoother and more appealing results
