Overview

Tone Mapping is a post-processing technique that converts high dynamic range (HDR) values into a displayable range, ensuring that rendered images appear natural and visually balanced. By adjusting brightness, contrast, and color, tone mapping helps avoid overexposed highlights or overly dark shadows, resulting in a more realistic image.

Components (Table)

• Enable / Disable

  When enabled, tone mapping is applied to the rendered image so you can see the effect of the selected method. Disabling it shows the raw rendering result without any tone mapping applied.

• Exposure

  Exposure controls the overall brightness of the image. Raising the value makes the image brighter, while lowering it darkens the scene, helping you correct overexposed or underexposed renders.

• Saturation

  Saturation adjusts the intensity of the colors. Increasing saturation makes the colors look more vivid and lively, while decreasing it creates a muted or grayscale effect, allowing you to control the mood and style of the render.

  This dropdown menu allows you to select the algorithm that defines how HDR values are mapped to the display range.

  Exponential produces a smooth roll-off in highlights to reduce harsh clipping.

  Uncharted2 uses the curve from the game of the same name, offering cinematic contrast and balanced mid tones.

  Hejl **is designed for real-time rendering, preserving highlights and maintaining a natural look.

  ACES follows the Academy Color Encoding System, giving a filmic appearance with accurate color and wide dynamic range.

  Khronos Neutral provides a balanced, predictable curve suitable for technical previews and consistent results.
