Utilizing HDR Effect

The HDR (High Dynamic Range) effect in iClone accurately represents the wide range of intensity levels found in real life high contrast scenes as result from direct sunlight and shadows.

Please visit USC - Institute for Creative Technologies Graphic Labs web site for more HDR resources.

Global HDR Effect

The HDR effect in iClone globally processes the light and shade strengths using two simple parameters, Threshold and Bloom Scale.

Fine-tuning with Tone Map

The high dynamic range image is passed to a tone mapping operator that transforms the image into a low dynamic range image suitable for viewing on regular displays. The strong contrast reduction phenomenon is resolved while the image details and color appearance are preserved. After you turn on the HDR feature, you may also fine tune the result to increase the dramatic effect by specifying the Gaussian Scale and the Exposure in the Tone Map section.

Using Glare

You can use the Glare feature to apply various lens effects to the project.

  1. Select a Glare Type from the drop-down list.

  2. Adjust the Scale slider to define the span of the selected glare effect.

  3. Note:

    • You may optionally adjust the values described above to prevent over-exposure of your scenes.

    • Please note that the parameters with blue names are key-able in different time frames.

HDR as Texture

If you have HDR images at hand, you may also load them into the texture channels (Reflection, especially) to create higher contrast and more impressive effects.
