3 In the Caustic and Global Illumination attributes adjust the settings to
the following:
Photon Intensity: 120000
Increasing the Photon Intensity increases the illumination in the areas
affected by Global Illumination.
To render the scene

the image.
2 When the image has completed rendering, click the Keep Image icon to

The brightness of the illumination in this image has increased as a result
of increasing the Photon Intensity. This is indicated by the increased
brightness and details seen in the shadow areas of the scene. However,
some circular spots have also appeared in the image along the dark wall
behind the bowl. These spots are the result of low photon quality settings.
Adjusting the quality of Global Illumination
The quality of Global Illumination is primarily affected by three attributes:
The accuracy of sampling (Accuracy)
The radius size that determines the size of the region surrounding a
particular sampling point (Radius).
The number of photons (Global Illum Photons).
