3 Visually compare this rendered image with the previously rendered
images.
In this rendering, the shadow areas of the scene appear less dark as a
result of Global Illumination. The bowl also appears more transparent
than in the previous rendering.
The effect you want to achieve is to have the shadow regions receive
indirect light; that is, you want to be able to view more detail in the
shadow areas as a result of the Global Illumination. To do this, you must
adjust the Global Illumination photon attributes. After you change an
attribute, test render the scene to see the effect of this change in the
rendered image. These repeated test renderings or iterations allow you to
work systematically towards the goal of creating the desired final image.
In the next steps you use the Attribute Editor to increase the Photon Intensity
to increase the overall Global Illumination for the scene.
Increasing the brightness of Global Illumination
Increasing the Photon Intensity setting increases the brightness of Global
Illumination. The goal is to provide more visible detail and brightness in the
shadow areas of the scene in the next test image.
To increase the Global Illumination lighting
1 In the Hypershade window, double-click on the icon for spotLightShape1
to display the attributes for the spotlight.
2 In the Attribute Editor, click the spotLightShape1 tab to display the
lighting attributes for the spotlight.
