Adding Photographic Touches in Post-production - Photographic Rendering with V-Ray for SketchUp - page 320

Note
Remember in V-Ray we had to use the sRGB button on the frame buffer window
in order to see how the gamma-corrected image would look. However, as the
sRGB button affects only the V-Ray frame buffer and not the final image, we
should be seeing the darker linear version that was rendered to disk.
The reason we get this visual discrepancy is due to one of After Effects' own default
settings. To see what that is and how it works, we will need to perform the following
steps:
1. Right-click on the Materials_Final.exr footage in the Project panel, and from
the Interpret Footage flyout, choose the Main option.
2. In the Interpret Footage dialog box that appears, select the Color Manage-
ment tab, where we will see the Interpret as Linear Light option.
This (as you can see) is set by default to ON for 32 bpc footage, meaning that when
After Effects detects that an image has a linear profile embedded (as all floating
point images should), it essentially applies an automatic gamma compensation to
