* @example LookupTable_C.c
*
* @brief LookupTable_C.c shows how to configure lookup tables on the
* camera. It relies on information provided in the Enumeration_C,
* Acquisition_C, and NodeMapInfo_C examples.
*
* It can also be helpful to familiarize yourself with the
* ImageFormatControl_C and Exposure_C examples as these provide a strong
* introduction to camera customization.
*
* Lookup tables allow for the customization and control of individual pixels.
* This can be a very powerful and deeply useful tool; however, because use
* cases are context dependent, this example only explores lookup table
* configuration.
