In high dynamic range rendering (HDRR or HDR rendering), also known as high dynamic range lighting, is the rendering of computer graphics scenes by using lighting calculations done in a larger dynamic range. This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with the more simplistic lighting models used.
Graphics processor company Nvidia summarizes the motivation for HDRR in three points: bright things can be really bright, dark things can be really dark, and details can be seen in both.

Famous quotes containing the words high, dynamic, range and/or rendering:
“What generous beliefs console
The brave whom Fate denies the goal!
If others reach it, is content:
To Heaven’s high will his will is bent.
Firm on his heart relied,
What lot soe’er betide,
Work of his hand
He nor repents nor grieves,
Pleads for itself the fact,
As unrepenting Nature leaves
Her every act.”
—Ralph Waldo Emerson (1803–1882)
