Outline:

I. Introduction:

A.thesis:

· HDRI are the best images and file format to use when doing image based lighting for 3D modeling and animation. Their multiple layers of exposure make them a prime source for intricate lighting and maximum results.

II. Body:

A. History:

· The desirability of HDR has been recognized for decades but its wider usage was, until quite recently, precluded by the limitations imposed by the available computer processing power.

· Paul Debevec

· Radiance RGBE image file format

B. Synthetic:

· 1997 SIGGRAPH

· "Rendering Synthetic Objects into Real Scenes: Bridging Traditional and Image-Based Graphics with Global Illumination and High Dynamic Range Photography"

C. Tone Mapping:

· limited dynamic range

III. Conclusion:

· HDRI is one of the major advances in the digital world over the last few years and despite certain issues that still exist with compatibility or equipment for example, it still is the now and will be the future of quick, easy, yet great looking lighting, Image Based Lighting.
