We owe the name "Photography" to Sir John Herschel, who first used the term in 1839, the year the photographic process became public.Photography The word is derived from the Greek words for light and writing.

“Light makes photography. Embrace light. Admire it. Love it. But above all, know light. Know it for all you are worth, and you will know the key to photography.” -George Eastman

GPS Will we one day have magazines and newspapers made from paper thin plasma that show moving images rather than stills? Will there be a need for wedding photographers in 5-10 years? Should we start thinking more about video and its possibilities as we enter and delve further into the high tech, high definition digital age? Camera Phones

Film Tools enable you to convert a series of photographs into a light probe - a special image that represents the lighting environment in a room. You can then use the light probe to light virtual objects, so that the virtual objects actually appear to be lit by the light from the room. This technique is especially useful for compositing computer graphic objects into images of real scenes. Hollywood films use light maps extensively to blend CGI into a scene.

Panoramas Panoramas often have a wide dynamic range, i.e. one part of the panorama may contain the sun, another part may be in deep shadow.

Games A third use is in computer games. Recent computer graphics cards support HDR texture maps. With HDR texture maps, you can render objects using light probes, in real time, yielding much more dynamic and interesting lighting effects. "High Dynamic Range Lighting Effects" are used in many new high-end games.
