Valve om HDR og kommende "Lost Coast"

[KimmiK]

Meget interessant lesning, både for dere som allerede har testet teknologien i SCCT og FarCry, og for dere som det kiler litt i magen hos når det blir nevnt "Lost Coast"

“The ‘dynamic range’ of a scene is the contrast ratio between its brightest and darkest parts. A plate of evenly-lit mashed potatoes outside on a cloudy day is low-dynamic range. The interior of an ornate cathedral with light streaming in through its stained-glass windows is high dynamic range. In fact, any scene in which the light sources can be seen directly is high

dynamic range.” – Paul Debevec (this quote from Paul was given in the 3rd slide from the Power Point presentation which will be presented in full later in this article).

 

Other tidbits gleaned about HDR from the Valve presentation were as follows:

 

"A High-Dynamic Range image is an image that has a greater contrast range than can be shown on a standard display device, or that can be captured with a standard camera with just a single exposure. (from slide #5)."

 

"High-Dynamic Range rendering attempts to take an HDR image and produce a more realistic representation on a limited-range computer monitor. (from slide #6)."
