25. Re: HDR Jun 25, 2005, 05:51 vacs
what is HDR?
do u need special kind of video card and monitor to witness this?can any one tell me about this without the tehcno jargon?

As I said in my previous post basic HDRL works with all PS2.0 supporting cards (DX9). High-precision HDR is however limited to GF 6x00 and GF 7x00 cards.

Concerning the need for a special monitor, actually yes, you do But those monitors which can display a much higher range of brightness are not publically available and very expensive. The problem with HDR indeed is that HDR offers too much precision for current monitors and that's where tone mapping comes in. This technique recalculates the rendered HDR image with brightness values which are more easily displayed on current monitors.

The get the best HDR experience you'll need a CRT monitor, LCD and plasma are much more limited concerning the high dynamic range they can display.
