"On average, most computer monitors have a specified contrast ratio between
500:1 and 1000:1, sometimes 1500:1. Current plasma displays are specified at a 10,000:1 contrast ratio (most are 50% lower). However, the contrast of commercial displays is measured as the ratio of a full white screen to a full black screen in a completely dark room. The simultaneous contrast of real content under normal viewing conditions is significantly lower. One of the only monitors that can display in true HDR is the BrightSide Technologies HDR monitor [

], which has a simultaneous contrast ratio of around 200,000:1 for a brightness of 3000 cd.m-2, measured on a checkerboard image. In fact this higher contrast is equivalent to a ANSI9 contrast of 60,000:1, or about 60 times higher that the one of a TFT screen (about 1000:1). The brightness is 10 times higher that the one of the most CRT or TFT. But such display should only be useful if it needs to operate in a pitch-black room and in two seconds under bright lightning, and the eye should be able to see a full dynamic range on the display in both situations."

I work a little with HDRI in using it to illuminate my 3D scenes, and recently got a digital cam and special tripod to go further in part for that. I imagine some of you on here might also work with HDRI, although it's still fairly new.
Incidentally, unbeknownst to me of its existence, I had made a request for a feature (for an open source program I use) essentially like this:

"poor 'man's" HDRI.
