High Dynamic Range Monitors

An anonymous reader writes, "We are seeing more and more about high dynamic range (HDR) images, where the photographer brackets the exposures and then combines the images to increase the dynamic range of the photo. The next step is going to be monitors that can display the wider dynamic range these images offer, as well as being more true-to-life, as they come closer to matching the capabilities of the ol' Mark I eyeball. The guys who seem to be furthest along with this are a company called Brightside Technologies. Here is a detailed review of the Brightside tech." With a price tag of $49K for a 37" monitor (with a contrast ratio of 200K to 1), HDR isn't exactly ready for the living room yet.

Monitors? .. What about input?

Since "true" HDR consumera camera's don't exist (anyone know?), it can be faked, quite convincingly, I might add.
i.e.
"It's a feature in Photoshop CS2 or Photomatix or FDRTools."

Even black and white can be support HDR. This is a great B&W example of why 8-bit greyscale just doesn't cut it.

Polaroid XR film

[dpbsmith]

I can't seem to find a reference to it online... I'd appreciate one if someone has one... but circa 1960 the Polaroid company developed a film for recording nuclear tests, which was similar to three-layer color film except that the three layers, instead of being sensitized to different colors, were given emulsions with widely different sensitivities. The fastest emulation was similar to Kodak Royal-X Pan, ISO 1600, and the slowest was similar to Kodak Microfile, and if I recall correctly had an ISO speed of something like 0.1

The result was to extend the useful dynamic range of the film by a factor of 10000 or so--more than a dozen additional f-stops of latitude, or extra Ansel zones, if you like.

The film was processed in regular Kodacolor chemistry (IIRC), each layer coming out a different color. In color, the result was a "false color" image displaying a huge dynamic range of light intensity; or, it could be printed as black-and-white using different filters to select different intensity ranges.

In effect, the photographer was automatically bracketing every shot by a dozen F-stops, in a single shutter click.

It was an incredibly neat hack. I wonder whatever became of it?
