projector with an LCD display with it's backlight "hinged" out of the
way, a la the original paper by Seetzen et al:</p>
<p>Seetzen, Helge, W. Heidrich, W. Stuezlinger, G. Ward, L. Whitehead,
M. Trentacoste, A. Ghosh, A. Vorozcovs, "High Dynamic Range Display
Systems," ACM Trans. Graph. (special issue SIGGRAPH 2004), August 2004.</p>
<p>For my own use, I still have the HDR viewer I made over a decade ago:</p>
<p>Ward, Greg, "A Wide Field, High Dynamic Range, Stereographic Viewer," Proceedings of PICS 2002, April 2002.</p>
<p>By far the easiest (and cheapest) solution for still images is to
print out a grayscale version of the square root of your image (with
maximum normalized to 1.0) as described in the above paper, but as a
large-format print. I would make this one the image with exaggerated
contrast, since you can print it at high-resolution. Then, project the
original image divided by this grayscale image using a standard DLP or
LCD projector -- preferably a bright one although it doesn't need to be
high-resolution, onto this print. Line it up, and violá! You have a
high-resolution, high dynamic range still image. There's no way to make
it move, sadly.</p>
