thanks for your kind reply Dave. It is not so much a question of display
size but rather of range. Our computer screens and printers are for the most
part 8 bit devices. The true HDR image is a 32bit file. To display HDR
images on a computer screen it has to be compressed. That is where a
technique named tone mapping comes into use. Tone mapping preserves the key
image details and color while approximating the shadows and highlights found
in the original HDR image. At least that is the theory. Unfortunately in the
real world a good part of quality is lost along the way.

Svend & All,
Ausgezeichnet! That really is fantastic, Svend. At what resolution/size
does a monitor begin to degrade the enhanced quality of these images?
Tchus,
Dave

Some time ago there was a thread on this list regarding High Dynamic Range
Imaging in the genre of meteorite photography. I have recently experimented
a little with this matter and found the concept quite helpful when trying to
picture a certain meteorite as the human eye would see it. My results might
not yet be sufficient for the Pulitzer Prize, but as long as they don't add
a "best meteorite photo" category I won't consider to run for it anyway.

I have compiled a few images on my website:
