[Radiance-general] conversion of digital pictures to Radiance?

[Greg Ward]

Hi Barbara,

Mentioned on Axel Jacob's webpage 
(http://luminance.londonmet.ac.uk/webhdr/ as noted by Dr. M) is my 
application called Photosphere that enables one to manage and assemble 
HDR images from multiple exposures.  To facilitate camera-based 
photometric work, I have recently added a calibration feature to obtain 
more accurate absolute luminances from the resulting HDR images.  
Photosphere currently works only under Mac OS X, though I've been 
searching around for someone with sufficient talent and free time to 
port it to Windoze.  Photosphere (and the command-line version 
"hdrgen") may be found at my personal website:

	http://www.anyhere.com/

Output to Radiance as well as LogLuv and floating-point TIFF, and now 
OpenEXR formats are supported.  If you want some examples of HDR 
images, check out Erik Reinhard's website as well:

	http://www.cs.utah.edu/~reinhard/cdrom/hdr.html

I have a whole slew of HDR images I've created with Photosphere, but 
have not found a place to put them on the web as yet.

P.S.  Say "hej" to Oyvind for me!
