This repository contains code for converting between RADIANCE rgbe
HDR image formats and TIFF, JPEG, and PNG files.  The programs are
support routines for the deva-filter workflow.  Somewhat similar
functionality is provided by the RADIANCE ra_tiff program.

The software can be built on either Linux or MacOS.  A Windows version
can also be cross-compiled on Linux.  Pre-compiled Windows binaries are
in radiance-conversion/Windows-binaries.

---------------------------------------------------------------------

To make a displayable version of a RADIANCE HDR file, try:

    rad2jpeg --autoadjust input.hdr output.jpg

If you need to make exposure adjustment, try:

    rad2jpeg --autoadjust --exposure=+1  input.hdr output.jpg
			or
    rad2jpeg --autoadjust --exposure=-1  input.hdr output.jpg

    Increase or decrease the exposure adjustment as needed.
