This program can be used to automatically create an hdrgen script for
use with software creating HDR images. The exposure information is
extracted from RAW files using the dcraw tool.
If this script doesnt recognise the exposure settings from the images
taken by your camera, please verify if dcraw supports your camera:
dcraw -i -v your_image.cr2. You should see a detailed information on
shot settings including exposure time. Maybe compiling the newest
version will help.
