DESCRIPTION

15       This program reads files defined in given  hdrgen  script  and  outputs
16       them  in  a  PFS  stream.  Each  frame  has a tag BV with corresponding
17       brightness value (APEX standard). Larger BV corresponds to  less  expo‐
18       sure (darker image), necessary to capture a bright scene.
19
20       The  generated  PFS  stream is to be used with photo-metric calibration
21       software and with generators of HDR images.
22
23       HDRGEN script file is a plain text file in which  each  line  contains:
24       <path_to_an_image>     <inverse_of_exposure_time_in_seconds>     <aper‐
25       ture_size> <iso_speed> 0
26
27       In most cases it is convenient to use the jpeg2hdrgen program to create
28       such a file automatically. In case it could not parse the exif informa‐
29       tion from jpeg files, it is necessary to  create  this  file  by  hand.
30       Below are the sample contents of such file:
31
32       <---  cut  here:  sample.hdrgen  /var/tmp/images/img08.jpg  4 2.8 100 0
33       /var/tmp/images/img09.jpg 58.8235 2.8 100  0  /var/tmp/images/img10.jpg
34       76.9231   2.8   100  0  /var/tmp/images/img11.jpg  322.581  2.8  100  0
35       /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen
