pfsinhdrgen - Create a pfs stream with different exposures defined by hdrgen script.
SYNOPSIS
pfsinhdrgen <sample.hdrgen>
DESCRIPTION
This program reads files defined in given hdrgen script and outputs them in a PFS stream. Each frame has a tag BV with corresponding
brightness value (APEX standard). Larger BV corresponds to less exposure (darker image), necessary to capture a bright scene.
The generated PFS stream is to be used with photo-metric calibration software and with generators of HDR images.
HDRGEN script file is a plain text file in which each line contains: <path_to_an_image> <inverse_of_exposure_time_in_seconds> <aper-
ture_size> <iso_speed> 0
In most cases it is convenient to use the jpeg2hdrgen program to create such a file automatically. In case it could not parse the exif
information from jpeg files, it is necessary to create this file by hand. Below are the sample contents of such file:
<--- cut here: sample.hdrgen /var/tmp/images/img08.jpg 4 2.8 100 0 /var/tmp/images/img09.jpg 58.8235 2.8 100 0 /var/tmp/images/img10.jpg
76.9231 2.8 100 0 /var/tmp/images/img11.jpg 322.581 2.8 100 0 /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen
EXAMPLES
pfsinhdrgen sample.hdrgen | pfsview
View exposures defined in sample.hdrgen script.

dcraw2hdrgen - Parse information in given Digital Camera RAW files and output a hdrgen script for generation of HDR images.
SYNOPSIS
dcraw2hdrgen <file1.cr2> [<file2.cr2>...]
DESCRIPTION
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 doesn't 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.
EXAMPLES
dcraw2hdrgen IMG_0001.CR2 IMG_0002.CR2 IMG_0003.CR2 > sample.hdrgen
Creates a sample.hdrgen script for given images.
