5.4 HDR workflow (continued)
5.4.3 32bit HDR generation: image mixing (continued)
Seitz Roundshot software
Press the „HDR" button in the „Parameter" menu to activate the „HDR" tab:
This menu allows to merge differently exposed images of the same scene into a single
32bit EXR file. The input files must be in DNG format.
The Seitz Roundshot HDR mixing tool is able to process all dng file
resolutions. However it does not contain any ghost removal or image
alignment tools.
Therefore it is recommended to use this tool only for static scenes (mainly
indoors). For the outdoor scenes please use Photomatix or other HDR
mixing tools (Photoshop for example).
Avoid changing the lens aperture from one image to image because:
- The camera can move slightly creating a misalignment between images
- The depth of field changes between images
- The aperture information is not written in the metadata and has to be
corrected manually. This can be done by readjusting the exposure time
in a metadata editor like PhotoMe.

Press "Browse" and select a set of
differently exposed images of the same
scene.
All the parameters necessary for the HDR
generation are stored in the image
metadata (except for aperture. see hint
below).
Click "Generate". The mixing of the 32-bit
HDR image takes a few minutes,
depending on image size and number of
images. The progress of the mixing process
is indicated by a percentage progress bar.
A 32bit EXR file is saved according to the
selected image saving path.
