5.4.3 32bit HDR generation: image mixing
Photomatix
This software is recommended for 32bit EXR generation. It is able to read 3x3 dng files
or unlimited size tiffs. It also contains very useful tools especially for outdoor images:
• Align source images - in case any external factor (wind, vibration on floor) moved the
camera from its position during image capture
• Reduce chromatic aberration at the edge of objects or buildings
• Attempt to remove ghosting artefacts - in case of non static scenes either for
background or object movement
• Process images by stripe allowing the processing of very big tiff files
5.4 HDR workflow (continued)
When using 1x1 image resolution, it is not possible to load the raw files
directly into Photomatix. In this case it is necessary to first process the
images in the Seitz Roundshot software and then load the tiff files in
Photomatix.
Please note that in this case, all conversion options must be turned off and
the S-curve needs to be set to 1. The less processing the image contains,
the higher 32bit image quality is generated.
