4.1.2 Batch Processing Settings
Use the Settings buttons to access HDR generation, Tone
Mapping, and Exposure Fusion settings. Refer to Sections 3
and 4 for a description of these settings.
The following settings for generating HDR images are specic
to batch processing:
• Force Exposure Values spacing to: Forces the EV spacing
to the specied value. This option can be used when the
exposure information is not available in the EXIF data, if
two or more images have the same exposure information,
or to force the EV spacing in all cases. In the latter case, the
exposure information in the EXIF data is ignored.
• Source images are linear (no tone curve applied):
Intended for 16-bit TIFF les that have been converted
from RAW les with a RAW converter that allows the image
to be left in linear space. Very few RAW converters allow
this, so only check this option if you are sure that the tonal
values of the images are linear relative to the values of
light captured.
• Process strip by strip: Check this option if the source
images are large TIFF les. With this option, the HDR image
le is created in several passes, processing and loading
only one strip of each image into memory at a time. One
strip is composed of a limited number of rows set to
not exceed approximately 512 MB of RAM. This option
is particularly useful when processing large panoramas.
Note, though, that the alignment functions are not
accessible when the “Process strip by strip” option is used.

Note
The term “linear” may have a different
meaning depending on the RAW
converter. For example, in Adobe
Camera RAW, linear is relative to the
Adobe RGB color space and not to the
values of light. Therefore, do not select
this option with les converted with
Photoshop or Lightroom.
