4.2 Settings specific to Batch Processing
The “Settings...” buttons allow you to specify the settings for HDR generation, Tone Mapping,
and Exposure Fusion. Please refer to sections 2 and 3 for a description of these settings.
In the case of the settings for Generate HDR, there are a few settings that are specific to Batch
Processing and are described below:
Force Exposure Values spacing to:
The checkbox will force the EV spacing to the specified value. This option can be used when
the exposure information is not available in the EXIF data (or 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 will be ignored.
Source images are linear (no tone curve applied)
This option is intended for 16-bit TIFF files that have been converted from RAW files with a
RAW converter that allows the image to be left in linear space (note: very few RAW converters
allow this). Only check this option if you are 100% sure that the tonal values of the images are
linear relative to the values of light captured.
Note: the term “linear” may have a different meaning depending on the RAW converter. In
Adobe Camera RAW, for instance, linear is relative to the Adobe RGB color space and not to
the values of light, so you should never check this option with files converted with Photoshop or
Lightroom.
Process strip by strip
Check this option if the source images are large TIFF files. With this option, the HDR image file
will be 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 around
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.
4.3 Batch processing subfolders
When your bracketed series are located in multiple folders, they can all be processed in one
run, provided they are in subfolders of the same parent folder. To do that, check the “Process
subfolders” option at bottom of the “Source” frame on the Batch Processing dialog and select
“sequentially”.
When “Process subfolders sequentially” is selected, the batch will process the bracketed image
files in one subfolder and then move on to the next subfolder, all of which are contained in the
main parent folder.
When your bracketed sets are composed of varying numbers of exposures (for
instance, one set has three exposures and another five exposures), you can use
“Process subfolders sequentially” to combine the exposures in these sets in one run. To
do that, place each set in a separate subfolder, group the subfolders under a parent
folder, check “Process subfolders sequentially” and select “All” in the pull-down menu for
the number of images to process at a time.
If you are processing bracketed photos that will be part of a panorama, you may find it useful to
be able to organize your photos in such a way that all exposures of the same levels are under
