Identify images belonging to an image-sequence.

None.

HDR_FUZZ

Two images are considered part of a sequence, if their DateTimeOriginal-values (or ModifyDate if DateTimeOriginal is empty) differ at most HDR_FUZZ seconds.

HDR_LIST

List of all images, with all images of a sequence on a single line separated by commas. HDR_LIST defaults to $IMG_DIR/hdr-list.txt.

IMG_DIR

Work-directory. Defaults to $TARGET_DIR/work. This module scans all files in the work-directory with the current IMG_PREFIX and IMG_EXT.

This module uses a simple heuristic to identify image-sequences: images taken in quick succession (at most HDR_FUZZ seconds apart) are considered to belong to an image sequence. This heuristic is far from perfect. In the future, there will be other more sophisticated methods available, e.g. a module could take advantage of additional exif-information like exposure-bracket mode or even the sequence-numbers some cameras add to the exif-data.

It is probably a good idea to check the generated list-file and correct any wrong sequences manually.
