Batch processing of photos - Printable Version

Code:

#!/bin/sh



# The post-processing script gets called after taking a burst of

# pictures into a temporary directory. The first argument is the

# directory containing the raw files in the burst. The contents

# are 1.dng, 2.dng.... up to the number of photos in the burst.

#

# The second argument is the filename for the final photo without

# the extension, like "/home/user/Pictures/IMG202104031234"

#

# The post-processing script is responsible for cleaning up

# temporary directory for the burst.
