Detects the naming scheme of the photos in subdirectories (ideally named by the photographer's name), extracts the date and time from the filename or metadata, and copies the photos to an output directory. The destination files are all named with the same date and time format and the name of the source directory.
The result is an output directory with chronological sorted photos, including the information who has taken the photo.
