-* `join(x)`: Join list of values with delimiter x, e.g. join(:): ['a', 'b', 'c'] => 'a:b:c'; the DELIM option functions similar to join(x) but with DELIM, the join happens before being passed to any filters.

      - A unique number for the photo based on its primary key in the Photos database. A sequential integer, e.g. 1, 2, 3...etc.  Each asset associated with a photo (e.g. an image and Live Photo preview) will share the same id. May be formatted using a python string format code. For example, to format as a 5-digit integer and pad with zeros, use '{id:05d}' which results in 00001, 00002, 00003...etc.
