  In \cite{ManturovNikonovMay2023,ManturovWanMay2023} the author discovered a
very general principle (called {\em the photography principle}) which allows
one: a) To solve various equations (like pentagon equation) b) To construct
invariants of manifolds. The advantage of that principle is that it deals with
a very general notion of {\em data} and {\em data transmission} which may be of
any kind. In the present paper, we show that the definition of the
Dijkgraaf-Witten invariants of manifolds can be thought of as an evidence of
the above principle.
