Schlieren and shadowgraph photography is an imaging technique
that can be used to visualize air flows and thermal plumes.
It allows us to see what was once invisible but always
present in the sensation and perceptions of discomfort or
comfort. Once again - we don't feel the heat loss from
the building, we feel the heat loss from our bodies and this
is controlled by such factors as the
mean radiant temperature.
