Dry for wet is a film technique in which smoke, colored filters, and/or lighting effects are used to simulate a character being underwater while filming on a dry stage. Fans and slow-motion can be used to make hair or clothing appear to float in the current.

When you start to scrutinize these conventions, you'll find that, often, they are used to shape how we think about a character or event. When it comes to characters, conventions can easily turn into stereotypes.
