Film noir is also known for its use of low-angle, wide-angle, and skewed, or Dutch angle shots. Other devices of disorientation relatively common in film noir include shots of people reflected in one or more mirrors, shots through curved or frosted glass or other distorting objects (such as during the strangulation scene in "Strangers on a Train"), and special effects sequences of a sometimes bizarre nature. Night-for-night shooting, as opposed to the Hollywood norm of day-for-night, was often employed. From the mid-1940s forward, location shooting became increasingly frequent in noir.
