A Dutch tilt is a camera shot in which the camera angle is deliberately slanted to one side. This can be used for dramatic effect and helps portray unease, disorientation, frantic or desperate action, intoxication, madness, etc.
The Dutch tilt is also known as Dutch angle, German angle, oblique angle, canted angle and even the Batman angle.
The Dutch tilt was used a lot in German films of the 1930s and 1940s. This is where the name German angle came from. The Dutch term is said to have been a mistranslation of the German Deutsch.
