text: There are some really high speed cameras out there that have been used in things like nuclear testing.\n\nFor the automotive industry the best application i can think of for high speed cameras are crash testing so that they can view the crash at a very slow rate to see exactly what happened to the dummies.  One thing i remember from when Anti-lock brakes first came out is that they used high speed cameras a lot to show exactly what was going on with the wheels.
