Let's give you a detailed explanation of how the Canon 5DMarkII camera starts the exposure simulation settings when shooting in real time.Method sharing:Under Canon 5D Mark II "exposure simulation", the LCD monitor displays the image at a brightness close to the actual shooting result. If exposure compensation is performed, the brightness of the image changes with the amount of compensation.1.
IntroductionMost of the IO statistics tools under Linux, such as Iostat, Nmon, and so on, are only counted to the Per Device's read and write situations, and if you want to know how each process uses IO, it's a bit cumbersome.Iotop is a top class tool used to monitor disk I/O usage. Iotop has a UI similar to top, which includes information about PID, user, I/O, process, and so on.ExampleJust run it straight.IotopThe output is as followsTotal DISK READ
