How to use a photometer when shooting?

One is a data system and the other is a camera system, which are very similar in operation. \x0d\ Press the button, and the flash will inform that it has been started, which is very convenient to operate. When you start pressing, a lightning icon will change to another option, and it will be displayed as a reserved or other option. You should also know that some exposure triangles are composed of shutter speed, aperture size and ISO. These are the three modes in the camera, which can be set to automatic or customized. You need to set the menu mode in the studio, because you can't see the light in the built-in lamp, but the photometer can distinguish the speed of light, so you need to set the aperture size, ISO and shutter speed to use this device. \x0d\ 1。 For ISO, ISO 100 is generally used. Set a lower value that the camera can reach. Some cameras can only reach ISO200, so you can set the camera to ISO200. \x0d\ 2。 What needs to be set is the shutter on the camera. Both the camera and the speedometer know that the shutter speed in the camera is 200 seconds, so they are all set. \x0d\ 3。 Finally, the aperture size is set on the camera according to the balancer on the photometer. Sometimes you just want to read one of the lights, so you can put the photometer in front of the light instead of the camera, and you can get the value of this light, which is very good. \x0d\ In order to ensure that all lights can be tested, you should stand behind the lights and not be an obstacle. Sometimes it's really hard to choose a place. It can only be one way or another. Another thing is to make sure you face the camera.
