Flasher and flasher trigger; The equipment I am using now is Canon 650D. Recently, I want to add some equipment to improve it and prepare to put it into the lamp.

If it is 560, the light can flash, that is, the top light flashes, and the flash can be set in a good position without external flash. If the requirements are higher, you can add an external flash, and one set is enough. In other words, one lamp is connected with a flash lamp, and other lamps flash with light. Cable release is wired and remote control is wireless. If I have to control the shutter by myself, if I am restricted by the position, or if I have to shoot the remote controller, it is better to shoot other objects by cable. The cable release is not affected by the angle and excess light, but by the distance; Also, if the remote control and camera have the same style and channel, someone else's remote control may also open your camera shutter. Door b is door b, which is used for long exposure. Press and hold after opening, and close the shutter after releasing. There are not many kinds, let alone which one to use.
