If you need to use flash, turn on the flashes for both cameras and expect things to come out a little weird.

如果你需要用闪光灯的话，把两部相机的闪光灯都打开，做好准备拍出的照片可能有点怪。

No matter how much I jack around WB, flash modes, self timers, and everything for each shot, the next time I turn it on for the next shot, it's right back at my standard settings.

不管我怎么调白平衡、 闪光模式、 快门定时器和为每次拍摄做的其他设置， 下次我开机拍摄的时候， 它总会回到我的标准设置。

It's refreshingly easy to use: just raise the flash head to switch on... then turn off again by lowering when the flash isn't needed.
