Let's shoot at night (please give the photographer advice)

Look at the machines. Some of them don't work. I haven't used D70s, and I don't know if this function is available.

There is a simple way to keep the characters from being dark. Use the slow door, about 1-3 seconds.

After pressing the shutter, ask the assistant to hold down the flash and press the next flash. Then close the shutter.

People get normal exposure through flash.

Due to long exposure, the background becomes blurred or dazzling. If the flashing light has this function, it will be simple.

Some machines flash once when pressed and once when closed, so people are overexposed.

And I don't approve of flashing lights on the top of the machine to shoot people. So it's better to flash.
