I want to take time-lapse photos of sunrise. What should I pay attention to?

5D3 is heavy. . . Time lapse photography? I don't understand you. Are you going to film yourself?

In terms of hardware, it is necessary to have a stable tripod and cable release (or use the silent photography mode of 5D3); Preferably a medium gray gradient lens.

In terms of parameters, spot photometry is used to measure the brightness near the sun, and surround exposure is used.

If you pay attention, arrive at the scene at least 30 minutes before sunrise, grab the position, set up the equipment and wait for the sun.
