How to set the sunrise delay parameter?

Select average measurement for the first measurement. First of all, the aperture depends on your preference. Turn it up if you don't want to shoot the light. If you want to shoot light, turn it to the minimum. Select aperture priority mode. Thirdly, set the ISO to the lowest level, the sunrise is getting brighter and brighter, so the shutter speed is definitely getting faster and faster. It's just as well. The lowest ISO can get a clear picture. Then the time depends on your estimated time. That's enough.
