What should I pay attention to when holding a delayed mobile phone?

1, try to use a tripod if you have one. If you don't have a tripod, put it on a fixed object nearby, such as a window sill and a railing. Hand-held shooting is prone to jitter and the picture effect is not ideal.

2. Cancel the off-screen function of the mobile phone regularly, which may stop shooting.

3. Turn on the flight mode of the mobile phone, otherwise it will be wasted if a phone call comes in during shooting.

4. Pay attention to the power of the mobile phone, especially in summer and winter. Mobile phones consume power quickly. If it doesn't work, plug in a mobile power supply.

5. Pay attention to the calculation of shooting time. The minimum frame rate of general video is 24 frames per second, which requires at least 24 frames per second, that is, 24 pictures. Time lapse photography also follows this method. If you want to take a time-lapse photo of 10 second, you need to take 10*24=240 photos. If every photo is 2 seconds apart, you need to shoot continuously for 240*2=480 seconds, which is 8 minutes.
