How to delay shooting sunrise with mobile phone

Delaying shooting the sunrise with a mobile phone requires the following operations:

1, simple understanding, time-lapse photography usually takes a long time to shoot a scene, and finally it will be played at a very fast speed. You can photograph a flower, the track of a car, sunrise and sunset, etc.

2. Time-lapse photography does not actually occupy memory. Let's make a small circle and record one. I thought it would take up so much memory.

Because time-lapse photography takes a long time, in order to ensure the stability of the picture, we need to fix the mobile phone.

1, about the fixation of mobile phones.

There is no place where I can put my mobile phone in the best observation position. Later, I found an empty and relatively high box to stand on the stool, and the mobile phone was temporarily fixed by the box+charger+wall. But because the box is too light, the phone may still fall down. I am extremely careful when operating my mobile phone in this state.

Improvement: I think it's still necessary to prepare a small tripod, and also look for other things that can stand stably at home, or improve the box again. Anyway, my method today is not feasible.

2. About the trigger of shutter key.

The shutter trigger of mobile phone shooting video, I learned it in the class of two-meter youth, but today I still used a very rude way to press the shutter button directly by hand. The correct way is to use the headphone cable to control it, because it is easy to shake the phone with your hands. I just found this problem when I started shooting. It is impossible to get a new earphone and plug it in.

Improvement: Take headphones when you go out in the future and put them in a conspicuous position at home. Shoot when you need to shoot a video.

3. About exposure locking.

Because the cloud is constantly moving, the brightness of the light I see from my mobile phone keeps changing. At first, the exposure lock was set, but after the sun came out, I found that the exposure of the picture was a little out of control, and the brightest place was all white and I couldn't see the details clearly. I quickly pressed the pause button, adjusted and locked the exposure again, so that in the final video, I would find that there was "light discontinuity" in the middle. I haven't found the cause of this problem yet. It may be that I chose the wrong position at the beginning of the exposure lock, or it may be for other reasons, but I think it is definitely impossible to stop in the middle.

Improvement: Re-learn the function of exposure locking in video, understand its principle, and "learn how to make initial settings in advance to prevent the light source from changing". When I understand this question, I will comment on the message. )

4. The status of the mobile phone.

I also want to talk about the current situation of mobile phones introduced by a young man of 1.2 meters, which I haven't met today.

1, remember to turn on the flight mode when shooting video, so as not to waste your effort before a phone call comes in;

2. Remember to fully charge your mobile phone.
