Sony x280' s WT does not respond when pressed, so it can only be pulled in and out by hand in front, which is urgent.

First, interval shooting (in fact, it is the principle of time-lapse photography, which quickly presents a long process)

For example, when we shoot a documentary, in order to show some delayed scenes, we sometimes shoot the effects of sunrise and sunset, clouds rolling and clouds relaxing, and flowers blooming and falling. For example, the operation of general machines may be a little complicated, but the powerful interval time range of X280 is 1 sec -24 hours.

Next, let's take a look at the actual performance of interval shooting, and first briefly explain the test concept:

Shooting time selection: the light changes greatly at night, and the instantaneous effect of lighting and street lamps is obvious.

Shooting location selection: road overpass, traffic shuttle, deep sense, strong sense of scheduling, which is conducive to the test effect display.

Calculation in advance: It is estimated that the whole record is about 1 half hour (5400s, that is, the time required to turn dark during the day), so it is necessary to simply estimate the setting parameters. Finally, it was decided to record 1 frame every 5 seconds.

The calculation formula is: 5 (the interval is 5S)*25 (25 frames per second) *45 (the shooting sample is expected to be 45S)=5625S.

It is roughly matched with the expected 5400S, so that the process from day to night can be recorded roughly completely.
