It's a copy, but what is it?

On the other hand, the record of the shooting date and time, which is a very important factor for photos, has been very halfway.

To take a picture personally, set the camera at the time of taking the picture.The drawback of this method is that in areas where summer time is adopted, the same time is repeated when switching from winter to summer, and one hour of blanks can be created when switching from summer to winter.Also, you can switch immediately at your destination, but you may forget it and record the time of another region in the first few.When you return to Japan, you can forget to return the time.

In order to avoid this, it is better to set the unique time in the world, that is, UTC.It is a so -called agreement world.At this time, it will not be confusing if the time is calculated based on the time zone in the set place.

However, EXIF as a metadata standard in the photo records the time as an absolute one and does not record information in the time zone.It seems that some cameras record it these days, but it seems that it has not been used effectively.There is a time zone settings in the camera setting, which is the only time of the camera, that is, the time zone, just switching what time it is now.You need to record your own summer time or winter time.

Recent cameras have been somewhat convenient around here.For example, your favorite Nikon D5600 or D850 uses a smartphone app called Snapbridge and forwards images taken from a camera to a smartphone with Bluetooth.It has a function to resize to about 2 million pixels, and is useful, but this app is equipped with a function to incorporate the time and location information of the smartphone and embed it in photos.

As you know, smartphones have a function to automatically set the time information to yourself when you move around and lead to a mobile network.Therefore, the time of the smartphone changes as soon as the plane lands at the destination airport and unlocks the smartphone in -flight mode.If you connect the smartphone to the camera and take a picture, the local time will be recorded on the camera without manually changing the camera settings.With this, there is no disappointing mistake, and the camera accurately embeds local time and location information in photos.
