When you submit a picture taken with your iPhone to a public office or school

The iPhone’s camera is not only easy to shoot, but also high ly. These days smartphones compete for camera performance, but they also feature advanced features such as Deep Fusion, which applies machine learning to improve the image quality of photos in pixels, and “Smart HDR”, which expresses a more natural difference in light and dark.

It is such a camera function of the iPhone, but be careful when submitting a photo somewhere. Depending on the system of submission, maybe the photos taken with the iPhone may not be accepted.

The cause is “HEIF”, which was adopted from iOS 11. HeIF(High Efficiency Image File Format) is a format for storing still images and videos, and the image quality can be kept at about half the size of the traditional -jpeg- data format. Apple products such as iPhone and Mac, as well as Windows 10 will be available if you get a free extension.

However, the penetration rate is low compared to JPEG, and it is likely not to be treated as an image format. In fact, overseas, there are reports that students uploaded photos taken on their iPhone as answers to online exams, but failed the exam….

In order not to get caught up in such trouble, it is a safe choice to set the format to JPEG for photos submitted to government offices and schools. If you open the screen in “Settings” → “Camera” → “Format”, and select “Compatibility Priority”, subsequent photos will be saved in JPEG. However, the pace of storage consumption per photo will increase by about twice, so let’s return it to “high efficiency” so that it is taken with HEIF when the errand is finished.
