Please film the video in a shaded area during the day. Avoid direct sunlight, as it will cause severe overexposure and make the video unclear.

Also, please turn on your phone’s flash while recording the video.

How to turn the flash on when recording?

Turning on the phone’s ultra-wide-angle camera does allow you to record a wider field of view, but please do not do so.

Because we only need its shape and size, and do not need to know its detailed textures.

Please record the video in horizontal (landscape) mode.
Horizontal videos help us clearly see the entire area.
