Hello

Hello: It is the abbreviation of photo and メール. It originally refers to sending picture files through email. It was later cited that at some fan meetings and photo sessions, specialized staff were responsible for taking photos, and then the photos were sent to the audience who took photos with the stars via email. Before the advent of smart phones, due to the pixels of mobile phones and the fact that some selected viewers did not have mobile phones or mobile phone camera functions, the staff used to use professional digital photos to take and mail them. Now, most people use smart phones. The people directly asked the staff to take pictures with their smartphones without having to go through the camera. Nowadays, writing sessions are equivalent to photo sessions and video sessions.

There will be a photo session, and the selected candidates will participate in the photo session.

For reference only.
