You can edit your registration via the link in the registration confirmation email. Check the box for a friend photo if you want one to be taken, and save the changes. Please make a change before the shooting date. It is a good idea to write wishes about your friends and siblings on the form as well, if possible. There is no need to give a separate permission to shoot photos of friends and siblings, as their permission to shoot is generally included in the shooting permission given in the registration.
