Family
Choose five family members and decide who takes the lead, saxophone and three backing roles. Use separate portraits with a clear face and upper-body outfit for each person.
Friends
Pick a five-person lineup, agree on the roles, then collect a portrait each person is happy to use. Match the names to the role labels when selecting files.
Coworkers
Invite people to opt in and supply their own photos. Agree on where the eventual video will be shared; avoid taking staff-directory photos without asking.
