Photo shoot question?

It all depends on convenience. Two people who have jam-packed schedules and work far away from one another will probably meet for the first time on the set. If at all possible, the creative team (photographer, model(s), wardrobe and makeup specialists, etc.) will meet before the shoot so that everyone knows their respective roles and maybe provide some additional ideas for the direction of the shoot. In almost all of the photography sessions I conduct, I have met with the model and/or supporting team members days or even weeks before actually shooting. On a "Hollywood" scale, though, this is more than likely impossible with regard to how hectic celebrities' lives are. In the Lutz/Basalari shoot, I would be surprised if they had actually met prior to shooting.
