Hi. I am wondering if it is typical for a second shooter at a wedding to be paid or if it is the norm for these positions to be non paying and more for experience and portfolio building? I ask because I have the opportunity to shoot 4 weddings as a second shooter, but there is no pay involved. It's just for experience and port building. Should I continue to look for a second shooting position that will pay at least some sort of cash compensation? I have been involved in photography for over ten years, currently I consider myself semi - professional, but have NO wedding photography experience. Your thoughts?
