Ok I need some help here. My sister is a professional photographer and really wants to take the photos at our wedding. Problem is, she's also the MoH. (She's planning on handing the camera to an assistant for group shots she needs to be in.) I think she'll either be too busy taking photos to help when I need her that day or too busy helping me to get the shots I want. I also want her to enjoy the party and not have to work at the wedding. She's a phenomenal photographer so I know I'd love her shots so that's not the issue. I even suggested using a differently photographer and just letting her edit them but she says it would be easier just to take them herself. What do I do to keep it from being a chaotic rushing mess that day or hurting her feelings?
