For the couple's wedding, Akira would be involved as he specializes in wedding photography. Since Akira and Hina share an assistant, Yumi, she will be assisting Akira during the wedding shoot. For the family portrait, Hina, who excels in portrait photography, will be involved. Yumi, as the shared assistant, will also assist Hina during the portrait session. Therefore, both photographers, Akira and Hina, will be involved with the couple's request, Akira for the wedding and Hina for the family portrait. Yumi, as their shared assistant, will assist both photographers in their respective shoots. Satoshi and his assistant Ken will not be involved as they specialize in nature and wildlife photography, which is not requested by the couple.
