What types of photographs generate the most emotion in the viewer? We have a new photography service for brides and need input.

We will introduce a totally new service for the brides and weddings market. We need to create posters that communicate emotionally with our showroom visitors, especially brides. The posters will be used to inform and advertise. They should stimulate conversation about the idea and concept. We are unsure whether we should select an image created through graphics-style or a real bride photo. We are considering graphics so our posters will be consistent with other marketing. (Also, it is easy to do.) However, we also think a real photo is better at stimulating emotion. Please, advise.
