I would not be too worried about a lack of photographs in a prospectus, a lot of what you would study will be analysis of photography. It has been the background reading that has given me greater understanding of what I am trying to create. I would not judge a photography degree until I had an interview/met the course leaders and looked around the facility. I chose my MA as the interviewers were challenging in their looking through my portfolio and I felt a real passion for the art. Of course having some cracking darkroom facilities was an important factor.
