I'm a Hallmark alumnus who has been working in the photo industry since I graduated, but not as a photographer.
The school has changed a lot since I graduated in 1999, but the basic idea is still the same. It is a short program that focuses on photography fundamentals and the business of photography. If your daughter is planning on running a portrait studio it is a good place to go, if she wants to be an artist... not so much.
The problems with the school are the same as any other place, but maybe exaggerated by the lack of on campus student housing. If you daughter is motivated and has a good head on her shoulders, she will do well. But, if she is kind of lost and wants to party... well... she'll be able to do that.
What kind of things are you curious about?
