Questions about taking a masters program. Help :)?

Im just finishing up my bachelors degree in International Business Management. I absolutely hate business (so i have figured out) and realized I love writing and photography and travel. Im thinking about taking a masters in journalism or communication. Is this possible to do within a 2 year period, or will I have to start over? How does it work with masters, since i wont be taking a masters in economics or anything related to business. Any advice would be GREATLY appreciated!
