Next year, in college, I'm hoping to get an intern spot with a local photography group. They specialize in portraits (like school shots, sports, family, modeling, etc.). What is the key to a good portrait shot? After my year or two, or maybe 4, what kind of equipment would I need to look at getting. Rolling with a Nikon D60, Nikkor 18-55 and 55-200mm (need a better lens yes?) and a SB-600.
