During lectures, they constantly chatted in class. In a large lecture hall, most of the students chat loudly and the instructor keeps lecturing as if everyone were listening. It is a funny sight. No one seems to care about anything. However it's different at night.
Most students attending night classes are older, with daytime jobs.
The night students are more mature, focused, and have specific career goals. Most of them really want to become pro photographers. There are quite a few female students as well. This is surprising since professional photography is one of the most male-dominated fields in Japan. But in recent years, more females have been studying or entering professional photography in Japan.
