What's the point of photography homework?

If you make a documentary, you can travel in the streets and take the life of family, mother, son and beggar as the theme.

The works of migrant workers are mainly black and white, with high contrast and small depth of field, and promotional videos are generally used for urban construction to help the poor.

Maybe that's all I can think of. You'd better be more specific.

I can also take a sample for your reference.

In fact, the above themes can be filmed, even with a home card machine, you can also shoot the feeling of a documentary.
