Answer: We can't do all the research for you, but here are a few ideas to consider: 1.) historical types: daguerreotype, tintype, pinhole
2.) Museums, people's homes, wedding albums, travel albums, magazine and internet advertising, billboards. . .
3.) Once you see the examples, you can describe the characteristics.
4. Example: The photographer arrives on the scene of an accident. Horrendous injuries, possibly people dying. Does s/he start taking photos right away? Or see if people need help? Call 911? Should s/he get permission to take photos of the injured? Will s/he make photos available to investigators, insurance companies, attorneys? Will s/he withhold disturbing (bloody, dead bodies) from publication?
5.) There is responsibility on the part of the photographer to make the product look as good as possible for his client. But it seems to me that painting, coating or otherwise altering the product so that it does not resemble what an average customer is likely to purchase is unethical. The photographer should use arrangement of the products, lighting, background colors, selective focus and camera angles to make the products look as good as possible.
Explanation: 2: I think your instructor needs to clarify their definition of media. It seems to me the term should be used to identify the production and publication of the photograph: negatives and paper, transparencies (slides projected onto a screen) digital, holographs, maybe others. The term in the question seems to mean "markets or niches" like sports, landscapes, architectural, commercial: fashion, products, advertising; portraiture: individual, group and family; documentary and news, etc.
