In my opinion I believe that Ethnography is going to involve with a lot of observation by studying someone in the own environment , such as observing someone or face to face interview . but  It may also  depend on who or what your observing. Ethnography may also involve you to watch the person every move especially if there is a connection between your self and the thing that you are observing, and putting everything at the end into your own words and how it is related to you.
