Last week, we have talked about the depictive level of photography, flatness, frame, time, and focus. We also talked about how photographers use lenses to create a new world that is close but also apart from the real world. In this chapter, we are looking at how photographers come up with the idea of their worlds and how do they present them to the viewers. I feel personally connected to this chapter because I have always been interested in psychology and the ideas and thoughts behind a piece of art are something worth looking into, and this chapter also includes how we operate in a psychological way, mental refocus of things we saw, and the neuroscience behind it. Thank you for the interdisciplinary of studying at Hamilton College, I am able to connect my photography class to my psychology class. Everything is constant at a certain point in time, but we still observe them differently because our perspectives are different. The perspective we often talked about has little connection with the physical level of things but is deeply and mentally connected to the person who is looking at it. People have different perspectives because of their experiences, cultural background, emotional state, education, and etc. Perspective makes the diversity of art. When we compose a photo, we see the things we want to see and either leave the things we do not want out of the frame or hide them behind some other object. Photographers communicate and present their world to the viewers via photography. They often focus on the point they want to stress and obscure other things. One thing I have noticed among the example photos provided in this chapter, photographers often focus on a black space to open up the space in the picture and increase the depth of the mental space of the photo the viewers may feel, opposite to using white to create a shallow mental space.
