Compare and contrast Pictorialism, Modernism, and Postmodernism.

1) Compare and contrast Pictorialism, Modernism, and Postmodernism, including their similarities and differences, when they occurred, what their primary objectives where, what visual characteristics they embody, and your opinion of each. Also, for each movement, give an example of a photographer whose work would be considered exemplary of that style and include your reasoning for each choice.

2) Compare and contrast these two images. Address style, form, composition, and content, and for each image, name an artist who likely could have made it, including your reasoning for making that choice. Also, be sure to be opinionated, specific to image details and develop context to critical ideas and movements we have studied.

Solution-Diagram of a small region of tardigrade dna helix

In an attempt to mimic the ability of tardigrades to survive space radiation, your research lab is working on protein coverings that could potentially protect vulnerable DNA molecules from space radiation.

a) Draw a diagram of a small region of tardigrade DNA helix that is at least partially surrounded by a protective protein. While your diagram does not need every detail, be sure that it makes the [withheld] very clear.
