Photography and Image Manipulation

Guiding Questions:

What should a photograph look like?

Why might someone want to alter, change, or edit a photograph? What is the goal?

What are the ethical considerations regarding image manipulation?

Time- 1-2 class periods with optional extension activities

This collection includes images related to the topic of image manipulation and artistic photography, and includes a lesson plan for teachers as well as images and students activities related to media literacy across the curriculum. The collection of images and articles is designed to facilitate conversations around how and why images might be manipulated and for what purpose. Discussion questions and thinking routines allow for students to critically analyze the images as whole group and in small groups to consider why and how a photographer or artist might alter an image. Extension activities and resources are also included.

Day 1:

Warm Up/ Engagement:

What should a photograph look like?

Have students do a think-pair-share together addressing the question. Alternatively, this could be done as a silent chalk talk.

Debrief as a group.



Why might someone want to alter, change, or edit a photograph? What is the goal?

Have you ever altered or changed a photograph? How? Why? (Think Shapchat, Instagram, Photoshop, etc.)

Is it ever a problem to manipulate a photography? Why?

As critical viewers of media and images, students should always consider the audience and purpose of photographs. For example, an artistic photograph doesn’t have the same audience or purpose as a journalistic photograph.

Explain to students:

We’re going to look closely at the work of two photographers (Jerry Uelsmann and Robert Weingarten) to see how photographers might manipulate their images (digitally or otherwise), why they might do this, and the effect it has on the viewer.

Close Looking:

Lead students through a discussion of one of Uelsmann’s images by looking closely at one image as a group using the Visible Thinking routine, “See Think Wonder.”

Discuss the photographer’s likely message, audience and purpose of the image. Then have students consider how Uelsmann might have created the image.

Then, read an article about Jerry Uelsmann in Smithsonian Magazine, “Before Photoshop.”

Debrief the article and have students journal on their reactions to Uelsmann’s quote, “The camera is a license to explore.”

Alternatively, students can read and discuss the article,"Photography Changes What We Think 'Reality' Looks Like."

Have students share responses with the group as a closing activity.

Day 2

Warm-Up: Recap learning/connections from last class.

Explain that in today’s class we’ll consider the work of another artist and photographer, Robert Weingarten. Weingarten’s work is a “non-traditional” form of portraiture. Before looking at his images, have students brainstorm their ideas on what is a portrait. Students could engage in the 3-2-1 Bridge Routine on this topic.

Close Looking:

Lead students through a discussion of one of Weingarten’s  images by looking closely at one image as a group using the Visible Thinking routine, “Zoom-In.” After looking at the image as a whole, have students consider the image as as whole using the “Connect-Extend-Challenge” routine.

Weingarten’s portraits of Colin Powell and Celia Cruz are linked in the collection.

Discuss the photographer’s likely message, audience and purpose of the image. Then have students consider how Weingarten might have created the image.

After discussing the image, watch the video about Weingarten’s process.  

If time allows, group students into small groups to visually compare/contrast the works of Uelsmann and Weingarten on chart paper.

Exit Ticket:

How do these photographs change your understanding of photography and what can be done with images?

I used to think…

Now I think….

Possible Extension Activities:

Have students create a composite image (surreal landscapes or portraits)  inspired by Robert Weingarten or Jerry Uelsmann with their own photographs and Photoshop.

Have students explore other historical images that have been manipulated (intentionally or unintentionally) that are included in the collection.

Article on historical image manipulation from the ClickIt Exhibit

Have students look at the ethical issues in digitally manipulating photographs

Have students consider other ways in which the evolution of technology has influenced the images we create.

Using Agency By Design, a design thinking framework, have students complete the following activities:

Parts-Purposes- Complexities Routine-- Digital Camera

Take-Apart Activity w/ digital cameras/analog camera

Have students research different topics in the history of photography including camera obscura, daguerreotype process, Muybridge and moving images, and Kodak.

Planetary Topography

Students get an introduction to the concept of topography and how topographic data are displayed with graduated colors. Students practice visualizing and translating map-view data into side-view topographic profiles of various features. Then, with this background, students examine real topographic data from four planetary bodies in the solar system and interpret this data to answer questions about each planetary body. 

Students will:
  • Understand that topography is a 2D representation of a 3D feature, the elevation of a surface.
  • Read and analyze topography data to find what’s high and low in elevation.
  • Visualize the shape of a land form or feature based on its topography.
  • Interpret real planetary topography data to answer questions.
  • Explain how topography data is useful, both on Earth and other planets.

Planets of the Solar System

Through this collection, students will deepen their understanding of each planet in our solar system.  Pairing the See, Think, Wonder thinking routine with an embroidered quilt of the solar system will pique students' interest in the dwarf planet, Pluto.  After discovering the year that the quilt was made, students can explore the website to learn the history of Pluto.

Using the provided websites, students will work in groups to research a planet.  They will use the obtained information to write a headline that captures the most interesting aspect of the planet and to create a model of the planet.

Plesiosaurs and other Large Marine Reptiles

Explore this complementary collection of materials for the Smithsonian Science How webcast, Plesiosaurs and other Large Marine Reptiles with Paleobiologist Dr. Laura Soul. 

Travel back in time with Paleobiologist Laura Soul to learn about the giant marine reptiles that once ruled the sea, like plesiosaurs. Laura will introduce your students to several related groups of marine reptiles, like pliosaurs and elasmosaurs, exploring their unique features and adaptations for living in marine environments. Laura will also share some of her while research and discoveries about how the body shapes and sizes of these marine reptiles changed over time. Throughout the broadcast, Laura will take questions from your students via text chat and there will be opportunities for students to share what they think using live polls. Join here on April 11 at 11am and 2pm ET:

Prehistoric Climate Change and Why It Matters Today

In a lesson in this issue of Smithsonian in Your Classroom, students do the work of a team of paleontologists studying a time of rising carbon dioxide and rapid global warming during the Eocene epoch. By examining fossils of tree leaves, and then incorporating the findings into a mathematical formula, they are able to tell average annual temperatures 55 million years ago. Really!

Preventing the Dodo: Unveiling Animal Conservation Stories

What stories do the animals on the American Trail at the Smithsonian's National Zoo tell? Students will use the Project Zero Global Thinking Routine Unveiling Stories to uncover and consider the complexity around conservation. I asked students to consider more than just what is the initial story. I wanted to know what they thought the human and world stories might be. With the success of these animals I wanted students to also consider what the new and untold stories that might remain. The Unveiling Stories thinking routine is a great way to explore the complicated stories of the gray wolf, bald eagle, beaver,  North American river otter, and wood duck. #goglobal
