Summary
In this introductory lesson, students will learn the three fundamental elements of camera operation: aperture, shutter speed, and ISO, which are key to achieving proper exposure in photography. The lesson will explain how aperture controls the amount of light entering the lens and how it affects depth of field. Shutter speed will be covered to demonstrate its role in freezing or blurring motion by adjusting how long the sensor is exposed to light. ISO will be introduced as a tool for adjusting the camera's sensitivity to light, balancing low-light scenarios, and optimizing image quality. A digital lab component will allow students to practice these concepts using a camera simulation, where they can experiment with different settings and see instant feedback on exposure results. By the end of the lesson, students will be able to confidently manipulate these three settings to achieve well-exposed images in various lighting conditions.

Use the attached Lesson Slides to facilitate the following lesson. Begin the lesson by showing slides 2–4, which introduce the title of the lesson, the essential question, and the learning objectives. Emphasize that the essential question will be addressed throughout the lesson.
Next, display slide 5 and distribute the I Notice, I Wonder handout. Have students watch the video Camera Operations Demystified while completing an I Notice, I Wonder activity. At the end of the video, have students share some of their observations with the class. Remind students that the video introduces the three pillars of exposure (shutter speed, aperture, and ISO) as well as the four main camera types that will be used in this lesson (DSLR, mirrorless, camcorder, and webcam).

Display slide 6. Place students in small groups of 3–4 and have them conduct a Gallery Walk to interact with the four learning stations, each with a different camera body type. These stations should include Mirrorless, DSLR, Camcorder, and Webcam. Ask students to compare and contrast the types of cameras. Use the I Notice, I Wonder strategy as a way of generating student responses.

Transition to slide 7 and distribute the attached Card Sort handout and the Camera Operations Vocabulary handout to each student. The cards contains relevant words and definitions that students will need to complete the activity. Ask students to complete the Card Sort by matching words with definitions. Discuss answers as a class after students have had time to complete the Card Sort.
Extend
15 Minute(s)
Transition to slide 8 and distribute a copy of the Scavenger Hunt handout to each student. Engage students in a scavenger hunt using the Scavenger Hunt Notes instructional strategy. This scavenger hunt will include vocabulary, camera function icons, and camera body types. Place students into small groups again and have them take turns rotating workstations to gather information from each camera included. Invite students to find the corresponding buttons, abbreviations, and symbols found on each camera. Some workstations will require access to the digital menu.
Evaluate
5 Minute(s)
Display slide 9. Distribute paper and pens if needed, then ask students to complete a 3-2-1 reflection:
What 3 things have you learned today?
What are 2 questions you still have?
What is 1 thing you found interesting?
