Adjust apertures, shutter speeds, and camera focus based on a combination of factors such as lighting, field depth, subject motion, film type, and film speed. Determine desired images and picture composition, selecting and adjusting subjects, equipment, and lighting to achieve desired effects. Estimate or measure light levels, distances, and numbers of exposures needed, using measuring devices and formulas. Soft Skills: Critical Thinking, Judgment and Decision Making, Reading Comprehension Accommodations for Learning Differences It is important that lessons accommodate the needs of every learner. These lessons may be modified to accommodate your students with learning differences by referring to the files found on the Special Populations page of this website.

Ask students how that effect was achieved. Explain to students that shutter speed is one of the three different parts of the photographic triangle. Ask students the following questions to students and discuss their answers: Why is it so hard to get a good, non-blurry shot at a football game at night?

Explain to students that shutter speed is one of the three different parts of the photographic triangle and is used to determine how “fast” any given exposure is. different. Make sure that if a Then, go through the slide presentation with students. Discuss the following: I: General Overview a. What is shutter speed? b. Measuring shutter speed II: Shutter Speed and Light a. Longer shutter speeds lets light in for a longer amount of time b. Faster shutter speeds let light in for a short amount of time III: Shutter Speed and Motion a. Longer shutter speeds will blur motion b. Faster shutter speeds will freeze motion IV: Aperture and the Human Eye a. Correlations between aperture and the human eyeball V: Review their shutter speed. student has a camera different than the one shown in class, they also know how to adjust Remind students that when shooting images with longer exposures (anything slower than 1/60th”) they will need to utilize a tripod.

Teacher will model for students the proper camera handling techniques. The instructor will demonstrate how to change the shutter speed on the DSLR in both shutter speed priority (“TV”) and manual (“M”) modes. Give small groups of students a DSLR to work with and have students adjust the shutter speed on the cameras in various modes. Encourage students to pay attention to the resulting changes in light and motion in their photos after adjusting their aperture. The teacher will observe students while working and reteach if needed. Independent Practice After going over the slide presentation, do the following: Divide students into groups of three or four. Give each group a camera with a memory card (if students have their own memory cards, this is even better). Instruct students to take two photographs: o One photograph should exhibit a motion that has been frozen using a fast shutter speed. o One photograph should exhibit the same motion that has been blurred using a slower shutter speed. For this one, students will most likely have to utilize a tripod. Instruct students to set their DSLR to either manual mode (“M”) or shutter speed priority mode (“TV”). Students should be given approximately 30 minutes to complete the task. After the task is completed, students should upload their photos to a shared folder where the instructor can view all of the photographs. Ask students to explain how they went about completing the assignment. During the discussion ask students if each team member was used effectively take a photo with a shallow depth of field.

Review talking points and key terms from slide presentation. Ask students what they would adjust on their cameras if they needed to freeze motion. Ask students how they would adjust their shutter speed if they wanted less light in a given exposure. Ask students how they would adjust their shutter speed if they wanted more light in a given exposure. Ask students how they would adjust their shutter speed if they wanted to freeze motion Have students assess and critique their own work and other students’ work. Evaluation Informal Assessment Any or all of the following may be used as informal assessments : Instructor Observation Question and answer Instructor will discuss and reteach where needed. Formal Assessment Frozen and blurred motion photographs will be assessed using the rubric (attached). Students may also be assessed through the shutter speed quiz and quiz answer key. Enrichment Extension Students are also encouraged to take their own light painting or stair trail images using long exposures and tripods. Copyright © Texas Education Agency, 2014.
