Media Literacy is the ability to read a picture and "consist of a series of communication competencies, including the ability to ACCESS, ANALYZE, EVALUATE, and COMMUNICATE information in a variety of forms, including print and non-print messages." (Definition Source)
It's important to understand the many different ways pictures communicate to us. According to this article, angle, framing, light, focus and composition are just a few ways pictures communicate to us. The Mid-Continent Research for Education and Learning Corporation (McRel) has created standards by which our students from grades K-12 should exceed. For example, middle school students (grades 6-8) should "understand how symbols, images, sound, and other conventions are used in visual media". (McRel Standard 9) For example, students should comprehend the concept of the sound of brakes from a car and a loud bang insinuates that there was a car accident.
As educators, it's important that our students understand how to interpret and analyze photos, videos, etc. Our world is continually changing and our students have to adjust to these changes in order to be successful, literate adults.
