A photo, also known as a photograph, is a visual representation of an image captured through the use of a camera or other imaging device. Photos are typically used to preserve memories, record events, and share experiences with others. They can be printed or digital, and can capture a wide range of subjects including people, landscapes, animals, and objects. In the context of the IELTS exam, being able to analyze and describe photos is an important skill for tasks such as the speaking and writing sections.
