Artists often use the concept of time in their artworks to evoke emotion, tell a story, or highlight the passage of time. Time-lapse techniques involve capturing a series of images at set intervals to show changes over time, such as plants growing or the sun setting. Slow-motion techniques, on the other hand, involve capturing footage at a higher frame rate and then playing it back at a standard speed, creating a dramatic effect by slowing down the action. By incorporating these techniques, artists can manipulate the viewer's perception of time and create visually engaging pieces that explore the passage of time in unique ways.
