This document discusses two methods for capturing images and video on a computer - using the Snipping Tool or Microsoft Paint. With the Snipping Tool, the user selects the snipping mode, chooses an area to capture, and saves the image. With Paint, the user takes a screenshot using the Print Screen key, pastes it into Paint, crops the image, and saves it. The document notes that both methods default to saving images as PNG files and encourages practicing screen captures before moving to video capture software.
