Select the menu View > Waterfall window to display the waterfall window. This window shows how a selected image line changes over time. For this purpose, the line at the selected cursor position is copied to the new window. With each new frame, all lines in the Waterfall window are moved one pixel down, and the new line is added at the top. This results in an image that flows from top to bottom and is useful for observing short-term image changes.
