By imaging a laurel leaf at 3 min intervals and by subtracting the difference between the images to see where an embolism formed, we were able to determine at which water potential laurel leaves cavitate. Images were colorized by how much time had elapsed and combined to give a complete picture of the plant’s response to water stress.
