Pictures and videos, both drawn and photographic, will play an important role in many courses. Modifying these pictures and videos will be pedagogically useful. For example, you could crop a picture to focus attention on a certain feature, or circle or label particular features. Using false color can help make certain aspects easier to see. Image enhancement is also possible.
