Photo Manipulation can be done very easily and in many different ways, from adding a speech bubble to someone’s head in paint to adding an extra eye in Photoshop. According to Lodriguss, 'with today's technology, we can literally do anything we want with images'. For example see the images on the right. Image 1 is of toothpaste begin put on a toothbrush, however when it gets on the toothbrush it ends up in a figure of a person. Image 2 has been manipulated so that the person's face has the texture and appearance that of cracked, dry soil. 
Image manipulation a controversy e-learning tool as it creates Ethics and Aesthetics issues (Lodriguss, 2006). Although it allows the learner to manipulate the photo the way that they require it, it creates images that are not entirely 'real'. Therefore having to give great consideration when using the image in a assessment piece.
