Find an image which has possibly been manipulated, attempt to explain both the process by which it was manipulated and why that photo may have been manipulated. Was the manipulation well done? May it not have been manipulated, but due to the type of image, was your expectation that it had been manipulated? Did the manipulation enhance or degrade the image? The impact of the image?
Tip: When describing the manipulation process, don't just say "Photoshop". After your introduction to the program and the readings, you should be able to speculate on some more specific details than just identifying that photoshop may have been used.
