Pathos: The ad shows the people's responses to the pictures he was showing them. The actors in the ad had a positive emotion, which gives off to the consumer. It also added humor and everyone loves a little laugh.
Ethos: It is using Ashton Kutcher, a famous actor, showing credibility and showing that the product is reliable. Tbh - I'm the type of person that would buy that camera because Ashton Kutcher used one.
Target: This ad could target people interested in photography, interested in just buying a camera, or maybe target people with higher income levels because nice cameras aren't cheap.
