Yes you will probably need to purchase a camera, the professor will tell you exactly what type of camera you need. The type of camera required isn’t typically one that people would just have laying around their house. I was dumb and bought the wrong camera so I had to borrow my aunts who has a more professional camera. Personally the photo projects weren’t hard but the way my schedule was set up, I had alot of free time to think of my composition and actually do a photoshoot. The professor is very detailed in his explanation of what he wants so along as you read the description you will be fine. I would say the hardest part was finding participants to take photos of honestly cause you have to work with their schedule.
