Q1. What is a good image sensor? Why are the high-end DSLR cameras expensive?
Q2. What is the difference between optical and digital zooms?
Q3. Why did the apple make "stove-top" iPhone 11?
(Q4~Q9) Please explain and demonstrate the following functions/effects using your own images. Also, you can also explain when you change their values on a camera. Your answers are graded based on both the correctness and extensively considering various potential situations. Your answers do not have to be lengthy but should not be short. Note that you are allowed to use the DSLR images provided but you need to provide a suitable reason for why your smart phone camera cannot take the corresponding images. You can download the instructor's images from here.
