One of the type of photos that a lot of people will love is portrait, which basically means that you shoot people. But it can be difficult and requires a lot of deep thoughts on how to do it.
One way to make a good one is to shoot people for what they love. When the object person is doing what they love doing—eating, sleeping, reading or playing sports, they will usually be the most charming.
It is also good to capture the moment that the object is enjoying.
