A picture taken portrays an emotion: sadness, happiness, loneliness, joy, or sorrow. Being able to capture these emotions will help the viewers connect with the photograph you have taken. Note that subjects that depict emotions is not only limited to people. You can also play with whatever you have in your home. There is no need of going out of the house. There’s already a lot to capture inside.
