If you take a photography class, it’s not enough to simply put in your time during the class.
A good photography class will give you information related to the class topic, but to have what you learn in the class sink in you’ve got to apply what you learned to your work outside of class.
If the instructor gives you homework, you’ve got to do it.
Learning photography is experiential.
You can sit and listen to all the lecture that you want but the learning process is incomplete without you applying what you learn in class to your work outside of class.
