Hi friends, am a student in a film school which has a quick 6 month cinematography program. I am attending classes regularly. As the course is just for 6 months the subjects are thought very fast.and,it is very tough to clear doubts with professors der due to my language problem with them. so , i am trusting this forum to clear my doubts.So , how stupid or silly my question is kindly help me:)

My question is


WHAT IS A "EXPOSURE VALUE",HOW TO FIND IT?,IS IT REALLLY IMPORTANT TO KNOW THIS "E.V" WHY?
