Don’t believe what I, or any of your other photography teachers, tell you.
I’m not suggesting that we’re lying to you. We’re providing you with good information that you can use. The thing to understand is that our experience of photography is limited to our experience as photographers.
I think you should test whatever your teacher tells you by bringing whatever you learn into YOUR experience as a photographer.
This requires testing the information that you learn during class within the context of your own way of working as a photographer.
While you’re in my class I can tell you WHY I choose certain ways to meter and expose, but ultimately it’s in your best interest to find your own way to create a photograph.
I think that wide-eyed questioning, curiosity and exploration will serve you better than blind faith.
If it works for you who am I, or anyone else, to tell you that you should be doing things differently.
