I was on full green box to begin with and it was not working great for me. Met up with a bunch of friends here and all were moving buttons, changing lenses, putting filters on, resetting the aperture, etc. I was in awe of the fun they were having. So, I went to manual and haven't turned back. For me, I want the best exposure for the gear I have. I am a math teacher so I approach the camera as if the settings are offering me the perfect equation to solve my problem. I just have to decide how to get to that. Lots of fun, and makes shooting very logical and creative at the same time.
