There is a myth about that real photographers work in Manual mode 100% of the time. I have found myself working in Manual more and more over the years, but I firmly believe that when you are out for a walk with your lens that by understanding exposure theory and working in Av mode you will be able to react to unforeseen situations far more quickly if you are in Av mode than if you are in Manual mode. And there are times when I want to be in Tv mode and even times when I want to be in Program (Yikes!) mode. I am going to try and copy some posts from the thread here now. We shall see if I am successful....
IAC, feel free to share your thoughts. Should competent photographers work in Manual mode 100% of the time?
