There is an old saying, 'rules are for fools but provide guidance to the wise. ' We all have to learn the rules of any art before we are wise enough to know when to break them. I get the best results when I use the appropriate technique for the photograph that I want to take, that technique may or may not follow the rule book, but I've been taking photographs since 1958 so I probably do it all instinctively.
I am a firm believer that rules are meant to be broken. That said you have to fully understand them and understand why they are "the rules" before you can break it. People who take snapshots break the rules, but they don't know that there are rules.
Photographers know the rules, understand the rules and decide when the moment is right to break them.
Most often you obtain the best photos when you follow the rules. For some, depending on what you want to accomplish,like special effects, not following the rules works also.
Both. Use them as a guideline, but experiment and find your own style. A "good" photo is entirely up to the person looking at it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
