Photography is what you make of it. What you see in the viewfinder can be ugly. Your heart can barely resist the horror of what you see or your eyes become blurred by pity and shame. But it's all reality and you have to know what to do with it. I do not think anyone could advise you how to learn to use reality, except by telling you to always be honest to yourself, but this is rather vague. Of course you can not interpret what you see in your viewfinder and you can not take a good picture without having first understood it. You must be able to feel a certain affinity with what you are photographing; you must be a part of it and at the same time remain sufficiently detached to be able to see it objectively.
