I love this post, and all the responses and I thank your question Peter.
I had a crisis with photography some months ago, and now I'm ready to say that because I love it.
Love has no answers but love itself. Can be crazy, can to has no sense, nor time or age, but you just can feel that thing inside of you.
It makes me to be a better person too. Like all the real love, of course, cause all real love starts for oneself. Taking pictures, you can be yourself at all, in esence, and being yourself and being with yourself alone, is when you realize who you are, and how to be better, how to eliminate those things and thinkings and fears or judgments that are not yours but are family or society things, cause in those instants you only hear your heart, nothing else.
I can stay a whole day taking pictures without food, or without sleep. Even stop feeling cold or time. The hours and minutes longer exist, there is only eternity and me.
I fully agree with Stig, particularly with this:
the import thing is the feeling. No one is forcing me to photograph, I don't compete with anyone, although I publish and like to receive comments on my work. The important thing is that I do it for myself!
I emphasize this sentence, cause the crisis to which I refer above has much to do with this, or even the issue of not being professional
Some years ago I started a relationship with a boy who was quickly "infected" by my passion for photography. But his passion was not heart but more material, I think. He started to study and practice a lot and to learn what a picture has to have, to be more commercial, cause his idea was to travel around the world and to live only with money from his photographs. So I found myself constantly with his judgment and a new opinion was set up in me and I went away from my heart and my own creativity, looking for a picture easier to sell.
An example might be stupid but really affected me, was about to take panoramas. I love the panoramic, and with the proportions that I want. I think that each image is created to be viewed in a particular way. But for him, only official proportions were correct, and anything that came out of that concept was criticized.
Fortunately this did not last long, my heart told me what I was doing wrong, when in a whale watching, one of my dreams fulfilled, was more concerned with getting a good shot that enjoy the moment.
Months after this, the relationship broke down, but it also broke my relationship with photography being during more than a year without touch a camera, until a few months ago, after a hard but beautiful travel to my inner, I'm back.
Now, like before all this influences, I'm sure that photography is an art to express yourself, to express your feelings, and I can finally enjoy again the euphoria of which many of you speak.
We are infinite beings, so there has not to be limits in our art.
I still remember when I was a child, how my mother got angry every time she went to the store to reveal the photographic film and she payed for a pictures of clouds. She used to tell me, are just clouds, why do you photograph it? But I kept doing for many years, as well as I will continue doing street photo, although she tells me every time she sees one of these images, I will be sued.
I realize that the magic of photography, as well as any art, is that somehow we capture who we are, and we must not be afraid to go through, to show it, nor should we judge, just enjoy it.
I may be wrong Peter, but I think maybe that feeling of violation that you get when you take a picture is a judgment about yourself. If so, then I said, do not judge, just enjoy it, be yourself.
Well, again, thanks for posting the question, and sorry for my English.
Have a beautiful day!
