1) do you shoot following your heart, as in you anyhow adjust and if end up something nice, you'll just shoot.
You have confused making images "following your heart", and making images "anyhow adjust and if end up something, you'll just shoot".
Making images "following your heart" is one of the most difficult things to achieve in photography. Because it represent who you are and your personal world view.
"Anyhow adjust" is just that. "Anyhow adjust". A randomness in the way of doing things. There is a place for such a "method" of photography. It can incorporate a "heart feel" to what you decide to point the camera at with random "settings".
One is about the person, the photographer. The other is about the technicalities of image making.
Most people here will advocate learning the "fundamentals". Fundamentals may include techniques and " rules" of photography like composition, distortion, color casts, styling, etc. This is the "traditional" way of learning photography. Look at the curriculum on "basic photography" offered by SAFRA/PSS/SLCC. They all stress learning the "fundamentals", and there is obviously merit in this approach.
However leejay gave another viewpoint. He feels that one should start by "following your heart". In other words, take images which move you. Ignore the technicalities and "rules".
Now I hear people jumping in to say "you cannot break the rules if you do not know what the rules are!" This is the war cry of the "traditionalists". Now who is saying anything about breaking rules? If I start photography knowing nothing, and I do not what the "rules" are, what rules am I deliberating breaking? I cannot be breaking rules when the rules do not exist for me! I am not talking about traffic rules and things like that! I am talking about making 'art".
Is what leejay proposing something possible? Indeed so! Some one said that if one wish to shoot and shoot, just use a P&S. Well, he has a point. But why can I not use a DSLR as a P&S? Modern equipments are so good that short of unusual lighting conditions, making a decently exposed image is hardly the challenge. So use the DSLR as a P&S. Set it to "auto" mode. And photograph with your heart.
How about techniques? Are they not important? of course they are! Are rules not important? Of course they are! They are there for a reason. But let me tell you something. For hobbyists like you and me, the kinds of techniques we need to learn and "rules" to be aware of, are easy to learn! There are those who learn their photography in colleges and universities, and earn a diploma and degree, like BFA or even a MFA. These people usually set out to want to be a professional photographer, and it is imperative that they acquire all the skills necessary to prepare them for a professional career. But for a hobbyist like me, do I care? And regarding rules, just post your images here, and you will not be short of people telling you the rules you should be following.
I am rather limited in my photography. There are many things I do not know in photography. But frankly, for my photography, I do not care. It does not mean that I am ignorant of what is going on. And if there is something which I need to know, I will learn it.
How about leejay's assertion that concentrating on techniques might cause one to lose the passion? I am not sure about that. I think that is a very individual sort of thing. But what I have observed is that, for most people, concentrating on techniques and rules can trap them in the same mould of making images. Some people do have what it takes to break out of the mould. But I think the majority do not. Just take a look at the images in this forum, and decide for yourself if what I say have merti.
