Nice tutorial Armin! I've always admired your shots... and always checking out yours and the others in the other photo thread.
I've had a camera in my hands for over 20 years, and always learning. Everything you are talking about I learned in my high school photo class, but it is good to rehash it every now and then. At some point you don't really have to think about it much. Only a few years ago I acquired a decent semi SLR digital camera and renewed my love of photography, when I was younger and going to school, I had to hock my film slr and equipment and was without a decent camera for over 10 years. Last year I finally acquired a nice DSLR, something I've wanted to have for a long time. I'm achieving results that are making me very happy.
Being as I'm only an amateur and don't have much time to put into it, it takes a lot longer to start to master it.
Also, I've seen some great shots posted with some point and shoots, but composition is what really made them stand out.
