It's that we can't teach you in a paragraph or two. These are all nice people - and we need to see it to help you. You have to practice and get comfortable with all the nuances (lighting - aside from the atmosphere- has many ways of changing the look of everything) it's not as easy as it looks. You have to play. Even if you're a natural talent, you still need to learn the tools. You have a lot of information - some of it is questionable. Things can get mixed up real easy. Ask 1 question at a time - you'll get the right answer. Post a small pic here, so we can help.
