I have flirted with photography on and off for quite a few years; Only recently I decided I would invest the time really learn. Working in engineering and dealing with math all day, I don't see the technique part as being a challenge, but everything else is: We had family portraits made by a professional, which happens to be the friend of a friend, and what I found very interesting was her know how when it comes to scene composition, where and how to put hands, etc. She tweaked each scene a few times until everyone was doing the right thing and the results were great. It seems to me that learning the math behind photography is pretty easy, but the artistic part is where I feel challenged. Are there any good resources to learn about how to make good portraits? I found a lot of stuff on google which is either very vague or specific to one person, so I think I have to turn toward books. Any suggestions?
