From whom should I look upon to learn

[Zakd]

Hi,
I'm regular visitor or this site and I mean every day. Although I do not post too much images since I'm big amateur and my photos are still too far away from the ones that are shown here.
I know that there is lot of different styles and different techiques in photography but in some way I think that I could look upon somebody or several photographers and to start learning from them taking into consideration that many of them have been studied and learnt some basics in schools.....
The bottom line is that you could suggest some of them that are standing infront of the others by their specific work.....
I would appriciate your suggestions
