I recently realized i have a passion for photography. It makes me really happy taking pictures of the world and creations of god and people and how they all are of a work of art. I'm almost 100 percent sure this is what i want to do for my career and I'm 15. I want to be the best of the best when I'm older. Anyone have any tips of what i can do now to prepare myself? Can anyone direct me to where I can learn about f-stops ISO, shutter stops, light, composition, ETC?
