I like to think that photography is just light, a combination of different intensities of it. And colours are just light, being absorbed and reflected by everything, in different ways.
Being a good photographer means knowing how to perfectly control and understand light under any circumstance. It's not about the place in where you are, or how good your camera is. No excuses, everyone can learn photography.
Graphic design, image composition and edition are not different, it's all about modifying,that colours, that light. That's why I believe that, nowadays, we can create anything that we want, and thats why I love so much this world. If you can imagine something, you can create it.
I'm very far away of mastering all this. But I see that, little by little, I'm learning how to do things that I'd never imagine I would know.
