"Photography is my medium to learn more about the world and myself. Strangely, as my understanding grows, the mystery and a sense of shock and wonder deepen.
Of course, a multitude of things can be expressed through photography. For me, a main concern is to show some of the perennial and extraordinary beauty of life on this ravaged, raped and polluted planet that, despite us, still grows flowers every year, as well as highlighting the contradictions caused by our impact on it and each other. I would consider a photograph successful if it either raises questions in the viewer, or passes on at least some of the immense joy and gratitude I experience through photography."
Chinch Gryniewicz

...and some more quotes which are relevant to my work by other photographers:

Photography records the gamut of feelings written on the human face, the beauty of the earth & skies that man has inherited, and the wealth and confusion man has created. It is a major force in explaining man to man.
Edward Steichen

The camera doesn't make a bit of difference. All of them can record what you are seeing.
But, you have to SEE.
Ernst Haas

I never question what to do, it tells me what to do. The photographs make themselves with my help.
Ruth Bernhard
