"If you want to change your photographs, you need to change cameras. Changing cameras means that your photographs will change. A really good camera has something I suppose you might describe as its own distinctive aura." -- Nobuyoshi Araki

A very meaningful quote, from a good friend.

I've a few cameras and I've just come to realize how correct Araki san is. My style of photography is different when I use a different camera.

At the end of the day, it's not the any system or format is superior. they are just different. Our preference for one over the other is simply a reflection of our mood at the time of choosing :-)
