I recently became more aware of Richard Avedon's life and work, and ordered a DVD documentary about him, which I found very interesting. There is no way he will displace HCB for my attention, of course. Avedon shot with larger-format cameras, and his shooting was mostly in studios and other controlled settings, which is not the equipment I (currently) use, nor the environments in which I shoot.
