There was strong contrast in this scene so I blended three exposures 1-stop apart in Photomatix. This produced a very striking colour image, but I preferred the gentler tones in this Efex conversion.
Camera at waist level and shot whilst I looked the opposite way. Processed in Analog Efex. If I only could own a single lens it would be the Canon 50mm f/1.2L
Canon EOS 5D Mark III, f/1.2 @ 50 mm, 1/2500, ISO 100, No Flash
I watched this gentleman for a while and came away feeling rather sad without
actually knowing anything about him. He seemed lost in his own world and it
didn't feel appropriate to disturb him.
A candid with the best lens I own, the Canon 85mm f/1.2 L II.
This is based on Bob's suggestion for a reworking of the image using an oval graduated saturation filter in Lightroom. I think it works quite well.
