What gear do you use?
I carry two bodies, the Canon EOS 5D Mark II and 7D, and up to four lenses. My go-to lenses are Canon's 17–40mm f/4L and 70–200mm f/2.8L zooms. Since I have to hike to locations, I use a Lowepro Nature Trekker bag. I always use a Gitzo carbon-fiber tripod in low light. Most of my work is in natural light, but I use two Canon Speedlites for fill. I use a Singh-Ray Vari-N-Duo variable neutral-density polarizing filter that takes up to 8 stops off the exposure, so I can use a slow shutter speed (even in bright light) and create more impressionistic images. I love working in low light and bringing in intentional camera movement and slow exposures.
