Bison, #Yellowstone National Park, #WY "I love taking images in inclement weather, showing animals in environments many will never get to see, nor want to experience. Tip - to avoid condensation: before bringing your camera gear inside pull your batteries, and cards, thereafter, place the camera gear inside a water repellant light-weight stuff sack and do not open the sack until the gear acclimatizes to the ambient room temperature. Note - the thin sack material allows the gear to warm faster than it would when placed in your camera bag." - charlesglatzer, #CanonExplorerOfLight Camera: #Canon EOS-1Ds Mark III Lens: Canon EF 600mm f/4L IS USM Aperture: f/7.1 ISO: 400 Shutter Speed: 1/640 sec
