  • While I used to hate to include people in my landscape-focused images, ignoring the sense of scale and perspective they can bring to a scene is impossible. #sonyalpha
  • The fiery-throated hummingbird (Panterpe insignis) is one of the most colorful and beautiful hummingbirds found in Costa Rica. With the right light, the rainbow like colors that reflect from it's throat can be incredible! Sony a1 w/ 600mm f/4 GM #sonyalpha
  • One of my favorite places in the world for Astro Photography has to be Bolivia. Been the incredible landscapes, remote nature of most of my favorite locations and the insanely dark skies, photographing the Milky Way from this region of South America is truly an amazing experience in and of itself! Sony a1 w/ 14mm f/1.8 GM #sonyalpha
  • A Leopard cub climbing a tree during a passing rain storm. A sight I won't soon forget from a recent trip to South Africa. What are your favorite big cats? Sony a7R V w/ 400mm f/2.8 GM
  • After all these years, Yosemite is still one of my favorite parks in the US! Swipe left and let me know which of these shots is your favorite!
  • Happy Valentines Day! Nature is amazing! From Jaguars to Silverback Gorillas to Red Eyes Green Tree Frogs and even Fur Seals...love is in the air! Which one is your favorite? Swipe left to see them all! Sony a1 + a9II w/ mixed lenses #sonyalpha #valentinesday2023 #planetearth
  • I know I am not the only one that finds joy in the endless lupine fields found in Iceland! Even though they are invasive...they are still beautiful! Sony a7R III w/ 16-35 f/2.8 GM #sonyalpha #sonyambassador #sonypartner
  • One of the most amazing destinations for Astro Photography on the planet has to be Bolivia and the famous Salar de Uyuni. Home to the world's largest salt flats, this incredible dark sky location not only allows you to see more stars in the night sky than just about anywhere else on Earth...but if you time your trip right with the end of the rainy season, you can get mirrored reflections from the pooling water across parts of the salar. The end result...well...as you can see is beyond comprehension! Sony a1 w/ 14mm f/1.8 GM #sonyalpha #sonyambassador #sonypartner
  • There is always something magical about exploring Torres del Paine National Park in Southern Patagonia! I can't wait to be heading back down there in April to take workshop clients to my favorite spots throughout the park! Sony a7R V w/ 16-35 f/2.8 GM #sonyalpha #sonyambassador
