Loren Nelson
Loren Nelson

After over 30 years in academics reality struck when Loren Nelson decided to travel and take photographs on a full-time basis. Retirement allowed this “journey” to begin late 2010 and the travel started in March 2011. He spent nearly two years traveling among the national parks and public lands in the US and Canada to capture the beauty and harshness of nature to share these images with those who have similar interests.

In 2012 Nelson moved to Jackson and this was the the birth of Natural Photography. Since then Loren has built a portfolio of more than 100,000 photographs and continues to capture digital images of wildlife and their scenic environment in Jackson and the great western states.

He became a founding member of the Teton Photography Group in 2013. His work can be seen at http://www.naturalphotographyjackson.com/

After enjoying 40 years of teaching motivation, learning, and interpersonal communications at Indiana University, I was looking for “work” in retirement. Joining the TPG to update my photography skills helped lift my spirits. And working with other amateur photographers through the Peer Mentor Program has really motivated me to help others as I improve my own photography. The Peer Mentor Program is a group of about a dozen advancing amateur photographers who meet together for a photo shoot and a critique every month. We work together to learn the technical and artistic aspects of photography, and we enjoy each other’s company. Read more about the TPG’s Peer Mentor Program at on this site, read my blog at FirstanAmateur.com, and contact me at risaacso@iusb.edu.

I picked up my first camera when I was a kid.  When I was in high school you never saw my face because there was always a camera up to my eye. I shot high school basketball games and pictures of logs and stuff like that.  After high school I put the camera down for over 25 years.  On a trip to the Galapagos in I was introduced to digital photography and in 2004 I bought a Nikon D70.  Digital photography was still quite new, and not very good.  Other the years I’ve shot more and more, and digital photography has gotten better and better.

Now I spend a lot of time traveling and making pictures.  I shuttle between Boston, Jackson Hole, WY and the New England coastline, and wherever the next airplane takes me.

I love making photographs and hope you enjoy looking at them.  Thanks for visiting.  www.mscpix.com

My lifetime journey into the world of photography began more than 45 years ago when my father brought home an amazing mysterious device.  A Bessler Topcon Unirex camera with a 50 mm lens and what seemed like a gigantic (135 mm) telephoto lens.  Holding that camera in my hands, I was instantly smitten.

Many things have changed, and my interest has waxed and waned over the years (waxing now) but my love for our hobby has always persisted.  The digital age and my affinity for computers allowed me to transition from film and B&W printing to digital photography.  In the late 1990’s dedicated film scanners (by Polaroid!)  and prosumer photographic ink jet printers gave us the first entry into the fantastic new world of digital imaging.

For anyone growing up with film, the digital realm is truly amazing.  Offering incredible touch up and correction tools along with easy full color printing at home that was unimaginable 20 years ago.  My imaging ranges from astrophotography, to landscapes, to wildlife, to architecture, to people.  All with the thought that prints are the ultimate expression of our art / craft.  Cheers! www.paulpodellphotography.com

Capturing the pure essence, beauty, and form of imagery through his lens and then hand-crafting that image into an exceptional print is the core of David Brookover’s art. His authentic, traditional processes for reproducing the original photograph include Platinum Palladium, Silver Gelatin, Photogravure, and Bromoil. In addition to Brookover’s focus on traditional techniques, the intuitive artistic detail in his wildlife, landscape, abstract, and western photographs make up the core philosophy of The Brookover Gallery in Jackson, WY.  www.brookovergallery.com

I was born and raised in the Central Valley of California. I love to travel and visited Jackson, WY on a road trip. It took about a year before I moved there for a job. Jackson’s been my home for about five years and I feel so lucky to be able to practice and refine my photography in the shadows of the Tetons. In my spare time, you can find me traveling around the area exploring with a camera around my neck. www.bethholmesphotography.com

I was drawn to photography by the images in classic magazines such as National Geographic and Life. The stories those images conveyed were very informative and powerful.  After college, I took a continuing education course in basic photography and purchased a camera. Unfortunately, a few years into a career in the tech industry, I gave up photography due to time constraints. 25 years later I moved from Texas to Jackson Hole, and the photography bug bit again. I enjoy taking black and white and wildlife, especially birds.  In addition, I also enjoy finding the unusual or abstract texture and shapes in both natural and man-made objects.

Rachael Dunlop

Rachael trained in analog photography immediately out of high school and went on to shoot bands in black & white, whilst working as a copywriter in advertising. Photography took a back seat in 2005 when she went to university to get a PhD in cell biology and she didn’t pick up a camera again until 2011, by which time everything had gone digital. She initially focused on birds, over time expanding her repertoire to other wildlife and some landscape.

Rachael is originally from Sydney Australia and has shot all over the world. She’s been in the Tetons since 2015 and spends as much time as she can in the field shooting unique wildlife like hummingbirds and grizzlies – neither of which she’d seen before coming to North America. Of the Tetons she says, “It’s a photographer’s paradise. It’s virtually impossible to take a bad shot here.”

I started my photographic journey very early in life shooting black and white with my brother.  When we moved to Connecticut our basement had the perfect room for a dark room, and we soon after invested in the basics to work with black and white film.  When we left that house my photography slowed to making images while traveling.  Moving to Jackson in the early 80’s reignited my interest and the camera got to come along on most hikes as well as the occasional bike ride or ski day.  I switched to digital in 2003 and continued to shoot around Jackson as time permitted and wherever my travels took me.  I now have more time to devote to photography and am trying to not only get out more but also to shoot with a purpose, I’m definitely still learning and hopefully also improving.
