I currently live in Pacific Grove, California and have worked in 3D animation and TV production. I didn’t pick up a serious still camera until the spring of 2024 and have been hooked ever since.
My favorite photo genre is wildlife and I’ve been on photo safaris to Botswana and South Africa in the last couple of years. Both were absolutely amazing experiences, both educational and inspirational. Living on California’s central coast means I’m also lucky enough to have tremendously photogenic subjects like sea otters, sea lions and humpback whales within just few minutes of my apartment. I also scuba dive and have been learning underwater photography.
My camera gear is all Canon and I currently use DXO Photo Lab, Affinity Photo and Darktable for post-processing.
Ann Von Pentz
I am a fine art photographer based in Arizona and Montana.
My work is rooted in a deep appreciation for the overlooked and unseen. I seek out subtle character and emotional resonance within my subjects, revealing moments that feel both intimate and timeless. Whether following a well-worn trail or forging my own, I approach each photographic journey with curiosity and intention-allowing exploration itself to shape the images I create.
While living in Washington, D.C., I became interested in photography and started working with a mentor. Since relocating west in 2016, I have expanded my presence in the professional photography world. I have exhibited my work throughout Arizona at The Finer Arts Gallery, The El Pedregal Gallery, and the Terravita Art League, as well as the Desert Foothills Gallery. In Montana, my work has been shown in Bozeman at the Ridge. My photography has been featured in-and on two covers of-Images Arizona Magazine. I have also exhibited online with Artists in Arizona and the Online Catalog of Professional Artists (OCPA). This month I will be featured in Life + Style Magazine Scottsdale in a coffee table book.
I am a member of Nikon Professional Services (NPS), a juried member of the Sonoran Arts League, the Terravita Art League, an active member of the Phoenix Camera Club (PCC), and the Arizona Camera Club Council (ACCC), where I recently received Best in Show.

Cindy Marple
I am retired and living in the Phoenix area in Arizona. Photography has been a lifelong interest, starting with a Kodak Instamatic X-15 camera received for Christmas while in grade school. Nature subjects have always been the primary interest, starting with landscapes and flowers. When digital came along, it made it easier to pursue wildlife and birds, and today birds are my favorite subject.
I love to travel and have taken many photo tours and workshops over the years. Since I retired I’ve been able to do more of that, and have now visited all 7 continents. My favorite locations are remote polar regions, and more recently I’ve enjoyed the tropical regions of Central and South America where the bird life is incredible. When not traveling I spend a lot of time at a local Riparian Preserve photographing birds.
I’m an active member of several local camera clubs. I enjoy giving programs for photo clubs and local Audubon chapters, as well as judging for other local clubs.

I am retired and living the good life in south Florida. I have always had a love affair with the wilderness and the natural world. This naturally led to an interest in photography so I could bring home memories from my adventures. I have thus been involved in photography for more than 40 years and have worked as a semi-professional including work for the PGA and LPGA as well as shooting sports for various local colleges and have photographed over 800 weddings
My favorite photographic locations are Everglades National Park (the hardest place I've ever found to photograph), the Great Smoky Mountains and Rocky Mountain National Park. That said, I will go anywhere to get a good image. I enjoy shooting the Milky Way and the night sky, a real challenge, and I enjoy using long exposures.
I have taught photography on the college level, belong to several local camera groups and have served as a photo judge at local clubs and competitions. During the last 18 months I have had the honor of serving as a judge for some international photo exhibitions with affiliations to the PSA and have found this to be a most rewarding experience. My photos have been hung in the U.S. Botanical Gardens Hall in Washington D.C. and I have had several exhibitions in the South Florida Tri-County area.
I am a member of the online group called The Nikonians and shoot Nikon cameras currently using a D800 and D810. While I have a collection of Nikon only lenses my favorites are my 24-70 and my baby, a 200-400 f4 beast that weighs 7.3 pounds. My hiking buddy is my tripod that goes everywhere I do.
Butch Mazzuca, BPSA
I started shooting in 2008 after a trip to Africa and consider myself a generalist. I'm a retired insurance executive and former Marine Corps helicopter pilot :-) I hail from Chicago, now live in Tucson but spent the last 45 years in Vail, Colorado. I used to belong to several photo clubs but find PSA's Study and Discussion Groups more fun - plus I learn more.
My perspective on photography is as follows:
I believe if you ask 10 photographers to define what comprises a good photograph, you'll get 10 different answers. However, what the best photographer I know taught me, is that if you want to know what types of photographs most often win in competitions there's only one answer - "Impact, Visual Interest, and Storytelling are the three aspects of an image that need to be the hook that grabs and keeps the viewer's attention and outweigh any minor technical deficiencies."
It's also my experience that far too many club judges focus on the technical aspects of photography and overlook the artistry and creativity in a photograph. So, my reviews and visual feedback will focus on the foregoing.
Lastly, I believe post processing is 50% of digital photography and while I do not try to alter nature or a scene, I do try to reveal the strongest visual and narrative elements of a scene and review same way.

For almost 60 years, I photographed a multitude of outdoor subjects, especially wildlife. Over time, I used every major camera manufacturer's gear. I finally settled on the Nikon mirrorless system. Enhancing raw photos with Ai computer software gives me joy. Calling attention to our natural world is my passion.
All this makes life worth living.

David Kepley
David's father was in the military, so he was raised in many different places, but went to high school on the north New Jersey shore. He went to college at Gettysburg College and graduate school at the University of Maryland. While working at the US Forest Service over 40 years ago, he was inspired by one of his colleagues to take up photography. A trip in which he visited some of the great parks in the American west cemented his lifelong love of trying to capture the beauty and majesty of the natural world. After his retirement, David has taken a number of different classes and workshops to perfect his craft. He is currently first vice president of the Vienna Photographic Society. His works have been juried into Nature Visions Photo Expo for the past four years, as well as the Joseph Miller Abstract Photography Exhibit. His work has also won many awards at his photo club. A passionate devotee of our national parks, during the 2016 centennial year David and his wife visited 10 different parks, capturing thousands of images of them! He hopes that the sense of awe and majesty that he sees in the natural world will inspire you as well.
