I am a native of Caracas-Venezuela, born and raised there. I still am a semiretired physician (Radiation Oncologist) and a self-educated photographer since the mid-sixties. As a teenager I was the youngest member of the Foto Club Caracas. Winner of the first price in black and white prints in all three camera clubs of Venezuela, the same year. Did my own black and white processing and printing for many years, until I finished medical school and came to the US for postgraduate training in the 70's.

After a very long gap, started with digital photography in the early 2000's and more involved since I acquired my first digital Nikon D300 . I am a "Nikonian" by conviction. Have participated in many competitions and received several awards.

I joined the first Camera Club in Florida in 2008: Broward Camera Club, of which I was President for four years (2013 to 2016). Also was a member of the Pines West Camera Club, and currently I only attend the Coral Springs Camera Club that offers activities of interest.

I joined PSA in 2011. Completed the course of Image Evaluation a few years ago, and most recently (March 2021) the Advanced Photo Travel Course and was an instructor for a while. Appointed as 2nd Vicechair of the PSA Photo Travel Division in 2021 as well as Director of all the Photo Travel Image Discussion Groups. Now I am the First vice-chair pf the PTD.

I am an active member on five of the PID Digital Dialogue groups: 04 (General Photography), 58 (street Scenes), 59 (Sport), 72 (Nature +) and now group 15 (Birds). I am the administrator of groups 15, 58 and 72. I am also a member of the PSA PTD (Travel Photography) group 04 and the PJ (Photojournalism) of Human Interest group 5 of which I am also the Administrator.

Early in 2022 I obtained my ROPA distinction QPSA, and in October 2022 my ROPA distinction PPSA. I hold 3 stars in Nature Exhibitions, 3 stars in Monochrome Class, 3 stars in Color Class, 3 star in Photo Travel Exhibitions and 1 star in Photojournalism.

Jim Horn Biography - I live in Oxford, PA which is within 8 miles of the Conowingo Dam Hydroelectric Plant on the Susquehanna River where there are 50 nesting pairs of eagles, osprey, ducks, and heron year-round. I am happily married to Linda who loves the same things and why we retired here. I have loved photography since college and always want to improve. I belonged to Tri-County-Camera-Club in Nutley, NJ and Baltimore Camera Club. I currently belong to Harford County Photography Group and Fair Hill Photography Group and am still learning how to improve the quality of my photographs. I recently retired as the pastor of West Nottingham Presbyterian Church in Colora, MD. I graduated from Princeton Theological Seminary in 1977 and received my Doctor of Ministry from Columbia Theological Seminary in 1993.

I retired last year after a career in journalism, followed by work in the non-profit sector. (Of course, some say journalism and non-profit are one and the same.) About half my time is spent on our family ranch in the Texas Hill Country where we raise angora goats (for mohair) and sheep (for wool). Many of my photos are from those environs.

My wife and I love to travel, primarily to New Mexico and the American Southwest. Those are other places where I love to shoot.

Although I've been photographing nearly my entire life, I'm at the point where I can devote more time and attention to developing the craft. A main goal of mine is to fine-tune my eye and improving my composition so that my photos stand out from appearing like snapshots. I am working very hard at self-discipline - slowing down, looking at various angles, composing the scene before shooting rather than my Click! Click! Click! rapid fire method.

Photography is great fun for me and a way to self-express myself. I have no illusions about being a professional. I shoot simply for the joy of it.

My equipment is rather low budget. I use a Canon T2i camera, various lenses -- mainly a 28-135 mm which is my "walk-around" lens - and the basic polarizing and ND filters. I also have a 400 mm zoom which I use occasionally for capturing shots of wildlife on our ranch. I do all of my processing on Lightroom.

Randy learned photography like many have, as a kid from his dad. A great gift he received for which he is grateful, and because of it he closer to his dad. Randy sees photography as a universal language that creates connection and relationships, and emotional responses that touches hearts. He is drawn to sharing photographs as he sees photography as a way to share the way he sees the world, and in also experiencing the photographs of others, he also he gets share a glimpse of their world too.

As a kid he dabbled and was intrigued with what can be captured in a picture - moments, art, and memories. In college he had access to a dark room and printed black and white pictures, and loved how the images magically appeared from just a white piece of paper. As he wanted to share photographs with others, he started a fraternity yearbook in his Junior year, and had it published for his frat brothers. Later it was marriage and kids, five of them. Well after the first few years, he found himself immersed in his career. But then he also came to the realization that there is more to life than work, so he decided to develop his photography skills. In 2014 he bought his first digital camera. The next logical step for him was to learn from others. So he signed up for a Shaw Nature Reserve course, and met Stewart Halperin and Jeff Hirsch, developed his relationships with them, learning much from their photography trips and tips, going to Venice and then Cuba. Most surprisingly to him, he loved learning the culture of other countries, and meeting the people he encountered.

Intrigued and excited with expansive possibilities, he also joined the St. Louis Camera Club, furthering his learning and sharing. It was from submitting photographs to competition with the intent to improve his pictures and learn what makes a good picture, he also got to see the world through the eyes of others. To further his skills, he started taking Kathy O’Donnell’s photo and photoshop classes. Randy won Camera Club Rookie of the Year for 2018.

Randy finds photography to be a experiential expression of his life, bringing to surface his insecurities and his gifts. He looks for a unique and different way to see the world (a different angle, a different view), looking for the unusual and the beauty of this world in its simplicity, in addition to its obvious magnificence. Randy practices law, owning his own law firm, spending many hours in his work, balancing the best he can his practice of law, and practice of photography. Growing up he never had a deeply seated dream, but photography changed all that. Now his dream is to share his pictures by creating a photo gallery where he practices law, rather than just having a "law office." And this he is doing. Always in awe in seeing and sharing the world through his photography eyes and from the photography eyes of others, he hopes and dreams to deepen that heartfelt emotional response and connection with others, delving deeper into that limitless expressiveness. For this he is grateful.

live in the Bay area of California and have worked as a scientist discovering safe medicines for more than 25 years. I recently took up the hobby of photography with a DSLR camera. I find birds to be challenging and interesting subjects for photography. But I am also interested in photographing landscapes and other wild life. I would like to learn about all aspects of photography from the group

I became interested in photography when I meet my husband forty-three years ago. Since then, we have belonged to many camera clubs and have competed in many competitions. Absolutely enjoyed attending the competitions where the judges actually critiqued the image and gave advise on how to improve. Started with film, slides, moved to prints and now digital but there is still room for learning. Shoot with a Nikon D500 taking nature, landscape, and whatever else catches my eye.
