I remember shooting a film camera in my twenties. Then I came back to shoot digital about 10 years ago. I find huge technological advances in the camera industry these several years and the post processing maneuver is jaw dropping because I did not know much about dark room in the old days. Showing my photos to others is easy nowadays because of the media but is also apprehensive to me, as I find so many good photos in the Flickr or Instagram. About a month ago my friend in Canada suggested me to join the PSA and he is a member for many years. I hope I can learn from you.

I became interested in photography 60 years ago when I received a chemical set for a birthday present. My darkroom graduated from my bathroom to a permanent structure in my parent's garage.

Born in South Africa, I was able to combine my love of nature and wildlife with my love of photography. I have been a member of PSA since moving to Florida, USA, in 1990 and have enjoyed all aspects of photography. My first love is still wildlife and I enjoy photographing birds in flight.

About 5 years ago, I took some classes in fine art photography and gained a better understanding of fine art and black and white images. I belong to 2 camera clubs and a fine art group where I find I have learned the most from discussion with fellow photographers.

I have recently retired from practicing dentistry, and am enjoying more opportunities for travel and early morning nature photography.

Originally I'm from WV, but my entire life has been spent in and around Washington, DC. My husband and I now live in the historic district of Staunton, VA. My photo interests vary from flower closeups and nature to rusty things, architecture and abstracts-- eclectic. I joined PSA in 2010 and continue to participate in study groups and assist PSA's Historical Research Committee. I began with a point-and-shoot and graduated to the first mirrorless Lumix which I still use. The Galaxy s9 is my first smartphone, and the seemingly endless options for creativity with it fascinate me. The many opportunities I find through PSA for learning and sharing continue to motivate my interests.




Jose Cartas

Jose Cartas

A native Argentinean, José came with his family to the United States in June 1990 to work for the Interamerican Development Bank. In 2000, he moved to the International Monetary Fund. Both institutions are located in Washington, D.C.

He became a more serious amateur after joining the North Bethesda Camera Club in 1995. He took also several photo courses at the Smithsonian Institution.

Through his work, José has traveled to many countries, and has used this opportunity to photograph cities, landscapes and people. He switched to digital in early 2007, buying a Sony Alpha 100, which allowed him to use the Minolta lenses he already had. Most of his photography is straightforward, using Photoshop to perform only minor adjustments such as levels, curves, brightness/contrast, dodging/burning and, occasionally, some cloning.




Anges van der Logt

Anges van der Logt

My name is Anges van der Logt (my baptist names will be too long to mention ;)..), and I am a Dutch female photographer living in Jakarta, Indonesia. My interest is mainly in Travel, Human Interest and Landscape photography, as you will be able to see on my IG accounts, if interested (@angesvdl and @angesvdl.world).

Photography has been a hobby for me from teener age, as my father was a dedicated hobbyist photographer. As I got more interested, I even had a dark room for some time in the bathroom, where I printed my own black and white images. When the digital cameras came into the market I was sceptical at first, but after seeing the benefits and possibilities these cameras brought with them, I got more and more interested, and self educated myself in post processing (no need for a bathroom anymore). From 2017 or so I started to upload images to photo exhibitions and got a lot of them accepted (to my surprise), so now I am interested in focusing even more on improving my work (hopefully through participating in this digital dialogue group as well) and will be able to get a distinction some time in future.

Thanks for letting me join your group! I hope I can learn a lot here and also give constructing comments and compliments on the other member's photos in this group.

You can see my work on: My Photography Website or Photos from Indonesia (IG) or Photos of the World (IG)

I spent 30 years in Hi Tech manufacturing, responsible for the departments that procured raw materials and scheduled manufacturing. In the late 90's, I hobbied with programming websites and finally decided that, if I were to ever get good at it, I needed to immerse myself. I quit Hi Tech and took a position as a webmaster in Stanford University's School of Engineering, where I became skilled at programming. In 2008, I retired.
My wife and I are equestrians. We're members of our Sheriff's Mounted Search & Rescue Unit as well as trail patrol volunteers for several park districts here in the San Francisco Bay area.
In photography, I enjoy taking photos of the many open space views that my horse takes me to several times a month. I'm also enjoying learning portraiture using off camera flash.
