At this point in my exploration of Dreamstime, I've hit a wall: I've combed through my existing photos for shots that might have commercial value, and submitted most of those.
I have no travel on the immediate horizon, and so, for now, my subjects are limited to my immediate area.
For better or worse, I live in Washington, DC. The better: There are many, many iconic buildings here, from the Capitol to the White House to all the Smithsonians. The worse: These might just be the most photographed buildings in the country, with everyone from tourists with disposable cameras to the most accomplished pros capturing images of all the settings, in all seasons.
So, how do you get started? How do you make that break between re-purposing existing photos to creating photos for stock? I've got a bit of time, and decent equipment--it's the familiarity of my surroundings, not only to me, but to the rest of the world--that is the issue.
BTW, attached is a shot of the interior of the Library of Congress that I took a couple weeks ago. This wasn't a deliberate photo-expedition, but the building is so amazing that I couldn't resist taking several shots.
