Here are some local Calls for Art in October:

• Waterford Fair has a juried photography show that gives you a good chance to sell your work The fair is October 6,7 and 8. The deadline for entries is Sept. 27. https://waterfordfairva.org/participate/photography-exhibit/
• A Solo show at 1st Stage is a big one! They have a lobby and long corridor so you probably need to have at least 18 framed pictures depending of course on their size. Contact the curator, Deborah Conn at deborahconn@verizon.net. This venue does not predominantly show nature photos, but anything “artsy” is a possibility. Look at their past shows to get a feel for what they might be looking for. http://www.1ststagetysons.org/plays-events/ and scroll all the way down for the Gallery Archives. They favor emerging actors and emerging artists—the name 1st Stage connotes first time participants. It was my first show—season 6 in their archive.  Look at their past shows to get a feel for what they might be looking for.
• Northern Virginia Review’s annual call for art is still open until Oct. 15 and they give a cash prize. https://blogs.nvcc.edu/tnvr/submissions/ .  Again, look at their past issues to get a feel for what they might be looking for.
