These were photographed at ‘Soldiers Ground’ a few days after Memorial Day.
There was just enough breeze for flags to slow move giving different looks as they unfurled. Basically shoot many images and decide which to keep later.
Because this is on land owned by a historical trust there are no restrictions on what flags can be flown. During the US Civil War there were a large number of different flags. Even the brief country of South Carolina. This makes for interesting colorful images.

Photographed using OM-1 mk2, OM 12-100 f4, Lightroom, DxO Filmpack, DxO Color Efex.
