A moment of awkward self-promotion to mention that I sell prints of my photography. You can buy from www.markrcourtney.com or contact me there if something catches your eye.

You can also visit photo.mrcourtney.com to see my in-person events and find the places to follow my #photography.
A promotional image with the text "Mark R. Courtney Photography" and website address "markrcourtney.com" surrounded by five sample photographs: (1) a bank of fog and moored sailboats on the water, (2) an orange California poppy covered in water drops, (3) coastal water gently washing around small colorful rocks, (4) the flowering stem of a purple wild lupine, and (5) a brown bird splashing in golden-lit water.

White-tailed deer in a tall field
#WildlifeWednesday #Wildlife #WildlifePhotography #Photography
Photograph of a deer in a brushy field of seasonally dry plants that reach to its shoulders. Only its head and back are visible, and some of the plant seed heads rise to the level of of the deer’s alert ears which are angled slightly back though its eyes seem to be scanning the brush ahead.

Feather left behind
#Nature #NaturePhotography #Photography
Photograph of a wide feather caught on a bare plant stem. The outer edge of the feather fans out in a subtle black, and it shifts to white and fluffy where it once attached to a bird but where it now clings to a twig.

Pavilion structure
#Architecture #Photography
Photograph looking along a narrow, curved support made of layered wood that leads up to the wooden slat ceiling of a large, open pavilion. The support catches the low morning light making the near curve glow against the dark ceiling and highlighting a decorative, angled gap near the top. The entire photograph is just these woods of various shades running at various angles.

Along the Narragansett Bay coast this morning

Photograph of a rust-red leaf floating above rocks and shells just under the water's surface near shore. Photograph of a large, wet rock near shore. The dark rock is solid but covered in carved out pockmarks and has a single orange-brown leaf sitting atop it as the only splash of color. Photograph of dark-shelled sea snails on a flat slope of rock leading down to the water where the waves occasionally splash over them.

Morning frost and frozen water drops
#Frost #Nature #NaturePhotography #Photography
Closeup photograph of morning frost formed along the lengthy, parallel ribs of a gladiolus leaf with some frozen water drops scattered about. Aside from the jaunty angle, it has the look of music notes written on a lined staff.

Waves coming off the basalt columns at Reynisfjara black sand beach. It's amazing that the camera technology is so good now that this was handheld at 1/8th second - the columns are sharp but I was able to capture the movement of the water too.

#CanonR6II #Iceland #Geology
A large cliff of different-sized black basalt columns with some water trailing off the lower ones at the bottom and a bit off the top right ones. The water is quite smooth as the exposure length was slowed down.
