Starr's Mill dates back to 1907, when it was rebuilt by William T. Glower because the previous mill was destroyed by fire. This Georgia mill site went on to power a cotton gin and supply electrical power to the nearby town of Senoia.

Starr's Mill is located here.

To shoot Starr's Mill, I'd recommend the following:

Get there first thing in the morning. Once the afternoon arrives, the sun doesn't reflect as well off the main red barn. Late in the afternoon and/or early evening might also be a good time to shoot.
Bring a tripod, as well as a neutral density filter. You'll want this in order to blur out the water background and get some really creative shots.
I'd recommend a wide angle lens such as a 16mm.

For the shoot, I used the following:

Fulifilm X-T2
Lens: Fujinon 16mm
Filter: 10-stop neutral density

Be sure to not only shoot from the parking lot area, but also walk around the front of the park so that you can get the entire waterfall with the barn behind it. In order to do this, you may need to walk along the highway because there's no easy way to cross the river. It's about a 3-5 min walk, but be careful, as there's no sidewalk and you are basically walking along the side of the highway.

You'll probably end up spending about 30-45 minutes there. All in all, a nice place to jump off and get some really great landscape shots.
