I happened to be in Oregon, in Coss Bay area. I went to the state parks nearby. The photo above was taken in Shore Acres State Park. It’s a 8 stitch panorama at 5 seconds each frame. I used 5 seconds because I wanted to have some wave action details. I used a 3-stop ND filter to have 5 seconds but I had to use F/22. I could have used a 10-stop ND filter here without sacrificing my aperture but my 10-stop ND fell in the sand, LOL.
