The original photo was shot in color on an iPhone 11 Pro. I cropped it and converted it to black and white using the Photos app on the iPhone. I then imported the the image into Photoshop where I used Topaz Labs Black & White Effects filter to create the cyanotype. Below are the original and converted photos.

Original photo.
The German zeppelin Hindenburg floats past the Empire State Building over Manhattan, on August 8, 1936, en route to Lakehurst, New Jersey, from Germany. The fate of the Hindenburg (less than a year later) is depicted in the left photo below. For more interesting photos, visit Rare Historical Photos.
When trying to catch the motion of moving water, use a slow shutter speed. In this case, ⅓ of a second. You should preferably use a tripod, although this photo was taken hand held. You can tell because the rocks show a bit of motion blur, in other words they are not sharp. Even with the blur, the image takes on a painterly effect, making it work.
When shot with a faster shutter speed (1/60 of a second), the motion of the water is not captured in the resultant image. It appears as a single frame in a motion picture.
Notice the focus is on the reflection, so the foreground goes out of focus.
This photo (left) of the rock bowl is interesting, and you do get some of the depth-of-field effect, but the closer view (above) is more dramatic. Hence, a better photo. Don't be afraid to move closer.
I once had a photo professor tell me, "If your photos aren't good enough, then you aren't close enough."
Wise words, indeed.
