When I first saw it, I didn't think it was a double exposure. Then I looked closer and thought the netting seemed to be passing through the tower, and why wouldn't it be over the top of the tower, so I decided it was a double. But I was right the first time.I took several shots of this from different angles, picked my favourite on snapseed, saved the original B&W version then done a silhouette version of the same image and blended the two to create the contrast I wanted, but all from one original shot of the tower and netting, if that helps explain how I ended up with this final image.
This is the one and only photo I used.
It's not a superimposed photo of a jellyfish
