Hey, thanks!
I get you, the guy at the print-shop I use has asked me several times if my art is artificially generated.
I don’t know what you expect as evidence, but I’ll try.

This is a picture from my last exhibition, and the box there is the scanner-camera.
The fabric is 15 meters by 145cm, I have friends holding it stretched out of frame at both sides.

This is another shot from the same shoot. I think it’s very dynamic, but I like the ‘sunbeam’ from the original post better.

And this is a still from a video I took of my friend playing around With the fabric in the wind before she jumped down from the boulder I made her stand on in order to get the original shot.
I hope that covers it. The wavy pattern is due to the linear sampling of the scanner, and the play of motion over time.
