How to photograph "black holes" and "wormholes"?

Another photo session painted with light resulted in the creation of "spacetime tunnels" :-). To create them, I used a light circle. Later, all that was left was to expose the frame while simultaneously moving this circle and moving closer or further away from the camera. If you want to know the details of how these photos were created, I invite you to visit the blog page https://fotografiadlaciekawych.pl/index.php/2024/04/04/malowanie-tuneli-czasoprzestrzennych/
