How to get light swirl on film ?

[shadowbecomeswhite]

This artist uses a Holga120S with using a remodeled board. I don't understand what a remodeled board is. I think she uses Fujichrome 120 format color film or the Velvia color film.

I want to learn how to do this with 35mm and 120 film. Does anyone know ?

She replaced the lens with a pin hole. You can get a similar effect with a pinhole lens or camera. You could probably even make one yourself using a piece of black construction paper.
