I found an unused roll of slide film which had its expiration date set in 2001. I took some pictures with a Yashica Electro 35, then took the film to the local Lomography shop so they cross-processed it as regular C41 negative.

This is what happened.

Details of the staircase outside my studio, shot with my Spotmatic. I was once told this is Porto's oldest concrete building. Which is nice, I guess.
