Alter-Ego, showcases portraits of sub-cultures like Cosplay, LARP, Steampunk, and Lolita Fashion. The series goes beyond the world of fantasy and explores the sense of safety and freedom these sub-cultures offer to "be who you want to be." At the core of these sub-cultures is the expression of make-believe and play, while also addressing the question of belonging, identity, and acceptance. Through his lens, Ulrich not only captures the costumes but also presents the invitation to the worlds in which these characters wish to live and the people they identify as.

Despite its appearance, the series is not involving any digital process or even computer-generated (AI). Ulrich’s work is created through a traditional approach to black and white photography. All his works are captured on film using medium and large format cameras. Afterward, the film is developed in complete darkness with chemicals, and the negative is enlarged onto silver gelatine paper, which is then processed and developed in the darkroom. The oil colours are applied by hand through a multi-hour process of colouring and shading to achieve the final result. This hands-on, analogue process ensures that each print is unique.
