This is an image of two friends of mine djing an underground techno party called Technocafé. I added a second image for a little bit of perspective on the overall scene.
Both images were taken on a Bronica ETRsi medium format camera using Portra 160 NC film, expired since 2009. The lens in use is a 75mm Zenzanon EII f/2.8.
The images were scanned from negatives using a digital camera, with synchronised flash as a backlight and then converted to positive in Adobe Lightroom.
