Blue

We're obsessed with cyanotype – that 19th-century photographic process that turns sunlight into art. Danish summers might be short, but we make the most of every UV ray. This isn't your grandmother's nature printing.

Cyanotype lab in Vasterbro

BluePrint opened in 2019 in a former darkroom space on Istedgade. We focus exclusively on cyanotype because we think it's criminally underrated. The process is analog, unpredictable, and completely addictive.

Who We Are

Kai
Handles everything digital while staying firmly analog in the darkroom. They're usually covered in chemistry stains and loving it.

Nils
The business brain who somehow convinced a bank to fund our cyanotype dreams. He also makes the best coffee in Vesterbro.

Maya
Our curator and resident plant obsessive. She sources specimens from Copenhagen's botanical gardens and beyond.

Lars
Former chemistry teacher turned gallery director. He knows why your prints are coming out patchy and probably has the fix.

Our work

Cyanotype is chemistry meeting light. Iron salts, UV exposure, water wash. Simple ingredients, infinite possibilities. We've been pushing the traditional recipe – experimenting with different papers, exposure times, even LED arrays for winter months.

Process

Every piece reacts differently. Copenhagen's unpredictable weather actually works in our favor – overcast days create softer exposures, bright winter sun burns sharp contrasts. Check our process documentation on Instagram.

Astrid Sonne works with invasive plant species collected from Copenhagen's abandoned lots. Her large-scale cyanotypes capture weeds and urban flora in forensic detail, turning botanical "nuisances" into striking blue monuments.

Freja Bak elevates the most overlooked garden weeds – dandelions, plantain, clover, chickweed. Her cyanotypes turn these common "nuisances" into detailed botanical portraits, revealing the intricate beauty we usually try to eliminate.

Magnus Andersen manipulates traditional cyanotype chemistry to create deep blue gradients. His series focuses on carnivorous plants capturing their predatory mechanisms in haunting detail.

We're tucked between a vinyl shop and a natural wine bar on Istedgade. Entry is free, but we sell prints and artist books if you want to take something home.
