Enormous, huge, really really big paper negatives

radiant · Apr 1, 2022

I was today at exhbition opening at local gallery where ther was paper negatives done in very crazy size - biggest is about 3×4 meters (118 ” x 157″).

I had a chat with the artist and he is exposing these negatives as pinholes / camera obscura - way. He said some exposures are two days long.

Just crazy.

I put some more photos & writings on my blog at http://blog.vedostuu.fi/

How does he manage to do 3x4 metres, does he place paper of that size into a pinhole camera?

Thanks

Yes.

edit: well actually not one paper but two "strips" of paper.

Most likely sponged on chemicals.

I didn't ask the artist but I assume some sort of DIY "tray" aka flower thingy.

One can develop rolled paper in makeshift, DIY or commercial long-trays. Either manually or mechanized. Basically following the rewinding principle.

There was a guy in Europe who turned a truck into a camera obscura. By this you are with longitudinal projection already at 2.45x2.35m at least, at rectangular projection at an even wider format.

Using a warehouse with a pinhole in a window yields larger formats.
