spent 2 months in Project X, testing different photographic emulsions under extreme radiation—from hospital X-rays—to determine which would hold up best
What you’re looking at is an amalgamation of muons, formed millions of light year away from black holes, and UVC radiation usually filtered out by the ozone layer, but now etched onto this canvas and potentially electrical discharge due to the static build up between the dark bad and the film
UVC? So the film did get direct exposure? Because UVC should usualy not penetrate thru film can material.
It does just look like a light leak to me.
