ok, here I have a #mystery, the #FujichromeR25 #Single8 #film was stored outside for years, wet. When developed to bw it has these triangle patterns on emulsion. some kind of crystallization, but what and how?

Very interesting, those patterns look almost fractal, like a SierpiƄski gasket. I am very curious what process caused this, would be very nice if it could be repeated in a more controlled manner.

@mstenta yeah it is that, but some analog process to it
