Experimental Alchemy: Interventions in Films with Haluro de Clara
"Film soup" is a technique that consists of immersing the roll (before or after being exposed) in any substance of interest. This causes "stains" on the film that will be "printed" with the images after developing. You can use both concentrated and light mixtures, depending on the intensity of the substance you can leave it submerged for more or less time (from 1 hour to days). Lighter or less ingredient mixtures can be left for weeks - e.g., water kefir + Lomography 100, 1 week. For more concentrated mixtures or those with many ingredients, it's advisable to leave the rolls for less time, 1 hour to 1-3 days maximum. In any case, it's useful to observe the bit of negative coming out of the chassis to see the "level" of effects and decide whether to leave it longer or take it out to dry/develop.
