Previous tests have shown, that a medium that had synthetic ultramarine blue pigment in it, inhibited the growth of physarum. As a workaround, the timelapse-medium had a thick layer of blue medium and on top on that approximately a millimeter of normal, clear medium. With that, a test timelapse was shot overnight (about 10 hours of time). The camera used, was a blackmagic pocket cinema camera 4k, which had the unique advantage of the option to be cable-powered without any accessories. The timelapse was shot in BRAW 12:1 and 3840 by 2160 px and the resulting video was 3 minutes and 16 seconds long. | Previous tests have shown, that a medium that had synthetic ultramarine blue pigment in it, inhibited the growth of physarum.

Because oat flakes in the shot would give away the true scale of the image, a bedding of E. coli bacteria was grown and prepared on the plate. The shot was lit by a continuously running LED-Panel with a power of 15w. | Because oat flakes in the shot would give away the true scale of the image, a bedding of E. coli bacteria was grown and prepared on the plate.

Sadly, the specimen of physarum was not very strong and grew only very little during the interval. | Sadly, the specimen of physarum was not very strong and grew only very little during the interval and what grew hat only a very faint yellow tint. | ||

To see if it would be usable, a test shot was filmed, 3D Tracked, the footage composited in and graded. | To see if it would be usable, a test shot was filmed, 3D Tracked, the footage composited in and graded. The oatflake was masked out to make the slime mold appear larger in size. | ||
In order to hide the bad resolution and make the Physarum more alien-like, a vector blur was applied. | In order to hide the bad resolution and make the Physarum more alien-like, a vector blur was applied. | ||
