Whats immediately striking about slime molds is their unique look. The fine details and the seemingly chaotic structure are simply enchanting. So the question is: Is it possible to transform images of slime mold into usable assets for VFX works? And to be precise: The goal is not to recreate, but to use actual footage. So what needs to be done is to make keyed versions of timelapse footage of physarum growing, that can then be reapplied in changed perspective to other surfaces in vfx software such as Adobe After Effects. | Whats immediately striking about slime molds is their unique look.

Normaly, keying is done by shooting objects against a green background. However, since Physarum tends to be a green-yellow color, blue seems to be a better alternative. It offers both greater color- and luminance-contrast. | Normaly, keying is done by shooting objects against a green background.

Secondly, in order to see the finest details it is necessary to shoot as high resolution as possible. To maximize any cameras resolution, it is best to let Physarum grow on square plates (best in 4:3 ratio) to use the whole sensor. | Secondly, in order to see the finest details it is necessary to shoot as high resolution as possible.
