With volvox film you get bright green dots in different shapes and sizes all over your photographs. The dots are more visible in darker parts of the image and can give the picture a slight 3D effect. Volvox makes your night shots look like they were taken in a field of glow-worms, gives your party pictures that certain edge they normally lack, and even makes shots of a family dinner suddenly seem extravagant.
