Anthtoype by Dennis Humprey
Algae powder used for anthtoypesAmount: 3 tbsp powder/ 500 mL water + 30 mL vodka
Extracted using: n/a
Thinner: Distilled water + Vodka
Layers: 2
Used to create image: Laser printed OHP positive of a bursting seed pod x2

Challenges or observations:
Spirulina is a rich blue-green powder. For me, the colour green is linked to growth and renewal; light blue evokes peacefulness. The bursting seed pod also gives us hope for renewed life and peace.
I prepared too much emulsion; also, it was lumpy and smelly. The anthotype print could probably have been exposed for another day or so.
