Anthtoype by Dennis Humprey

Amount: 1 tbsp powder in 165 mL water & 10 mL vodka
Extracted using: n/a – used purchased powder
Thinner: Distilled water + vodka
Layers: 2
Used to create image: Laser-printed OHP positive (x2) of a bursting seed pod

Challenges or observations: This was my first anthotype ever. I prepared too much emulsion, though; also, it was lumpy and smelly. Application was streaky with a brush. The print could probably have been exposed for another day or so for better contrast.

The Spirulina powder was a rich, velvety blue-green. 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.
