Cyanotype is the most magical entry into alternative photography: you brush a light-sensitive solution onto paper or fabric, lay objects or a negative on top, expose it in sunlight, and rinse to reveal a deep Prussian-blue print.

It's nearly foolproof, cheap, and the reveal in the water is genuinely thrilling every time.

The honest reality is that it's blue (it's the whole charm, but it is one colour), results depend on the sun, and the chemistry, while gentle, still wants sensible handling and gloves.
