The platinum–palladium process, introduced in the early 19th century, remains one of the most enduring and respected printing methods in photography. Each print involves creating a new negative at the chosen size, hand-coating high-quality watercolour paper with platinum, palladium, and iron salts, and exposing it under UV light. The paper is then developed, clarified, and washed. Because the metals are exceptionally stable, these prints have an archival lifespan that spans centuries.

Carbon prints are produced using Kohlepigment Piezography K6, a monochromatic system known for depth, detail, and tonal subtlety. Pure carbon pigments are printed on 100% cotton rag, acid-free papers, giving these prints a rich surface quality and long-lasting stability. It is considered one of the highest standards in black-and-white printing today.

Giclée prints use archival pigment inks and museum-grade papers to achieve refined tonal transitions and vivid colour expression. Printed on 100% cotton rag, acid-free papers with an ultra-smooth surface, they offer exceptional clarity and subtle detail.

Each edition print is individually signed and numbered and comes with a Certificate of Authenticity. The certificate records the title, edition number, and key details of the artwork, and is signed and dated. Keeping the certificate with your archival documents helps maintain clear provenance.

Prints are offered unframed to allow full flexibility in how they are presented. Guidance on conservation framing, mounting, and long-term care is available upon request. For handling, gloves are recommended, and framing should be entrusted to professionals familiar with archival standards.
