At present, I’ve been using Serrated Wrack seaweed, sourced from both Sands of Sound in Lerwick and Minn Beach in Burra. I will also be testing Egg Wrack, Bladder Wrack and Kelp. Each time, I’ve only taken small amounts to ensure minimal impact on the local ecosystem.

Before collecting, I checked carefully to ensure there were no small sea creatures living within the harvested seaweed, such as tiny sea snails. The few that I did find, I gently returned to the seaweed I hadn’t touched.

​

I am beginning my tests using two of the most affordable film brands, Fomapan and Kentmere. Part of my ethos in photography is to show people the most accessible, budget-friendly, and eco-conscious ways to engage with analogue photography, helping to ensure it does not become a thing of the past. I hope for analogue photography to continue long into the future, remaining open and achievable for all who wish to learn, experiment, and create.

​

For both Fomapan and Kentmere films, I will be working to determine development times for 100, 200, and 400 ISO, as these are the most commonly used film speeds. Establishing clear, reliable times for these will make it easier for others to confidently use eco-friendly seaweed developers in their own analogue practice.

​

Over time, I hope to expand this research by testing additional film brands such as Ilford and Kodak, as well as exploring other ISO speeds. This will allow me to build a broader, accessible knowledge base for those looking to embrace sustainable analogue photography without sacrificing quality or consistency in their results.
