A notebook to track your experiments. Lumen-based processes are wonderful to work with – playful, experimental, and full of unexpected beauty from both a carefully planned print to "happy accidents". Changes in light, moisture, paper, chemistry, and exposure can produce remarkable results, making every print unique. But with so many variables, it is very easy to forget what you did once time has passed. And if you cannot remember the steps, how do you recreate a result? This practical notebook is designed to help you record and refine your experiments. With a customised layout to document up to 50 lumen, cyanolumen, chemilumen, and phytogram prints, it helps you track materials, conditions, timings, techniques, and reflect on the final outcome. A valuable companion for repeatable results, learning from your own mistakes, and developing your own creative process.
