Explorations Photographiques
This site documents a collection of technical essays dedicated to alternative photographic printing processes and creative chemistry.
This project, which initially began as a simple series of experiments on cyanotype toning, has gradually evolved into a broader personal research endeavour. While a significant part of this repertoire is devoted to the infinite nuances of cyanotype—from simple toning to more complex techniques—it also extends to other historical processes, as well as original methods resulting from my own research and rediscoveries.
By design, this space is conceived as a raw and refined database. You will find no comments section or contact form, in order to prioritise the clarity of technical information and immersion in the photographic material.
Lists of processes
Standard Experimentation Protocol
To ensure the consistency of this test database, a standard protocol is applied to all data sheets, unless otherwise specified:
- Support: Standard watercolour paper (common quality), selected for its stability during large-scale test series.
- Insolation: Exposure via UV LED array (wavelength of 365 nm), providing a constant and reproducible light source.
- Processing: Rinsing with softened and filtered water (pH 7). Note: the water used is not demineralised.
- Environment: Preparation and handling carried out under semi-inactic lighting (yellow LEDs).
Safety and Responsibility
The use of the processes presented in this directory involves handling chemical substances that are not harmless. Alternative photographic chemistry requires absolute rigour and strict adherence to safety protocols.
Prevention and Personal Protective Equipment (PPE)
It is essential to accurately research the toxicity of each substance before use. All handling must be carried out in a dedicated, properly ventilated space. Wearing appropriate equipment is mandatory:Gloves (Nitrile), sealed goggles, and lab coat.
Respect for the Environment
Discharging chemicals into domestic wastewater is strictly prohibited. Contaminated residues and rinse water must be disposed of at an approved hazardous waste treatment facility.
Specific Risks Associated with Listed Substances:
- Strong Acids and Bases: Risk of severe chemical burns and violent exothermic reactions.
- Cyanide Complexes: Risk of acute toxicity. Never mix with strong acids or heat (release of deadly gases).
- Heavy Metals (Lead, Mercury, Chromium): Highly toxic, bioaccumulative substances, often classified as CMR (Carcinogenic, Mutagenic, Reprotoxic).
