How to Create a Portable Darkroom for at Least Ten People
Introduction
Creating a portable darkroom that can accommodate a group of at least ten people requires careful planning and consideration. Whether you are interested in black and white (BW) film processing and printing, or color film and slides, this guide will help you decide on the best options for your needs.
Considerations
When designing a portable darkroom, several factors should be considered:
Space for 10 people: The darkroom should provide enough space for ten people to work comfortably and efficiently. Light tight conditions: The darkroom must be light tight to ensure that light-sensitive materials can be processed correctly. Non-light tight area for film processing: An optional non-light tight area can be used for film processing to separate it from the print-making area. Environmentally comfortable for users: The working environment should be comfortable, with proper temperature and humidity control. Ventilation: Adequate ventilation is necessary to manage chemical vapors and ensure a safe working environment. Running water: A steady supply of water is essential for rinsing and washing film and prints. Storage of used chemicals: A place to store used chemicals must be provided to maintain safety and compliance. Electrical power: Reliable electrical power is necessary for lights, cooling systems, and other equipment.Practical Solution: Converting a Large Recreational Vehicle (RV)
The most practical solution for a portable darkroom is to convert a large recreational vehicle (RV) that is approximately 10 meters (33 feet) long. Here’s why:
Space for ten people: An RV of this size provides ample space for ten people to work comfortably. Light-tight conditions: An RV can be made light tight by covering or removing the windows and installing professional blackout curtains or shades. Easily subdivided: The RV can be easily subdivided into dark and light areas, with a clear partition. Environmental control: Most RVs come equipped with at least two air conditioners and heaters, making it possible to maintain a comfortable temperature for the users. Ventilation: Additional powered vents can be added to manage chemical vapors and provide fresh air. Running water: RVs are built with a potable water tank and pump system, ensuring a steady supply of water for processing and rinsing. Storage of used chemicals: RVs are built with tanks for toilet waste and gray water, which can be used to store used chemicals safely and comply with environmental regulations. Large internal space: The large interior space of the RV allows for proper workflow and equipment storage.Alternative Solutions
If converting an RV is not feasible, consider the following alternatives:
1. Using a Clearspan Marquee
A small clearspan marquee fitted with opaque black PVC roof and walls can serve as a portable darkroom. Adding a black serge liner further enhances light tightness and allows for the construction of an airlock entrance. Depending on the location and duration of use, additional ventilation or air conditioning may be required.
2. Converting a Caravan or Container
Caravans and containers can also be converted into portable darkrooms. These options offer sturdy, weather-resistant structures that can be equipped with necessary amenities and lighting systems.
3. Renting a Light-Proof Tent
For a quick and easy solution, consider renting a light-proof tent from a local rental company. Specify your requirements and ensure the tent meets the necessary light-tight standards to accommodate ten people.
Conclusion
Creating a portable darkroom for a group of at least ten people involves careful planning and selection of the right solution. Whether you choose to convert an RV, use a clearspan marquee, or rent a light-proof tent, the key is to ensure adequate space, light tight conditions, and a comfortable working environment. By following these guidelines, you can create a portable darkroom that meets your needs and provides a safe and productive working space for your projects.
