Cyanotypes are a unique and captivating form of photographic printing that has been around since the mid-19th century. The process, which involves using sunlight to create blue and white prints from objects or negatives, has been a favorite among artists and photographers for its distinctive aesthetic and tactile qualities. However, one question that often arises when considering cyanotypes is: do they fade? In this article, we’ll delve into the world of cyanotypes, exploring their history, the science behind the process, and the factors that affect their durability.
A Brief History of Cyanotypes
Cyanotypes were invented in 1842 by Sir John Herschel, an English astronomer and photographer. Herschel discovered that by using a solution of potassium ferricyanide and ferric ammonium citrate, he could create blue and white prints from objects or negatives. The process was initially used for botanical and scientific illustrations, but it soon gained popularity among artists and photographers for its unique aesthetic qualities.
The Cyanotype Process
The cyanotype process involves several steps:
- Preparing the paper: The paper is coated with a solution of potassium ferricyanide and ferric ammonium citrate.
- Creating the negative: A negative image is created, either by drawing or printing onto a transparent surface.
- Exposing the paper: The paper is exposed to sunlight, with the negative placed on top.
- Developing the print: The paper is washed and fixed, revealing the blue and white image.
The Science Behind Cyanotype Fading
Cyanotypes are prone to fading due to the nature of the chemicals used in the process. The potassium ferricyanide and ferric ammonium citrate solution is sensitive to light, and when exposed to sunlight or artificial light, it can break down over time. This breakdown causes the blue pigment to fade, resulting in a loss of image density and contrast.
Factors Affecting Cyanotype Fading
Several factors can contribute to the fading of cyanotypes, including:
- Light exposure: Cyanotypes are most susceptible to fading when exposed to direct sunlight or high levels of artificial light.
- Humidity: High humidity can cause the paper to degrade, leading to a loss of image quality.
- Temperature: Extreme temperatures can cause the chemicals to break down, resulting in fading.
- Storage conditions: Improper storage, such as exposure to moisture or light, can contribute to fading.
- Aging: Cyanotypes, like all photographic prints, will naturally degrade over time due to the aging process.
Preserving Cyanotypes
While cyanotypes are prone to fading, there are steps that can be taken to preserve them. Here are some tips for preserving cyanotypes:
- Store in a cool, dry place: Avoid exposing cyanotypes to direct sunlight or high humidity.
- Use acid-free materials: Store cyanotypes in acid-free paper, boxes, and mats to prevent degradation.
- Avoid touching the surface: Oils from skin can damage the surface of the print, causing fading or discoloration.
- Use UV-filtering glass or acrylic: When framing cyanotypes, use UV-filtering glass or acrylic to reduce exposure to ultraviolet light.
- Make a digital copy: Consider making a digital copy of the cyanotype to preserve the image for future generations.
Conservation and Restoration
In some cases, cyanotypes may require conservation or restoration to preserve their integrity. This can involve:
- Cleaning the surface: Gently cleaning the surface of the print to remove dirt or debris.
- Repairing tears or damage: Repairing tears or damage to the paper to prevent further degradation.
- Re-framing or re-mounting: Re-framing or re-mounting the print to improve its stability and prevent further damage.
Conclusion

What is a cyanotype, and how does it work?
A cyanotype is a unique photographic process that uses sunlight to create blue and white prints from objects or negatives. The process involves coating a surface, typically paper or fabric, with a light-sensitive solution containing potassium ferricyanide and ferric ammonium citrate. When exposed to sunlight, the solution reacts to the light and creates a blue and white image.
The resulting print is a negative image, meaning that the areas exposed to the most sunlight will appear white, while the areas that received less sunlight will appear blue. The cyanotype process is often used to create artistic prints, as it produces a distinctive and dreamlike quality. The process is also relatively simple and accessible, making it a popular choice for artists and photographers.
Do cyanotypes fade over time?
Yes, cyanotypes can fade over time due to exposure to light, moisture, and other environmental factors. The blue pigment in cyanotypes is sensitive to ultraviolet (UV) light, which can cause it to break down and lose its intensity. This means that cyanotypes that are exposed to direct sunlight or fluorescent lighting for extended periods may fade more quickly.
However, there are steps that can be taken to slow down the fading process. For example, cyanotypes can be displayed in low-light conditions, or they can be treated with UV-filtering glass or acrylic. Additionally, some artists and conservators use specialized techniques, such as toning or coating, to help stabilize the pigment and prevent fading.
How can I prevent my cyanotype from fading?
To prevent your cyanotype from fading, it’s essential to display it in a way that minimizes its exposure to light. This can include displaying it in a dimly lit room, using UV-filtering glass or acrylic, or storing it in a dark place when not on display. You can also consider using a frame with a UV-filtering glaze or acrylic to help protect the print.
In addition to controlling the lighting, it’s also important to handle your cyanotype with care. Avoid touching the surface of the print, as oils from your skin can damage the pigment. You should also avoid exposing your cyanotype to moisture, as this can cause the pigment to break down. By taking these precautions, you can help ensure that your cyanotype remains vibrant and intact for years to come.
Can I display my cyanotype in direct sunlight?
It’s generally not recommended to display a cyanotype in direct sunlight, as this can cause the pigment to fade quickly. Direct sunlight contains high levels of UV radiation, which can break down the blue pigment in cyanotypes and cause it to lose its intensity. If you must display your cyanotype in a sunny location, consider using UV-filtering glass or acrylic to help protect the print.
However, even with UV filtering, it’s still possible for a cyanotype to fade over time if it’s exposed to direct sunlight for extended periods. If you want to display your cyanotype in a sunny location, consider rotating it with other prints or storing it in a dark place for part of the year. This can help minimize its exposure to light and prevent fading.
How long does a cyanotype typically last?
The lifespan of a cyanotype can vary depending on how it’s displayed and cared for. If a cyanotype is displayed in direct sunlight without any protection, it may only last for a few years before it starts to fade significantly. However, if it’s displayed in low-light conditions and handled with care, a cyanotype can last for decades.
In general, a well-cared-for cyanotype can last for 20 to 50 years or more without significant fading. However, this can vary depending on the specific conditions in which the print is displayed. Factors such as temperature, humidity, and exposure to pollutants can all affect the lifespan of a cyanotype.
Can I restore a faded cyanotype?
In some cases, it may be possible to restore a faded cyanotype, but this can be a complex and delicate process. The first step is to assess the condition of the print and determine the cause of the fading. If the fading is due to exposure to light, it may be possible to restore the print by re-exposing it to sunlight or using a specialized toning solution.
However, if the fading is due to damage to the pigment or the paper, restoration may be more difficult or impossible. In some cases, conservators may be able to use specialized techniques, such as consolidation or repair, to stabilize the print and prevent further damage. However, these techniques should only be attempted by a qualified conservator, as they can be risky and may damage the print further.
Are there any alternatives to cyanotypes that are more durable?
Yes, there are several alternatives to cyanotypes that are more durable and less prone to fading. One option is to use a different photographic process, such as gelatin silver printing or inkjet printing, which can produce more stable and long-lasting prints. Another option is to use a digital printing process, such as giclée printing, which can produce high-quality prints that are resistant to fading.
Additionally, some artists and photographers are experimenting with new techniques and materials that can help to stabilize and preserve cyanotypes. For example, some artists are using specialized coatings or varnishes to protect the pigment and prevent fading. Others are experimenting with digital cyanotypes, which can be printed using inkjet printers and are more resistant to fading than traditional cyanotypes.
