Brassing refers to a common occurrence in the photography world when a photographic print or image exhibits a color shift towards a yellow or brown hue, resembling the appearance of brass. The term is commonly used to describe the undesired discoloration that may affect black and white or color photographs, film, or any other type of printed image.
This phenomenon is typically caused by the degradation or chemical changes in the materials used in the image-making process, primarily due to exposure to environmental factors, such as light, humidity, or air pollutants. It can also be a consequence of poor storage conditions, improper handling, or the use of low-quality materials.
The effects of brassing can vary depending on the severity and duration of the exposure. In minor cases, it may result in a slight color shift, while in more severe instances, the entire image may become heavily discolored, compromising its original quality and aesthetic appeal.
To prevent or minimize brassing, photographers and collectors often take precautionary measures, including the use of archival-quality materials, proper framing techniques, and controlled storage conditions. Additionally, digital technology has provided a solution to the problem by allowing for the digital restoration of brassed images, reproducing their original colors and enhancing their overall visual quality.
