A "safelight" is a type of lighting used in photography darkrooms to allow photographers to see while working with light-sensitive materials. It emits a specific wavelength of light that does not affect the photographic paper or film, preventing unwanted exposure. Common colors for safelights include red and amber, as these wavelengths are less likely to cause damage to most black-and-white photographic materials. Safelights are essential for developing photographs, as they help maintain the integrity of the images being processed. They are often used alongside other equipment, such as developing tanks and enlargers, to create high-quality prints without compromising the sensitive materials involved in the process.
