What is Safelight?

Safelight is a lamp that produces light in the areas of the spectrum that will not affect photo -C and photographic paper. Safelights are used in dark chambers to ensure light for work without endangering materials processed in the Dark Chamber. While many people can connect red light with Safelights, Safelights actually comes in a number of colors and different types of photographic materials come up with different Safelight recommendations. It is important to follow these recommendations to prevent fogging or otherwise threatening these materials.

Safelights can work in one of two ways. Some consist of living with a filter holder. Others consist of a bulb, which was covered with a material that will act as a filter. Some manufacturers of photographic stocks, such as Kodak, specifically recommend working with filtered secure lights because the filter blocks more potentially dangerous light. Both types are easily accessible from photography C, withField with accessories such as swivel handles that allow people to turn Safelight for better lighting a particular area in the darkroom. One of the advantages for filtered Safelight is that it is easy to change the filter for specialized applications. For example, if someone regularly works with a red Safelight and a certain brand of photographic paper recommends instead of Amber, an amber filter can be simply inserted into the filter holder.

It is not safe to work under safety indefinitely; Long -term exposure can damage photographic materials, especially because sensitivity to light does not suddenly stop in one spectrum area, which means that safety light eventually leads to fogging and other problems. Also, some types of photographic material cannot be used with any type of light, which requires complete darkness. Photographers and other people who work SH photographic materials such as lithographic yewDisciplinary and X -ray techniques must also be aware that Safelight filters disappear over time, which means that they can start dangerous light. Filter companies usually contain recommendations on how often the filter should change based on the level of use to ensure that the filter is effective.

Amber and Red are two popular colors for Safelights. Recommendations on packaging for photographic materials usually include color recommendations and power recommendations to ensure that people use bulbs of suitable brightness. It is also a good idea to regularly change Safelight bulbs, as bulbs can grow over time due to the deposition of materials on the inside of the bulb.
