As we’ve discussed above, safelights come in many different flavors. Bear in mind that the higher you go, the less visible the light will be. Another traditional photographic safelight is the bare bulb safelight like the Delta 1 pictured above. Many photosensitive materials used in technical and industrial applications, such as photoresist, are sensitive only to blue, violet, and ultraviolet light and may be handled under a brighter yellow safelight. & Home App. We also use third-party cookies that help us analyze and understand how you use this website. Depending on the amount of darkroom printing you do, this might make an LED the only safelight you ever buy.

Create a B&H Account, America's Best Customer Service List-Newsweek, Prices, specifications, and images are subject to change without notice. To do this correctly, you need to find out the spectral sensitivity of the photosensitive product you want to use. This is the most important characteristic.

On the other hand, orthochromatic film is only sensitive to blue and green light and can be safely used under a red safelight. The email address you entered was an invalid email. You can always dim down the light with a filter, a dimmer switch or simply by bouncing it off a wall or ceiling. Not responsible for typographical or illustrative errors. For example, Kodak Panalure panchromatic paper is tolerant of limited exposure to light filtered through a Kodak 13 Safelight Filter. An amber safelight (Kodak OC for example) sits lower at about 590 nm and has (somewhat limited) use in color darkroom processes. The main advantage of this design is the flexibility it provides. If you’re gearing up for your first darkroom, check out our other guides like the Darkroom Printing Equipment Essentials and the Darkroom Timers Buying Guide. If you get a random red-tinted lightbulb or LED emitter, you may or may not be able to successfully use it as a safelight. Check out the rest of our thorough darkroom guides like Darkroom Is Possible: Blackout and Focus Finder for more tips and ideas. [citation needed], The word "safe" in "safelight" is relative, as in most cases, a sensitised material eventually will be affected by its safelight if exposed to it for an extended length of time. Here’s what Ilford has in their Multigrade RC Papers technical information sheet: ILFORD MULTIGRADE papers can be used with most common safelights for black and white papers. Subsequently, LEDs also produce very little heat in operation, which can be very benefitial in a small, non air conditioned darkroom. Key Features. Such LEDs require no filtering and there is no filter factor light loss. By definition, the safelight is a light source emitting light in an area of the spectrum that does not affect the light sensitive materials for which it is designed. A classic interchangeable filter fixture with the corresponding filters for your processes is a comprehensive solution. Digging deeper, you will stumble upon safelights described as amber, brown, yellow-green and others. All other standard return policy conditions apply. Make your screen processing area "light safe" w hile handling light sensitive products. Well, yes and no.

This is more of a personal preference than anything else. A bare bulb incandescent or LED safelight is the easiest and cheapest option. Modern panchromatic photography film is sensitive to all parts of the visible light spectrum, so no safelight is suitable for it. Despite it’s traditional roots, analog photography benefits from the latest developments in lighting. Just like the interchangeable filter type, the filtering material of the bare bulb is also prone to fading, so testing and monitoring is, again, necessary. Making do with a dim bulb is a bit trickier. You might get lucky and it may just be the right spectrum to do the job, or it may ruin that precious box of Ilford paper. It provides illumination only from parts of the visible spectrum to which the photographic material in use is nearly, or completely insensitive. Safelights are also utilised in most other fascilities handling photosensitive materials like medical imagery labs (x-ray radiology), lithography printing outfits and others. However, any radiology technician should consult the film manufacturer’s guidelines before commiting to a working setup. For direct lighting, do not expose the paper to the safelight for more than 4 minutes, and the distance between the paper and the safelight should be a minimum of 1.2 metres/4ft. It’s a good practice to always do your own tests before you commit to any serious darkroom work with new equipment and/or materials. Filter manufacturers provide guidelines, but testing with your particular setup and materials is best. Choosing the right safelight is only one step of the way to a successful print. 16 Reviews.

The humanly visible portion of the light spectrum covers a wave-length range from approximately 380 nm up to 780 nm. A safelight usually consists of an ordinary light bulb in a housing closed off by a coloured filter, but sometimes a special light bulb or fluorescent tube with suitable filter material coated directly on the glass is used in an ordinary fixture.
