IRENE (Image, Reconstruct, Erase Noise, Etc.) is a digital imaging technology designed to recover analog audio stored on fragile or deteriorating phonograph cylinders, records, and other grooved audio media!

That's an excellent question! The decision not to use gloves in conservation often comes down to balancing the preservation needs of the object with the ability to handle it effectively. While gloves can prevent oils and dirt from our hands from transferring to objects, they can also reduce tactile sensitivity, which is crucial for delicate handling. When conservationists use bare hands, they typically ensure that their hands are clean, dry, and free of oils or residues, which is often more beneficial for maintaining control during delicate tasks. However, gloves may still be used when handling certain materials that are more sensitive to oils or dirt. It really depends on the object and the task at hand!

Working on it!

Thanks for commenting! This technique is used to fill losses in paper, only when the paper is strong enough to withstand the treatment and when all media present has been tested and is shown to be insoluble in water. Documents of any age can withstand this treatment, however, it may not be considered appropriate for all materials depending on the nature of the object and treatment goals. As with all conservation treatment, both the paper and media must be tested beforehand to determine if this method can be used safely.

@@nedccenter Thank you!

@@nedccenter The Japanese use Tengujo paper with 3,5 GSM above and under the archive to gain additional strength. Invisible on the ink.

Happy to help! Here's a Preservation Leaflet on "Protection from Light Damage": www.nedcc.org/free-resources/preservation-leaflets/2.-the-environment/2.4-protection-from-light-damage.

In this instance, the custom box was ordered and then modified in house. We so also make custom boxes in house.

Tapes that pass PAT (Photographic Activity Test), however, it still poses the risk of adhesive migration, so choose your materials carefully and apply it with consideration for the long-term.

Our lead preparator and paper conservator addresses this later in the video: ua-cam.com/video/k6vzqz3DKgo/v-deo.htmlfeature=shared&t=188.

There are a number of trusted archival suppliers who sell four-flap enclosures and boxes, such as University Products, Gaylord Archival, Talas, and Hollinger MetalEdge, to name a few. NEDCC does not endorse any supplier in particular.

@@nedccenter thank you very much!

The easiest way I have found of doing this is placing the glass negative on a light board (light inside a box with white plastic on the top side where you place the negative). I then mount a digital camera over it on a tri-pod (camera tilted down to face the negative that is sitting on the light box). Put the camera in B&W mode and then take a picture of the negative (zoom in to fill as much of the screen as possible with the negative but without cropping it). Then load the picture into photoshop or some other tool that has the ability to convert a negative into a positive. You then have a nice digital picture of very high quality. I've printed as large as 20"x30" (poster size) from 5"x7" glass negatives with amazing results. I first thought using a scanner would be easiest but you first need to get a scanner that lights from the top down instead of from the bottom up. Then you have to keep the negative up off the glass a fraction of amount to avoid weird circles showing up on the scanned image. In the end, I just found the camera method to be faster and the quality was more than acceptable. I had 2,000 glass negatives to scan, so waiting the 20 seconds or so for the scanner to do its thing was just too long. I should point out that if you want something real quick (instant gratification) then just take a picture of the negative with your phone (negative still needs to be back lit) and then download free software from your app store that will convert a negative into a positive. I did that first just to get an idea of what some of the pictures were of. Its super fast but not what I would consider archival quality.
