EditportQuote Does diacetate film naturally stink of mothballs as it ages? Or has the film just been stored in a humidor can with a preservative in it? Examples of humidor film cans... From what I gather, the humidor film can was used for added humidity via water and not chemicals. But maybe they used the humidor cans for both. Photos: Daniel D. Teoli Jr. Archival Collection Here is what AI says about the mothball smell... Diacetate film, in the context of photographic and motion picture film, refers to a type of cellulose acetate base where two of the three hydroxyl groups on each glucose unit of the cellulose molecule have been replaced with acetyl groups. It was an early form of safety film, replacing the highly flammable nitrate film, and was used extensively in the early 20th century. Diacetate film is characterized by a characteristic smell of camphor or moth balls, and while it was a significant improvement over nitrate film, it did have some stability issues like shrinking and embrittlement, leading to its replacement by cellulose triacetate. Key Characteristics and History: Development: Diacetate film was developed by chemists in the early 20th century as a less flammable alternative to nitrate film. Chemical Composition: It's a cellulose acetate polymer where two of the three possible sites on each glucose unit are acetylated, according to the National Film and Sound Archive of Australia. Early Use: It was used in both sheet and roll film, particularly for 16mm cinema films, as noted by the National Archives. Limitations: Diacetate film did suffer from issues like shrinking, embrittlement, and distortion, leading to its eventual replacement by cellulose triacetate. "Vinegar Syndrome": Like other cellulose acetates, diacetate film is susceptible to "vinegar syndrome," a condition where it deteriorates due to the release of acetic acid, resulting in a vinegar smell, shrinkage, brittleness, and the formation of crystals. I'm thinking if the mothball smell is not a preservative, but a sign of deterioration; the reels need to be permanently aired out or at least stored in ventilated cans to de-gas. I have always kept them in non-ventilated metal cans thinking they were embalmed! Daniel D. Teoli Jr. Archival Collection Daniel D. Teoli Jr. Small Gauge Film Archive Daniel D.

They called LaserDiscs, videodiscs back in the day. They also had VCD or Video Compact Disc. They were video on CD discs. Laserdisc Rot Article Video Magazine 4.87 D. D. Teoli Jr. A. C. : D. D.

The upper disc is suffering from bronzing which caused disc rot. Light and heat causes bronzing and makes the disc unreadable. The lower disc is the same brand media and age as the top disc. It was stored in climate controlled dark storage; whereas top disc was stored in heat and light. <><><><> Daniel D. Teoli Jr. Archival Collection Daniel D.

I routinely weigh down the scanner lid with an extra hard foam backer to flatten out warped archival material tight on the scanner glass. In the old days we had vacuum frames to flatten things out...perfectly! I've had no trouble with using 16 - 18 pounds on the glass for years. Today I tried 22 pounds on an Epson V600 and it started to break. When I get a chance, I will write up a proper report, but too busy right now scanning! Be careful how much weight you put on your flatbed scanner...they will break! <><><><> RPPC - Raw Scan Oil wells Pacific Coast Highway Huntington Beach DDTJRAC

I have a large collection of historic full-size front-page headline newspapers in the collection. I haven't counted them, but maybe there are 1200 to 1600 pages I have a smaller Kaiser copy stand that goes up to 40 inches. But I need a stand that goes to 60 inches or thereabouts for the newspapers. Large format Kaiser copy stands are stupendous in price. This motorized stand is $16K Here is an interesting idea for a cheap copy stand. But it is too small for my use. If it was upscaled and could handle a heavy camera it would be great for the cost. This is like $200. Just depends on how steady it is. Every Kaiser stand I've used is rock steady! And it is not that I just need to do a half ass job with the digitization as many people do. I don't like to sign my name to shitty work. Any archival work I do has to be top shelf or as close to possible to top shelf as the budget allows. We never know when out work will be the last extant copy for the historical record. I was thinking something like this square pipe rig could be made with 2-inch round galvanized pipe. But attaching the camera has to be figured out. Have you ever made a large format copy stand? I also need a vacuum easel. Years ago, I had built a vacuum frame for some copy stand work I was doing, but it is too small for newspapers. <><><><> Selection from Twenty-six Roadkills (2014) artist's book by Daniel D.

I'm testing how long SDD drives hold data without being plugged in. First part of the test is complete. 11 months for a Samsung T7 was OK. Next test is due early 2024. I have enough Samsung drives to go out for a few years of tests. I had heard they lose data if not plugged in periodically. The 'how often' part is up in the air. I've tested SD cards and they hold data pretty good. Also testing thumb drives, going out to 14 years...if I live that long. Here are some SD card tests. SD Card Report…how archival are they? – Daniel D. Teoli Jr. Archival Collection – II (home.blog) Will update thread as SDD drives are tested.

Free download... Found it at the Large Format Forum. I won't post their link because the bastards banned me numerous times...but I hold no prejudice and will give them credit for the source. The Permanence and Care of Color Photographs: Traditional and Digital Color Prints, Color Negatives, Slides, and Motion Pictures by Henry Wilhelm with contributing author Carol Brower http://www.wilhelm-research.com/pdf/HW_Book_761_Pages_HiRes_v1c.pdf The Internet Archive has a copy of it, but you have to borrow it by the hour. Crazy! I was going to upload to the I.A., but was worried someone would complain and take it down. I had spent a month scanning + another month uploading 3,000+ pages of 1970's Playboy VIP Club magazines to the I.A. One day, Playboy complained about the material, and it was all taken down. The I.A. would have normally banned me for that and was lucky they didn't delete my hundreds of thousands of other scans. But that is how the shits in Frisco think. One offense and they kill it all. So. I don't want to push my luck. Everything the archivist deals with is more or less copyrighted. It is the archivist's job to determine whether it falls in the area of the greater good or the greater right. Agfa color photo paper 6 Months Sun Fade Test Selection from Dye Stability Testing of Color Imaging Media II by Daniel D. Teoli Jr. I had an outstanding website dedicated to dye stability testing of color imaging media at Tumblr for many years. But they deleted it along with the rest of my 49 websites in 2019. All the fade testing material was lost. I still have most of the scans, but have not had any time to recreate it. My fade testing is basic and to the point as opposed to Wilhelm's method. Still, Wilhelm has some good fade photos in his book, but also lots of graphs and charts. Well, 700+ pages of material, so something for everyone, whether you like photos or are of the anal 'graph and chart' nature. Also, lots of photos not related to fading and also some cine' related photos. Wilhelm used controlled fading with a room full of lights on 24 hours a day. I could not afford a room full of lights, a room to store them in nor the electric bill running the lights day and night for a decade or more. So, I used Bob Pace's method of sun testing. I also like my method of cutting material into 2 pieces and fade testing one part of it. 6-month sun fade test of a dye-based print made on a Canon MG2522 printer.

Kodak (Mexico?) Inkjet Paper Deterioration See yellowing edge of paper compared to white paper. The entire sheet of Kodak paper has yellow blotchiness. The edge is the easiest way to see the yellowing in a photo. If you have a laptop or unbalanced monitor, you may not be able to see the yellowing. This was Kodak's cheapest paper at the time. From what I recall, the paper was made in Mexico. Paper shown here is 10 years old, stored under normal household conditions. It started to show yellowing about 3 to 4 years ago. All of the rest of this Kodak paper shows the same yellowing. It is hard to get a good photo or scan of the yellowing, but it is easily detected by looking at it under 5,000k lighting. A couple of other major photo paper makers also suffered from yellowing of their cheapest brand of inkjet paper. I didn't record the maker's names. I didn't purchase this paper to print on. I didn't purchase this paper to do archival testing. All these papers were purchased to use as interleaf while printing artist books with an inkjet printer. Unless interleaf was used while printing, the pages would transfer freshly printed ink to the page stacked on it. This was a big problem when using matte black ink, but not a problem with gloss black ink. RC gloss or RC semi-gloss inkjet paper worked best as interleaf as it did not accept any ink transference on the RC coated verso of the paper. <><><><> Daniel D.
