Working with Erin Bannister-Townsend and the Bodleian Libraries, we have been commissioned to complete the extensive document and audio-visual archive relating to the late Sir Roger Bannister. I first met the late Sir Roger Bannister, back in the Summer of 2016. The English middle-distance athlete and neurologist who ran the first sub-4-minute mile, requested our companies services to prepare his large family archive of audio-visuals to high quality digital files.  As much as I wished to talk to Sir Bannister about his 1952 Olympics in Helsinki, where he set his British record in the 1500 metres, he was more interested in myself as a businesswoman and our team, which I found very humbling. We had a really lovely time talking about the business and how we operate in the heritage sector. In July 2021 we were then asked by his daughter, Erin Bannister-Townsend to complete the remainder of the more personal archives for both her father, mother and relatives.   This archive comprised of

Difference Between 33, 45, and 78 Records? Our busy audio-visual studio works with clients on short order and batch order audio projects.  One project we are currently working on is a large archive of 78rpm disc records.   78s are made of brittle material, which use a shellac resin. Another name for 78s is Shellac Records. During and after the World War II when shellac supplies were limited, some 78rpms were pressed in vinyl instead of shellac (wax), in particular the 6-minute 12" produced by V-Disc for distribution to US troops in World War II.  The most common is the 10" and 12", both sold in  paper or card covers.   Our professional studio converts records on high quality record decks, using the best arms, cartridges and stylus. Audio is paased through our Pro-Tools and Izotope system, with the final output audio restored to remove pops, clicks and crackles (optional to clients requirements). The end result is high quality WAV, FLAC or AIFF beautiful digital files wit

We are currently working with a well-known UK fabric company preparing digital files from their range of materials for online presence and resale.   Not all scanners are ideal for this type of order due to colour and precision capture.  Our Quattro X though, is perfect for this type of project, and any professionals who require a high-quality scanner with excellent scan performances.   HIGH QUALITY SCANS AND COPIES Our scanner excels by using 48-bit technology.  This means we can capture every detail from fabrics, rare maps, oversize pages and documents to engineer plans in full colour or greyscale outputs.  The digitised media then passes the best 24-bits through at up to 1200dpi optical resolution to produce the highest quality outputs of your media.   Our CleanScan CIS modules also help remove shadows created by creases and folds, which makes this the ideal scanner for our client and other professionals who require precision scanning.

Acetate Film Base Beginning in the mid-1920s, highly flammable nitrate film was slowly replaced with cellulose acetate film base (cellulose diacetate, cellulose acetate propiarate, cellulose acetate butyrate and cellulose triacetate).  It became known as "Safety" film. Despite this name, cellulose acetates do have stability problems. Like cellulose nitrate, the deterioration of cellulose acetate is autocatalytic: once deterioration has begun, the degradation products induce further deterioration. It affects the plastic support of acetate film, causing it to become acidic, to shrink, and to give off of acetic acid producing a vinegary odor.  A useful tool in helping determine the amount of acid vapor present, and gain an overview of the condition of acid vapors in an entire collection are "A-D Strips" (acid-detecting strips). They are acid-base indicator papers, which turn from blue to green to yellow in the presence of acid, and measure the extent of the acetate bas
