I hope it works. I must make a comment here because I have been
preaching about the possibility of playing phoyographs of records for 40
years. I realized around 1970 as I took photos of journal pages and
paper files to use as microfilm as a replacement for notetaking while
researching for my PhD. dissertation that it was great that I could
capture the page in an instant and read it later but when I took
pictures of records I could only read the label info, not hear it. No
instant capturing of the sound. Dubs had to be real-time. But I was
sure that if the pictures could be taken so that the record was evenly
lit -- like using a ring light around the lens -- and not have wedges of
light, the sound could probably *someday* be played.
When the design for the photographic system for the Rigler Deutsch
Record Index was being developed I pleaded with them to light the discs
evenly. But their ONLY concern was legibility of the label and the
matrix number markings. But there are now unplayable photographs of
700,000 78s in the RDRI films. (For those who do not know, the records
were photographed and the data entered into the computer from the
films. Instead of the records being moved to the computer in those days
of the mainframe, the special camera came to the archuve.)
