institutes / laboratories analysis of photo materials
Hi everyone,
I work in a photographic archive, the archive contains approximately 50000 B/N microfilms, and approximately 20000 13x18 cm color slides. Are there research institutes or laboratories providing analysis of photographic materials ? I need to know which are the precise causes of deterioration of my photographic materials. Thanks in advance for any information. ....and sorry for my english... |
