What is preservation and what is restoration?
1. PRESERVATION / ARCHIVAL is preservation of images / sound without manipulation. This could mean simply subjecting the best original element to highest quality long term storage conditions available. And further, funds permitting, production of best quality duplicate copies placed in highest quality long term storage conditions, which are completely separate and removed from the location of the original elements.
2. RESTORATION, is the correction of unintended defects which exist in an available original element so as to enable a best possible reproduction of the original viewing experience.
