We charge a usage fee per photo if the photo is published, reproduced in a product or publicly exhibited. This is not a license in the legal sense. As a non-profit institution, we do not make any money providing these photographs. It is only by assessing usage fees that we are able to cover the cost of providing publication quality copies of our photos, preserving the photograph collection according to archival standards, and providing access to the collection by maintaining an online image database. The copyright holder may charge a fee in addition to our service fee.

Images are for use in educational projects only and must be used in a respectful manner.

These two photographic prints are made from the same negative. The 'original', on the left, is made by ordinary photographic techniques. The photo on the right is made by scientists at Bell Laboratories using a new image storage device called a ferpic (ferroelectric picture device). The original negative is used as a transparency in a contact-printing technique, when the image is stored in the ferpic. After storage, the image, which is 5 mm high, is projected onto photographic material to produce the photo.
