In the history of modern photography mankind has accumulated an enormous collection of photographic material. A large part of this collection consists of transparent material (e.g. Glass plate, acetate, nitrate, celluloid based material and slides). Most of the time only a selection was made from this material. By now it's clear that this material isn't going to last forever. In search for a cost effective way of preserving this material we can use digital equipment to make a copy. Technology has made such huge advancements in resolution and color accuracy that we are able to put it to our advantage. Having gained a wealth of experience in the last 2 years in a Dutch project called ‘Images for the Future’ (the digitization of over 2 million transparent images) we are now ready for the next step in large scale digitization of transparent photographic material.
