Scanning Into Aperture Cards (This article is not about using Apple Aperture flat bed scanners.)
What steps go into aperture card scanning? First, you have to ask yourself or your client: how will the
aperture cards be retrieved in digital format? Do you need to convert
aperture cards to PDF or TIFF? Shall the apertures be multi-page or single page? Will the hollerith code punches be used to index and name the images? What if there are no hollerith punches? Are the aperture card drawing names typed on the title of the card and/or on the images themselves? What are the different size drawing contained in your aperture card collection (A-E). Do the images need to be autocropped or cropped manually?
All of these questions will help in the initial phase of a large aperture card set.
