A Digital Souvenir: The 1900 Automobile Club 1,000 Mile Trial

Technical Note

Table of Contents
This project was produced by Tori Cox, Russel Peterson, and Dana Reijerkerk as part of a master's level course in Digitization of Cultural Heritage Materials at the University of Michigan's School of Information.

The photographs used in this digital exhibit were originally situated within a souvenir photo album, with the words "Souvenir of Automobile Club 1,000 Mile Trial, 23rd April to 12th May, 1900" embossed on the front cover. Photos were attached to front-side of most pages with a few being on the back-side in instances where there was a panoramic shot. The cropped images that we included in our exhibit lost some of the materiality of the original work because we did not include the full image within the scrap book page. We wanted to allow a high resolution and quality image to have a zoom capability so we decided to edit out the scrap book page within all of our derivatives.

Below is one of our production master images from the photo album and also in our exhibit. In the far left of the image the binding of the scrap book can be seen as well as the size of the photograph in relation to the scrap book page. All photographs from the photo album were 11.25" x 9". Pages within the album were 14" x 10.37".




For the purposes of our project we used an Epson 11000XL Scanner to digitize our images, which we then tested the quality with Golden Thread. Post-processing was done through various softwares such as Golden Touch, IrfanView, Preview, and Photoshop. We also converted our images from JPEGs to TIFF's that would fit into the file size threshold of Scalar.

We based our technical specifications on the Technical Guidelines for the Still Image Digitization of Cultural Heritage Materials from the Federal Agencies Digital Guidelines Initiative (FADGI) working group. Below are the specific FADGI standards we to which we attempted to adhere. Our team aimed to achieve 4-star quality digitization, and thus manipulated any scanner settings within our control to meet the standards defined in this table. All images were scanned at 400ppi and 16-bit depth level. However, due to the capabilities of the scanner, portions of our image qualities (such as mean Delta E scores) were only able to meet 3-star standards.





Note on parameters and specifications we used. 



Note on the metadata we captured in our spreadsheet versus the metadata we put on scalar with each image.
