Library Archive Prints Scanning Project


In order to digitally scan the print images and to maintain a catalogue filing system parallel to that of the original Library print folders, the following procedure is recommended.

The existing prints from the 1960s photographic survey of central Bradford prior to its demolition and rebuilding are contained in approx 25 plastic sleeved folders.

Each folder contains approx. Thirty-six 8x6 inches b/w prints of varying quality but of major local history, architectural and social history importance..
Each folder is numbered and has the title of the area/district covered by the photos. Each prints carries its own unique catalogue reference number and a brief description on the back.

The prints are stored back to back in an inner clear plastic sleeve which is inserted 'open end' down into the sleeve pockets of the folder - the photos are then secure and cannot slip out.

Scanning Procedure
Carefully remove prints (a pair at a time) from folder inner sleeves.
Scan individually as 'Greyscale' (not colour) at 300dpi.
Crop to a tidy landscape or portrait format excluding any white border.
(Note: The prints vary as to the border size and accuracy of cut edges, ie. image not always parallel to the print paper edge.)

A typical Greyscale image scan will be approx. 2500px wide x 1700px high with a file size of approx. 4 Megabyte dependant on amount of fine detail contained in the image. If your sizes vary greatly from these guide figures, then you are doing something wrong.

Saving Image
Save as a TIFF (Tagged Image File Format) uncompressed with a filename of the form . . .
Print Number brief title
eg. 12-6 James Gate

MS Windows will automatically add the '.tif' filename extension.

Store images on your hard drive or external flash drive until the whole print folder is is completed. They can then be burned to a CD Rom disc.
When storing image scans create a new folder with the same same as the print folder, eg. Book 3. Inside the folder create two new folders and label TIFF and JPEG respectively.
Your scanned TIFF images can now be saved in the TIFF sub-folder.
Repeat for all remaining prints/images.

Indexing Images
As the image filenames will have been shortened to allow compatibility between older versions of MS Windows and more importantly across other computer platforms and older (legacy) software, it is advantageous to have a plain text file Index of print scans with more detail of each image.

Open MS Notepad and create a plain text file of the form . . .
Book No.
Area Covered by images

Image No, Description, date, copyright if known
Arrange in pairs (with blank line above and below) to match photo pairs in Library print folders.

Eg: Book 3

12-4   James Gate/James St. junction, 1963
12-6   James Gate - towards Westgate, Aug 1966 (c)T&A

At end finish with . . .
Your initials/date
eg. CLS/April 2007

This is the only identification of who did the scanning and compilation of the images.

Save the file as 'Index'
MS Windows will add the '.txt' file extension automatically.
Store the Index file in both the TIFF and JPEG folders.

JPEG Preview Images
As the TIFF files are large it would take some time to open up over 30 and slow down the computer. It is an advantage to have a reduced sized version in JPEG file format with the maximum dimensions of 1024px wide for landscape images and 768px high for vertical (portrait) images. The JPEG versions are enhanced by having a white border of 5px thickness on all four sides. This will have to be taken into account when resizing to the maximum sizes given above.

The JPEG versions have the same file names as the TIFF versions from which they were derived. MS Windows will automatically add the '.jpg' file extension.
These JPEG images will load quickly to provide thumbnail images on screen and will run as an automatic slideshow by default in Windows.
