A Quality Index of 5 or better for visual images is required. In the first year of the project, participating libraries created TIFF images and submitted them to FCLA, which subsequently created PDF and JPEG derivatives. TIFFs are archived as uncompressed electronic masters. Color images are created and maintained in the sRGB color-space. Both grey and color images are calibrated and scanned to within the tolerances promulgated by the Library of Congress for the American Memory project.
Images created from microfilmed sources reflect the quality of the source microfilm.
TIFF images are used to create JPEG derivatives using Adobe ImageReady Version 2.0 in a batch executable process. The TIFF image is resized setting the width to 600 pixels and the height accordingly. The process then progressively optimizes the image creating an image that displays progressively in a Web browser. The image will display as a series of overlays, enabling viewers to see a low-resolution version of the image before it downloads completely. Creation of PDF files is a function performed by the locally written Florida Heritage loader software.
