Digital photographers, image managers, artists, instructors who teach with digital images, and various commercial and non-profit entities who solicit digital image submissions all care about the quality and consistency of digital images as they transfer among devices, formats, and platforms. The Universal Photographic Digital Imaging Guidelines (UPDIG) working group maintains excellent information for all of these interested parties. This group, a consortium of digital imaging professionals, related trade groups, and manufacturers, exists to promote international standards and best practices in digital imaging. The UPDIG guidelines are available in PDF or HTML format, and address digital asset management, color profiling, metadata, and photography workflow (note that UPDIG recommends the PDF files for their superior formatting and readability).
The Universal Quick Guide is an introductory overview on color management, monitor calibration, color space, resolution, file formats, file naming, sharpening, embedded metadata, file delivery, CMYK guide prints and verifiable proofs, archiving, and digital imaging workflow. The Photographers Guidelines explore these topics in much greater depth.
The Image Receivers Guidelines exist to address the common problem of inconsistency in digital image submissions. As noted in the "about" section of the document, "while end users usually have specific criteria for image submission, they often lack clear, consistent terminology for communicating those guidelines. As a result, photographers submit digital images in a variety of image formats, with various resolutions, camera types, color profiles, metadata schemas, sharpening and tonal correction." This document intends to help those who accept image submissions establish specific guidelines, with a recommendation for presenting a checklist based on best practices contained in the report.
