FADGI Metrics for Still Images, Part 1
LYRASIS Webinar Series: FADGI (Federal Agencies Digitization Guidelines Initiative): Standards-Compliant Still Image Digitization
What makes an image a “good” image? How can image quality be measured in a standards-compliant, repeatable fashion? Digitization consumes resources, and there only may be a single opportunity to convert certain collections; how can we make sure that it is done in accordance with the relevant guidelines and that the digital assets created will endure over the long term? This series of five webinars will examine the Federal Agency Digitization Guidelines Initiative (FADGI) as it applies to still imaging for cultural heritage institutions. After an overview of FADGI, we will spend time reviewing each of its core metrics in detail, and share hands-on and practical applications of these metrics in real digitization projects.
This webinar series is most suitable for attendees with medium to advanced photographic knowledge, preferably those who have already been through several digitization projects. Previous hands-on experience with digital cameras / scanners and software such as Adobe Photoshop and Capture One Pro will be very helpful.
In this webinar, we begin an in-depth look at all of the FADGI metrics and how they individually affect still image digitization workflows. Don Williams will examine three of the metrics in detail: 1.Tone Response 2. White Balance 3.Uniformity
Jim Studnicki will discuss selecting (and keeping!) proper camera white balance, as well as using a luminosity mask to achieve a high degree of image uniformity.
