The following represents specific standards adopted by SCETI in their capture of digital images.
- Archival Masters: 600 ppi 24-bit raw TIFF color image
- "Golden Thread" color target is used for every exposure. Target also includes interference pattern and inch/centimeter markings. Target is also used to check focus.
Imaging and processing equipment
- Cameras: IQ280 80 megapixel Phase One digital camera
- Lenses: Schneider Kreuznach lenses
- Software: Phase One Capture One Pro; Photoshop CS3
Master images are captured at a resolution of at least 600 pixels per inch of the image subject. Once all of the images for a manuscript have been captured they are color-corrected, deskewed, and cropped.
In 2015, SCETI began using IQ280 Phase One digital cameras; however,
OPenn contains images that were captured using different equipment
before this time. If you have questions about a specific manuscript or
image, please refer to the header of the Master image or images in
