Imaging: Learning Units

1. Vision and Digital Imaging

We learn about the relationship between visual perception and the binary encoding of light.

2. Imaging Overview

We learn about the international structure of imaging standards, guidelines, and ethics for producing archival master images.

3. Physical Care & Handling

We learn about handling materials safely and discuss some myths about light exposure.

4. Imaging Hardware Options

We learn about the fundamentals of scanners, viewing conditions, and lighting.

5. Imaging Software

We learn how to operate scan control software and the roles that software tools play in digitization workflows.

6. Outsourcing Digital Imaging

We learn how to discuss digital imaging with third-party vendors.

7. Error & System Performance

We explore an ontology of imaging error and learn how to test imaging system performance using standardized test targets and OpenDICE software.

8. Resolution

We learn about Spatial Frequency Response and how to measure the capabilities of scanning equipment to meet quality expectations.

9. Tone Response

We learn about the Opto-Electronic Conversion Function (OECF) for image tone/exposure and white balance/neutrality.

10. Color Accuracy

We introduce Delta E and the fundamentals of visible color space and learn how to estimate the accuracy of color encoding.

11. Archival Image Formats

We learn about the TIFF and JPEG2000 file formats.

12. Post-scan Image Processing

We explore the ethics and procedures surrounding the normalization of archival masters and the production of derivatives.

13. Image Metadata Standards

We learn about documenting the technical features of images inside and outside the file.

14. Future of Digital Imaging

We consider the technical trends that are changing digital imaging.
