Slide1

DIGITAL IMAGES IN EDUCATIONLectures & presentationsSlide2

A little about youWhat disciplines do you work in?

What tools do you use to search for images?How do you look for images?

Do you start with a topic or a subject? Do you want an image of a particular person?Or do you have a specific work of art/photograph/image in mind?For what purpose?

Presentation? Article illustration? Book cover?Slide3

ResolutionResolution—usually expressed as the density of elements, such as pixels, within a specific area—is a term that many find

confusing.This is partly because the term can refer to several different things: screen resolution, monitor resolution,

printer resolution, capture resolution, optical resolution, interpolated resolution,

output resolution

, and so on. The confusion is exacerbated by the general adoption of the dpi (dots per inch) unit (which originated as a printing term) as a catchall measurement for all forms of resolution

.Slide4

ResolutionScreen resolution refers to the number of pixels shown on the entire screen of a computer monitor and may be more precisely described in pixels per inch (

ppi) than dots per inch (dpi) (ex. 3,000 x 2,000

ppi)(or for example: the new 27” iMac has a Retina 5K display of 5120 x 2880 ppi) – my old 27” iMac from 2010 is 2560 x 1440)

For more information on digital images see:

Introduction to Imaging (2003)Slide5

File FormatsTIFF, or Tagged Image File Format, has many desirable properties for preservation purposes (archival, uncompressed)

The JPEG (Joint Photographers Experts Group) format is generally used for online presentation because its compression is extremely efficient while still giving acceptable image quality (compressed, lossy

)Use JPEG images for your presentations (TIFF’s will be too large)Slide6

Image SizeFor full-screen display (in PPT) the images should be

1024 x 768 ppiDo not choose a smaller image and try to make it larger (it will become pixelated and lose quality)

The general image search engines are fine, as far as they go, and

some of them are even fun to play around with. But more often than not, the images you pull up this way are not

good enough for a

PPT

presentation, never mind for embedding in a paper or thesis, and

many

are

protected by copyright or licensing agreements

, which means

the

owners expect you to ask their permission prior to downloading and

using

those images in other ways.

While

this may not always be legally

necessary

, it is good scholarly manners to get in to the habit of, first,

making

note of where you find images; second, asking the content holder

whether

or not it is OK to use the images in the way you want; and third,

developing

the habit of citing your images in the same way you cite text quotes. Slide23

What does access mean?Different uses of the term “open access”Open access in the journal world: different levels, but can be understood as eliminating a

gatekeeperFor images, can mean:available to view onlineare free to

downloadare high resolutionfree to publish [what this presentation focuses on]Slide24

Terminology: licenses and codesIn many collections, you will find a mix of open and restricted images.

Terms to look for (examples to follow)Creative Commons licensesPublic Domain“For educational use only”

I encourage you to read the CAA Code of Best Practices in Fair Use in the Visual Arts

Image credit: http://www.collegeart.org/fair-use/Slide25

Code of Best Practices

in Fair Use for the Visual Arts

“FOUR FACTORS”

1. Purpose of the use

2. Kind of work used

3. Amount used

4. Effect on the marketSlide26

Public DomainSomething that is no longer protected by copyright law.The “commons”Tricky to figure out what is in the public domain, because it depends on country’s copyright laws

Also in the public domain: anything produced by an official of the United States government as part of their jobReal case scenario –

”Grab that image off the photographer’s web site” (??????)Slide27

Public DomainFor works produced in the US: generally, copyrighted works produced before 1923 since the term has expired. But it’s way more complicated:

Images Cleared for Scholarly Publishing

These images are rights-cleared for scholarly publications specifically.May be public domain or more recent images—not a whole lot of these, though

attributions (like those given in this presentation), there is no set

rule.Elements you might include:
