Lecture 2 Flashcards
Digitization:
the process of re-representing non-digital material in digital form
Mass digitization:
digitizing huge amount of analog materials
Digital preservation:
ensuring the continued existence and usability of digital materials, no matter their origin
how do you digitize images
- With a digital camera, take a photo…or many
- Scan them with a piece of equipment called a scanner
- You often must correct issues with the original or problems with the scan
how do you digitize textual materials
- Transcribe them. Possible encode them (a bit like making a web page to record or more info about their structure or meaning
- Or scan them, just like an image, but then what the computer sees is an image of text, not actual text (you can’t search it or copy and paste)
how do you digitize sounds
Connect playback equipment to a computer, when possible (its not always. Some analog audio equipment is just that old) Ideally, you want to use an audio interface for higher quality sound than a typical sound card
how do you digitize video
Connect playback equipment to a computer where possible (again it isn’t always). The computer may need a special “video capture card”
how do you digitize film
- Buy a specialized film-digitization machine (very pricey) or…
- Buy a video transfer gadget, project the film into it, and capture the projected film on digital video (seriously people copy film with camcorders)
how do you digitize 3d materials
You put the object on/in a 3D scanner or digitizer (if it’s small enough) or you run a portable 3D scanner around it
Digitization Standards:
documents specifying what acceptable quality digitization is for a given type of analog material and how to do the digitization to achieve that quality- these standards are full of jargon
copyright
A complex of state, national, and international laws aimed at helping creators protect (in certain limited ways) and profit from creative
