Questions Part I – The Evolution of Non-Destructive Imaging
1. Define ‘Non Destructive Imaging’
NDE refers to an imaging process in which the original image’s data is left untouched.
2. List four challenges introduced by digital photography :-
a. The creation of large amounts of photos
b. The need to apply the same adjustments to multiple images
c. The need to create multiple versions of 1 photo. EG black and white, colour
d. The desire to take advantage of new and improved software
3. What is meant by a ‘Derivative File’ ?
A version of a photo file that has some adjustments incorporated.
4. What are two problems with using ‘Save As …’ to create derivative files ?
a. Take up more space on the hard drive
b. Confusing to keep track of the images
5. What is ‘Self Referenced Non Destructive Imaging’ ?
An image which contains multiple versions of itself stored in its file. For example PSD files contain layers.
6. List two advantages of Self Referenced NDI over the use of Derivative Files :-
a. Easier to store. Doesn’t take up as much of your hard drive
b. Easier to sort out what has been done.
7. Define ‘Parametric Image Editing’ :-
A set of instructions attached to an image
8. What is the difference between a Live Rendering and a Fixed Rendering ?
A fixed rendering refers to an image which is described in an RGB or greyscale value. Live rendering is used when opening a raw file. It translates the data to data which shows an image on the monitor.
9. List three advantages of NDI :-
a. Able to view the original file
b. Easier to make adjustments
c. Generally smaller file size

Part II – The Rendering Engine
1. What is a Rendering Engine ?
A piece of software that renders your image based on a set of settings.
2. What three things determine the final colour of an image pixel ?
a. Original image data
b. Rendering engine
c. Settings applied by the user to the rendering software
3. What are the three main components of a RAW file ?
a. Jpeg Preview
b. Metadata
c. Mosaiced raw image
4. Can PIE software be used only on Raw files ? No
5. What is a Live Rendering ?
A live rendering is a view of the image that only exists when the source image is loaded into the software.
6. Where can the Rendering Metadata be stored ?
a. Inside the file
b. An XMP file
c. Catalogue
7. Give two examples of a Fixed Rendering
a. RGB File b. Greyscale File
8. Is a Preview a Live or a Fixed Rendering of the image ? Live Rendering
9. Where can Previews be stored ?
a. File Browser
b. Catalogue
c. Inside a Raw file
10. Why do File Browsers and Cataloguing software create Previews ?
To speed up the display of photos.

Part III – Catalogue-Based Non-Destructive Imaging
1. What model does cataloguing software use ?
A Library Model
2. Where are the images stored in a catalogue based system ?
The images can be stored in 1 folder, or multiple folders.
3. Where does the catalogue get its initial information about the files ?
From the Metedata of the original files
4. Where does the cataloguing software store this information ?
In Its catalogue
5. What is the main organising principle of Browser based systems ?
Browser based systems cache there information in databases.
6. How do cataloguing systems organise their images ?
By using Metadata
7. How does a cataloguing system make changes to an image ?
Through Metadata
8. Can other programs see these changes ? Yes
9. How does a cataloguing system make changes to an image available to other programs ?
Through the metadata in the catalogue
10. List 5 advantages of Cataloguing based PIE software ?
a. Associates information with one original file
b. Creates groups from scattered images
c. Works with offline images
d. Easy to backup and restore tasks
e. Generates multiple output types
11. Give two examples of software that combine Image Cataloguing and Editing functions ?
a. Lightroom
b. Aperture
