Non-Destructive Image Editing

Part I – The Evolution of Non-Destructive Imaging

1. Define ‘Non Destructive Imaging’

Non Destructive Imageing refers to imaging processes where the source image may be adjusted in

a way that leaves the original data intact

2. List four challenges introduced by digital photography :-
1. Storage space for digital files
2. Keeping up with the latest soft ware
3. Backing up images
4. What type of format to use for your image
3. What is meant by a ‘Derivative File’ ?

You may have a copy or a edit of the original, that is a derivative file because it has been derived from the original

4. What are two problems with using ‘Save As …’ to create derivative files ?
1. Confusion could occur because if saving multiple times to explore different aspects of the image
2. it may create storage problems if saving the same image multiple times
5. What is ‘Self Referenced Non Destructive Imaging’ ?

This term is used for haveing multiple layers on the same image, so instead of changing the image itself you could create layers to work with

6. List two advantages of Self Referenced NDI over the use of Derivative Files :-
1. Its much more ecumenical space wize because the instructions for editing a file take up less room. where the use of the additional derivative file is the size of a normal picture
2. The use of layers to it makes it easier to go back and recorrect mistakes and what not
7. Define ‘Parametric Image Editing’ :- any form of instruction that records information

8. What is the difference between a Live Rendering and a Fixed Rendering ?

Fixed rendering refers to a image that has its information in pixels and dosent need a engine to do what user wishes with the image

9. List three advantages of NDI :-
1. Make changes to a image and not have to worrie about looseing the original file

b. Takes up less space
