Non-Destructive Editing.

Non-Destructive Editing.

Define 'Non Destructive Imaging (NDI)'

NDI referes to image processes where the source image may be adjusted in a way that leaves the original data intact. (Krogh. P, An evolution of rendering technology, pg 1)

The most simple way of putting NDI, is that in post processing you create layers on layers to ensure that the original data is kept intact, giving you as much colour and other information as possible. As when you start to process your source image, you start to lose data that can then not be recovered.

List four challenges introduced by digital photography

1. The need for a single source image being show in more than one way

2.  Being able to make changes to a group of photos in one go

3. The large amount/numbers of photos

4. Keeping up with technology/software in the future.  

What is meant by a 'Derivative File?

Copy of the original file, with all the changes saved, using the 'save as' after each change is made, making a new version of the original image, so you can keep the file or original image and letting you to go back to whatever change you want.

What are two problems with using "Save As' to create derivative files?

1. Saving to Meany files that could confuse you, taking up a lot of room saving it again and again. 

What is 'Self Referenced Non Destructive Imaging'?  

Photoshop makes a layer or preview file on top of the original, so the image can be preserved.  

List two advantages of 'Self Referenced NDI' over the use of Derivative Files?

1. They take up less room

2. See what changes you have made and letting you go back to them later

Define 'Parametric Image Editing (PIE)'

Software that thinks the original will not be changed, instead saved different copies when the file is being saved. 

What is the difference between a 'Live Rendering' and a 'Fixed Rendering'?

•   Live Rendering is a view of the image that only exists when the source image is loaded into the software. Like the light room photo or Photoshop with all your layers

•   A fixed Rendering is the final image flatted for printing

List three advantages of NDI

1. Money and time

2. And better for your image
