Instructions	Read the article provided – ‘Non-Destructive Imaging: An Evolution of Rendering Technology’  by Peter Krogh - and answer the following questions in the space provided.
	Part II – The Rendering Engine What is a Rendering Engine ? It is software that converts/decodes RAW file information so the image can be displayed                                                                                                                                                                                            What three things determine the final colour of an image pixel ? Original Image data                                                                                                           the rendering engine’s mathematical formulas                                                        settings applied by the user to the rendering software                                           What are the three main components of a RAW file ? Mosaiced Raw Image                                                                                                       Metadata                                                                                                                              JPEG Preview                                                                                                                      Can PIE software be used only on Raw files ?                       No (used on any files) What is a Live Rendering ? A view of the image that only exists when the source image is loaded into the software.                                                                                                                                                                                              Where can the Rendering Metadata be stored ? Inside the file     (not used with RAW)                                                                                                                   in a sidecar file                                                                                                                   in a database or catalogue                                                                                                                      Give two examples of a Fixed Rendering Derivative file (ie web gallery)             b.    Prints                                                         Is a Preview a Live or a Fixed Rendering of the image ?  Neither it is a semi-permanent Fixed Rendering in jpg format                         Where can Previews be stored? Raw files created by digital cameras must have a preview nside the raw file itself.                                                                                                                                                Alongside the image file                                                       Catalogueing software makes previews                                                                     Why do File Browsers and Cataloguing software create Previews ? To boost speed of operations
