Noon-Detructive Editing. Part 3.

What model does cataloguing software use ?

The Library Model – it creates a catalogue or database and stores the metadata associated image, a preview and any other information contained with the image. It does not open the image but grabs the data and preview from the catalogue and not the hard drive where the RAW images are saved.  

Where are the images stored in a catalogue based system ?

Anywhere within your computer system, USB, DVD, CD drive – does not matter as lightroom reads the data and imports it into the catalogue where is stores for future use. Cannot go into develop mode if the RAW files are external.   

Where does the catalogue get its initial information about the files ?

From the metadata, will grab info from anywhere and import it into the catalogue. 

Where does the cataloguing software store this information ?

IN the catalogue 

What is the main organising principle of Browser based systems ?

It used the file system you have created on your computer, it does not create anything it just looks and what you have created. 

How do cataloguing systems organise their images ?

You have to supply it with Metadata, no metadata then you will have trouble finding images. 

How does a cataloguing system make changes to an image ?

It uses your instructions saved as metadata 

Can other programs see these changes ? - In general No as any changes are saved in the metadata in the catalogue as your working within the catalogue – Yes but this is a preference were meta data is saved into the DNG file as an xmp file. (make sure this is ticked off in preferences)  

How does a cataloguing system make changes to an image available to other programs ?

You have to create a derivative file in order for other programs to view the changes made within the catalogue.
