    I have been trying to understand the basics of how the software works. It seems Lightroom is a database program that modifies copies of image files for a particular result. The original files from my understanding are never touched only the copies. I believe when Lightroom starts I choose the Source of the images and the destination of the adjusted contents. Catalogs are the collections of the adjusted/modified data recorded by Lightroom at a location of my choosing. I choose to Source my image files from an external device and store the Catalog (which I name) on the same external device. When I open Lightroom I double click the Catalog and Lightroom opens that Catalog or collection of data concerning the adjusted images. When I wish to export the final edited data file I can choose what format, namely .tiff, jpeg or whatever. Is this accurate ?

    thanks -

    yep; pretty close as far as I can see --- the gurus might pick up on something

    The big one is not to move photo files in windows --- always use LR to moves file and folders
    Maybe too late --- import a small number of files and folders into LR to learn the basics and set things up with those file. Once you have good enough understand move in more files -- I would suggest moving the more recent files and slowly moving back through the older files. Great time to do some sorting/deleting.
    Have ONE main Photos folder and add required sub folders to that one folder
    Have just ONE catalogue
    I would also suggest a good book . Victoria's free ebook www.lightroomqueen.com/shop/adobe-lightroom-cc6-missing-faq/ will get you started but a full book is a good investment to save doing your head in totally ---- lR can be like that at time haha

    And ask questions before stuffing up your system --- many of us wish we did that !!

    Lets tweak some of your statements for a better understanding of how LR works.
    Lightroom writes everything to a database file. When an image file is imported, it is imported in one of two ways. 1. The original file already on your disk drive can become your master copy and stays where it is. LR stores a reference to that location. 2. Your original file is on a camera card. LR makes a copy of that image file and stored it in the designated destination folder. LR stores a reference to that destination folder location. This copy then becomes your master image file copy and you are free to erase the camera card. In other case, the pixels in image files stored in the reference location are not altered. That does not mean that LR does not touch these files. It can update the metadata in the file header.
    The Catalog is a database of information about the images in its inventory. We have already touched upon the reference location as one of this pieces of information. Other information includes keywords, labels ratings, Titles, Captions etc. Membership in Collections is another type of information. A collection called "My Vacation" can include images taken on your holiday. Some of those images could be in a collection called "Paris,France". If you assign a keyword phrase "Paris France" to every image taken in that city. you can find all of these images with a simple database query. They might be scattered in folders all across your internal and external drives.
    Perhaps the most important pieces of information about an image are the develop instructions. Things like where to position the crop window, Adjust the exposure, etc. Overtime you view an image, LR will take the original pixel image and adjust it in the computer to apply those develop instruction to show you the result on the screen. But if you want to show those results on MY screen you need to create a derivative file and send it to me or anyone else that might not have LR. This is the Export process where the original image and the develop instructions are merged and save into a new image file. You can take this original image and apply different develop instructions and generate several different derivative image files from the same original.

    Two things to remember. LR does not store your images. Only reference pointers to them And LR does not apply develop adjustments to the image, only to Exported images and to Images that you print using the LR Print module.

    Ian has good sound advice that I am sure came from the experience gained from making mistakes. Some of the same mistakes that I made too along the way. Remember that most mistakes can be corrected. But like the advice given of not moving your master image files in Windows after LR has stored the reference location. Some corrections are harder to fix than others.
