If you want images just for printing & web - JPGs will work just fine. Just rate your images that you want to keep, filter them by rating, select them all (ctrl+a) and then export them as 'original size' JPGs. See screenshot below.
First you will need to migrate your photos from the Hard Drive of your computer to the place you will be saving/backing up your images. Do this at the beginning of class- it could take a while! (most of you have them saved in Photo Vault or Pictures folder on your computer) Then you need to move your catalog there:
How do I move a catalog?
You can move your catalog to a different location on your computer's hard drive, to an external disk, or to another computer altogether. Simply use the Explorer (Windows) or Finder (Mac OS) to drag or copy the following files to the new location:
- Catalog: [catalog name].lrcat
- Previews: [catalog name] Previews.lrdata
- Smart Previews (Lightroom 5 and later): [catalog name] Smart Previews.lrdata
To transfer a catalog between a Windows computer and a Mac, copy your catalog, preview, and image files from the original computer onto a flash or other external drive. Then, attach that drive to the second computer and copy the files to the desired location on the second computer.
Below is a screenshot of all the steps - we will just be copying the files now > you move them later to a different computer. Move these files & folders to your G: Drive (if you are not a senior), a Thumb Drive, External Hard Drive or Google Drive Folder.
For the in depth explanation- Watch this video by Julieanne Kost - she will walk you step by step. (skip the 'download Lightroom' step)
