Say I have 5 different folders over 3 drives that contain pictures exhibited at a certain gallery over the years. I navigate to one of these folders, select all the thumbnails in the folder, go to Library>New Collection.
The resulting dialog box offers the options of: 1) Include Selected Photos, and, 2) Make New Virtual Photos. Both can be checked simultaneously. What are the differences using 1, 2, and 1 + 2? What happens when I navigate to the next folder with my pix? Do I just select and drag them into the new collection in the left panel?
If I then go to the new collection and work on one of the images, would I be working on an original image? If I then edited it in Photoshop and saved it under a new name would it be saved into the original folder? Would it be in the collection as well?
