Managing version sets
I am not sure how this has happened, but my catalog has a number of photos with icons in the top right corner which I took to mean stacks. But in using the Find/stacks command, I found I actually have none. They are version sets. Whatever that is. When I use Ctrl D to change the grid, I see a small arrow on the right hand side of the picture, about midway down. Clicking on the very first one on the list, it appears to be the same photo, with a different orientation.
Some questions:
1) is there some reason why I would need both orientations?
2) are version sets limited to two versions for each photo? If not, how do I tell which photos are "versions" of the main one? (In my grid, Version set A seems to be parked right next to Version set B, so I am not sure where one stops and the other begins)
3) if the photos are always identical (are they?), is there some single command that will remove the unnecessary versions? Will this affect the thumbnail links to the "main" or principal version?
Thanks.
