If you currently already have the folder "photo" specified as 
"collection" then you won't be able to add other collections with the 
paths "photo/2015" and "photo/2014" since the "2014" and "2015" 
subdirectories are below "photo" and thus are already included.

However, if you remove the "photo" collection first then you can 
configure 2 collections with the individual paths "photo/2015", 
"photo/2014", etc. which will be shown as separate albums in the album 
view, e.g.

Albums
   2015
   2014

If you have tagged your images, and the tags have been also been written 
to the image files then this should be no problem, since the "new" 
collections are scanned and the Metatags are read from the files.

However, if your tags have *not* been written to the image files then 
Metatags might eventually get lost if you remove the original collection 
and add new ones.

So in this case IMO a safe way would be to
- rename the existing Album "photos" to  "photos.org" or something in DK

- create new directories "photos/2014", "photos/2015" using a file manager

- add the new, empty directories as additional collections in DK

so in DK you should have following albums:

Albums
   photo.org
     2014  (old, with images)
     2015  (old, with images)
   2014    (new, empty)
   2015    (new, empty)

and you can drag and drop the image files from the old to the new albums.

Finally you should close digikam and use a file manager to move other 
photos which you might not want to see in DK into the new "photo" 
folder, e.g.

mv photo.org/2013 photo/

etc.


In *any* case you should make a backup copy of the DK databases 
digikam4.db  and thumbnails-digikam.db, before you start, so you can 
easily go back to the current state if the results are not what you 
expected.
