Hello,
it's possible on El Capitan:
Important: the smart albums will be included in the albums, it's not possible to exclude it.
You can use this AppleScript:
set dest to "/Users/me/Desktop/photos-Albums/" as POSIX file as text -- the destination folder (use a valid path)
tell application "Photos"
repeat with i in albums
set tFolder to dest & (get name of i)
my makeFolder(tFolder) -- create a folder named (the name of this album) in dest
export (get media items of i) to (tFolder as alias) without using originals
end repeat
end tell
on makeFolder(tPath)
do shell script "mkdir -p " & quoted form of POSIX path of tPath
end makeFolder
Open the "Script Editor" application in /Applications/Utilities/
Copy the AppleScript and paste into the window of the "Script Editor".
Change the path of your folder in the first line of the script (use drag/drop to get the correct path of your folder).
if you want the originals, use this --> export (get media items of i) to (tFolder as alias) with using originals
