I've generated a few trial smart albums from my main library before making any serious use of them and the behaviour when burning one or more of them to a DVD seems very odd to me, in fact useless, and I wonder if someone can tell me what I'm doing wrong.
The scenario is this. I create a smart album containing say all the photos of one particular person, the photos are "pulled" from a large number of different events. I then highlight the generated smart folder which contains say 210 pictures that the individual appears in and use the Share->Burn command to burn the images to a DVD. What actually happens is that all the albums that the individual pictures have been pulled from are burned to the disc rather than just the photographs that contain this particuler person. So, instead of the 210 pictures I wanted, which ALL contain that individual, I end up with in this case a disc containing 94 events, a total of 5443 images which include the 210 images with this particular person in them, which isn't what I want at all!
I'm selecting the option to burn the disc in the format that can be read by iPhoto, ie. a library disc.
When you did the burn did you select just the Smart Album icon in the left hand pane before using the Share ➙ Burn menu option? What version of iPhoto are you running?
I just ran a test in iPhoto 9.4.2 burning a smart album. What I got is shown in this screenshot:
The original SA had 232 photos in it. The SA in the disk "mini" library had the same 232 photos but also the 40 Events that those 232 photos came from.
Make sure you select just the Smart Album in the left hand pane before using the Share ➙ Burn menu.
