It is very easy to create albums directly in iPad. Just
Although simple when you have several hundred photos on your iPad things become difficult to maintain.
Using the standard Aperture commands create an album (mine is called iPad-RT) and then add various embedded albums within this. Simply drag the photos you wish to have on your iPad to the relevant album. Close Aperture to ensure the previews are updated.
My understanding is that Aperture syncs the previews to the iPad and not the masters. The size of the preview is set in Aperture Preferences, so make sure this is not set to low,
Connect your iPad to your Mac USB and if iTunes does not start automatically then start it manually. In my system the iPad will go through the standard synchronisation on each new physical connection.
Your iPad should show on the left below Devices. Click on this and then on Photos on the top right (highlighted in my photo below). Select Aperture
in the Sync Photos from list and then select the albums you wish to download/sync. Note it will only download new photos or modified photos.
I also download the last three events, which typically are the last three imports to Mac from one of my digital cameras.
Note: Albums and photos created on iPad by this method cannot be deleted on iPad, the album has to be deleted or photo removed from album in Aperture and then sync removes them from iPad.
This screen is shown during sync showing total photos and total per album.
iPhoto can also be used to control iPad photos in a similar way. The first screen after the iPad is connected is shown here. Note that any new photos on the iPad will automatically be offered for import.
Drag the photos you want to be included on the iPad into the relevant album.
The photos are then synchronised to the selected albums, as for Aperture.
