Will Photos maintain my album structure?
If you have organized your photo libraries in a particular way, you may be concerned that when you import your photos into Photos they will sort themselves into date order. Perhaps, for example, you have scanned in, or imported old photos and want them to be dated according to when they were first taken, rather than when you added them to your library. Will Photos respect your filing system?
Photos folder structure is slightly different to iPhoto. Rather than filtering your photos into Events, your photos will appear in Albums. When you import your library all your images will appear in an iPhoto Events album in date order. Luckily you can batch change dates. Select the image and choose Image > Adjust Date and Time.
Will Photos import my Events from iPhoto?
When you import your iPhoto library you will see an iPhoto Events album in Albums. Inside this album you will find your Events listed by date.
Will Photos maintain my star rankings
Photos lacks the 0 - 5 Star rating system, only letting you make an image a favourite. However, that doesn't mean you will lose the star ratings you've added to iPhoto - Photos turns them into keywords. To find your 5 Star photos pop 5 Star into the Photos' Search field.
iCloud Photo Library questions answered
Will my photos have to be stored in iCloud?
You can choose to store your images in the cloud, or you can choose to store them locally. You don't have to use iCloud.
How can I sync just some of my Photos with iCloud
If you want to store your photos in the cloud via Photos iCloud Photo Library we recommend that you remove duplicates and the worst images, especially if your library is on the large side.
You get 5GB of free storage and we doubt that your photo library is that small, so it is likely that you will be looking at buying more storage from Apple.
Only the default System Photo Library will sync with iCloud, so you can choose just to sync some of your photos to the cloud by limiting the image that appear in that library.
General Photos for Mac questions
How do I import new images to Photos for Mac?
When you plug in your camera or memory stick you'll see an Import button, just like in iPhoto. If you have more than one device plugged in you will be able to chose which one to import from.
How can I rank my images?
You can add images to Favourites, but you can't give them star ratings anymore. However, you can also add keywords to the image - including typing a star rating into the metadata if you are keen to maintain star ratings system used in iPhoto.
