PowerPhotos lets you split your photos in the Photos app into multiple libraries, rather than keeping everything in one giant library. You can easily switch between libraries or view photos in your libraries directly from PowerPhotos without having to open each library.
PowerPhotos also supports searching across all your libraries at once to help you find specific photos. If you use iCloud Photo Library to sync photos to other devices, it can help break up your libraries and save on iCloud storage costs. Use one library to keep smaller collections that you can sync to iCloud, while keeping the bulk of your photos in separate libraries so they don't take up iCloud space. PowerPhotos can analyze your libraries for duplicate photos, display them side by side, and let you get rid of extra copies of photos you no longer need.
Software Features
The ultimate toolbox for photos on Mac
PowerPhotos works with the built-in Photos app on your Mac, providing a range of tools to help you keep your photo collection in order.
Creating and managing multiple libraries
The main window PowerPhotos is not limited to having all your photos in one library, but can work with multiple photo libraries, giving you more options to help you organize your growing photo collection.
Splitting your photos between multiple libraries helps Photos open faster, lets you archive old photos, store some collections on an external hard drive, and reduces the storage space used by iCloud Photo Library.
Copy photos and their metadata
Main Window You can split your library by copying albums and photos with a simple drag-and-drop operation. PowerPhotos will take care of copying the photos and preserving their metadata, including keywords, descriptions, titles, dates, and collection status.
Merge Photo Libraries
Do you want to consolidate a bunch of libraries? PowerPhotos allows you to merge libraries together while cleaning up duplicate photos in the process. Before you make any modifications, you'll see a preview of what the merged library will look like, allowing you to make sure your merged library looks the way you want it.
Find duplicate photos
Main Window Over time, it's easy for multiple copies of the same photo to gradually accumulate in your photo collection. Use PowerPhotos to find duplicate photos in one or more libraries, view them side by side, and separate them into albums from which you can easily delete them.
Browse and Search
The main window uses PowerPhotos' image browser to quickly view photos without opening the photos themselves. Use List View to view detailed photo information and search photos across all your libraries at once.
Migrate iPhoto/Aperture Library
Main Window If you have many existing iPhoto or Aperture libraries that you want to migrate to Photos, PowerPhotos will help automate your migration so you don't have to spend time babysitting this lengthy process.
How to copy a keyword list to another library
Copy a keyword list to another library
One of the key features of iPhoto Library Manager is that when you copy photos from one library to another, it copies the photo's keyword list. However, this only helps with keywords that are actually assigned to one or more of your photos. What if you have a large number of keywords, but some of them aren't actually assigned to any photos in your library? How can you take that keyword list and copy it to another library? Here's one technique that takes advantage of this feature of iPhoto Library Manager:
1. Open the library whose keyword list you want to copy and select a photo in the library. We call this a "dummy" photo. If you don't want to modify any existing photos, you can even copy an existing photo to use as a temporary "dummy."
2. Assign every keyword in your library to the dummy photo (or at least every keyword you'll be bringing into the other library). Note that in iPhoto 6 and earlier, doing this through the keyword pane in the lower left is a real pain, as you have to go through and assign each photo to each keyword over and over again. Try using the Info window (Command-i), which has simple checkboxes for quick assignment of multiple keywords to photos.
3. Copy the photo to the library you want to copy the keyword list to. iPhoto Library Manager will copy the photo and then assign all the keywords in the list to the copied photo, effectively recreating the entire keyword list in the destination library.
Now that the photo has been copied and the keywords have been re-created, you can delete the dummy photo from the destination library. You can also return to the original library and remove all keywords from the dummy photo, or just delete it if you're making a temporary photo for this purpose.
Another similar technique, if you frequently create new libraries and want a standard keyword list within them, is to create an empty library and fill its keyword list using this technique, then leave it as is. Whenever you need a new library, instead of creating an empty one, simply duplicate the library along with the entire keyword list using the Duplicate Library command. Now, all new libraries will start with the same custom keyword list.
Software Features
The PowerPhotos icon is beautifully designed, depicting a small robot holding a photo. The photo is a reminiscent of the colorful, rounded shape of the new Photos app in iOS and OS X. The photos in PowerPhotos are designed by Iconfactory and are of decent quality. Upon opening PowerPhotos, the app automatically imports your Photos app library. If you have multiple libraries, you can quickly switch between them in the leftmost sidebar. The left sidebar is divided into two sections: the photo library and the actions section.
The center section of PowerPhotos categorizes the various photo contents in your photo library, such as panoramas, videos, bursts, and slow motion. On the right are all the photos in your photo library. PowerPhotos offers two modes: list and grid. The + sign in the upper left corner adds a new library, and the - sign deletes it. The two buttons on the right, respectively, search for duplicate photos and open the system's Photos app.
If you have an iPhoto library on your system, PowerPhotos can automatically detect it and help you import it. You can also selectively import and manually add a photo library.
