If you want to continue to use Google Photos, you'll need to move your photos to a personal Google Photos account. The easiest way to do this is through Partner Sharing. To set up Partner Sharing, click the gear at the top right corner of Photos.
Click Partner Sharing.
A box will pop up asking you if you want to limit to photos only after a certain date, leave that at "off". Additionally, you'll be asked whether you want to share all photos or just photos of certain people; choose All Photos.
Click Next, and you'll be asked for an e-mail address to share your photos with. Enter it one associated with a personal Google account and click Next
You'll see a confirmation. Click Send Invitation, but you are not done!
You'll then receive an email at your personal Google address asking you to accept the invite. Click View Invite.
You'll then be asked to accept the invite. Click Accept.
It will then ask you if you want to share your personal photos back. Choose "Not Now"
Once you do that, you'll see the photos. In the corner you'll see "See these photos along with your own" . Click that.
In the box that pops up, choose "Save all photos" and click Done.
Moving to Another Service with Google Takeout
...
*****IMPORTANT: so that you don't download everything in your Google Account, including e-mails, you MUST click "Deselect all" at the top
Scroll down to Google Photos and check that box.
Then, scroll all the way to the bottom and choose "Next step"
Double-check that only 1 item is selected.

You will be e-mailed a link when your export has completed. Click Download your Files.

If necessary, select a location to extract to, and click Extract.
On a Mac, just double-click the zipped file.
