Just figured it out.
1. First go to your actual camera app and then go to settings and switch your Storage location from Internal Storage to SD Card.
2. Then just take a random photo. (This will create a new folder in your gallery with an SD icon showing where all your future photos will be saved)
3. Finally go to your gallery, go to your camera folder, hold on one pic until the option ALL appears in the top corner. When you click it, go to the settings in your gallery, you can select move to album and pick the one that was created with the SD icon. Then all those photos will copy over to your SD card.
