If the previous steps were done correctly, you should see a tab called Import. Photos should automatically open to the Import tab. If it doesn't, open Photos and tap Import.

Next, Tap Import All to import your content, or tap specific items, then tap Import

When the import is complete, you might be asked to Keep or Delete the media on the camera or SD card

You can import content only to your iPhone, iPad, or iPod touch. You can't export content to an SD card or digital camera.
