Apple's iPhone photos are currently in the HEIC (high-efficiency image coding) format, an unusual file type that not every app/software support at the moment. If you do not want to use this standard, such as when editing images, you can change the format in Camera settings. Just open "Settings", find "Camera", and then tap "formats". Finally, select "most compatible". This will also allow your videos to come out as H.264 instead of HEVC.
Tom wants to know what Apple has done with the iPhone 11 camera. He's having issues with editing the software. Leo says that's likely because Apple has adopted the HEIC image codec, which is a new standard that not every program supports. He can change the format in camera settings, but he can also export it as RAW or JPG when sharing. Leo says that Apple saves full-res versions on iCloud, while caching lower-res versions on the iPhone. So when users open it in the photo editor, they have to wait for the phone to download the full-res version before the app can open it.
Anthony is a professional photographer and he's trying to transfer his images and videos from his old iPhone to the new iPhone through his computer. But it's taking forever. Rich says what's likely happening is that it's converting files from the HEIC codec as it transfers. Anthony should go into his settings for image capture and check "keep originals." That should speed things up, especially with video.
